How Much Water Went Into Growing the Food We Eat?

The rains bypassed sunny California in January and February 2020, encouraging talk of another drought. California’s last drought was only declared over a year ago, after two wet winters in a row filled the states reservoirs. To cope with the last drought, instead of building more reservoirs and taking other measures to increase the supply of water, California’s policymakers imposed permanent rationing.

This predictable response ignores obvious solutions. Millions of acre feet of storm runoff can not only be stored in new reservoirs, but in underground aquifers with massive unused capacity. Additional millions of acre feet can be recovered by treating and reusing wastewater, and by joining the rest of the developed nations living in arid climates who have turned to large scale desalination.

All of this, however, would require a change in philosophy from one of micromanagement of demand to one that emphasizes increasing supply. To understand why a focus on increasing supply is vastly preferable to reducing demand, it helps to know just how much water California’s urban residents consume compared to other users.

As a matter of fact, the average California household purchases a relatively trivial amount of water from their utility, when compared to how much water they purchase in the form of the food they eat. For this reason, reducing residential water consumption will not make much of a difference when it comes to mitigating the effects of a prolonged drought.

To illustrate this point, it is necessary to determine just how much water is available to Californians, and how much of that water is being consumed by residential households in California. When making this analysis, one must not only estimate how much water California’s households purchase from their utility, but how much water is embodied in the food they eat.

Total Annual Water Supply and Usage in California

Here’s a rough summary of California’s annual water use. In a dry year, around 150 million acre feet (MAF) fall onto California’s watersheds in the form of rain or snow, in a wet year, Californians get about twice that much. Most of that water either evaporates, percolates, or eventually runs into the ocean. In terms of net water withdrawals, each year around 31 MAF are diverted for the environment, such as to guarantee fresh water inflow into the delta, 27 MAF are diverted for agriculture, and 6.6 MAF are diverted for urban use. Of the 6.6 MAF that is diverted for urban use, 3.7 MAF is used by residential customers, and the rest is used by industrial, commercial and government customers.

Put another way, Californians divert 65 million acre feet of water each year for environmental, agricultural and urban uses, and the planned permanent 25% reduction in water usage by residential customers will only save 0.9 million acre feet per year – or 1.4% of total statewide water usage. One good storm easily dumps ten times as much water onto California’s watersheds as would be saved via a 25% reduction in annual residential water consumption.Armed with these facts, there’s a strong argument that cutting back on residential water consumption will not make a significant difference in California’s overall water use. There are additional facts that can put this argument into an even sharper context: How much water do California’s households consume in terms of the water that was required to grow the food they eat, and how does that amount compare to the water they purchase from their utility for indoor/outdoor use?

The “Water Footprint” of Food per Ounce and per Calorie

While the information to determine this is readily available, it isn’t typically compiled in this context, so here goes. The best source of comprehensive data on the “water footprint” for various types of food comes from the Water Footprint Network, a project initially funded by UNESCO. An excellent distillation of that information was produced in April 2015 by Kyle Kim, John Schleuss, and Priya Krishnakumar, writing for the Los Angeles Times. Information on calories per ounce was found on the website “fatsecret.com.” Information from these various sources is summarized on the following table.

As can be seen on the above chart, when evaluating the water efficiency of various food sources, it is misleading to rely only on gallons per ounce, since the number of calories per ounce are highly variable. But putting these two variables together to calculate a gallons per calorie measurement is quite useful. Clearly, meat products require a huge amount of water per calorie. The most efficient sources of meat protein are found in chicken, which at 0.37 gallons per calorie is around four times as water-efficient as red meat. Some sources of protein from vegetables are surprisingly efficient, including avocados at 0.20 gallons per calorie, and the almond – much maligned as a water waster – at 0.15 gallons per calorie. But we digress.

How much water does it take to feed the average household in California, and how does that compare to the amount of water they buy from the utility for indoor/outdoor use?

Total Annual Consumption of Water-in-Food per Household

The next table, below, provides this estimate based on a typical diet. The estimate of 2,000 calories necessary to sustain the average human (men, women, children) comes from WebMD. The breakout of food consumption by category, while somewhat arbitrary, relies on data on “the average American diet“c ompiled by researcher Mike Barrett, writing for the Natural Society website. In turn, Barrett relied on USDA and other government sources for most of his data, which is reflected here.To summarize, in one year, the average American consumes a quantity of food that required 1.3 acre feet of water to grow. In turn, at 2.91 people per household in California, the average household consumes a quantity of food per year that requires 3.9 acre feet of water to grow.

Average Annual Water Use per California Household

Putting all of this together yields a revealing table, below, that shows that the average California household purchases a relatively trivial amount of water from their utility, when compared to how much water they purchase in the form of the food they eat. By dividing the 3.7 million acre feet of water used by residences each year in California by the 12.8 million households in California, the average annual water consumption per household is 0.289 acre feet. By contrast, the amount of water that is eaten, so to speak, by the average California household is 3.9 acre feet, thirteen and a half times as much.

By the way, it is irresistible to point out that drinking water, that quantity each human requires for their daily hydration, based on the 0.5 gallon per day recommendation from the Mayo Clinic, comes out to a paltry 0.0016 acre feet per year per household – not even a rounding error when compared to the other uses. Think about that the next time you have to ask for your water at a California restaurant.There is no Reason Water Cannot be Abundant and Affordable

For decades, when it comes to water, California’s policymakers have prioritized demand restrictions instead of supply enhancements. This is consistent with their priorities in other critical areas, certainly including energy and transportation. “Induced demand,” the idea that if you build it, more will use it, is the nightmare axiom that governs this policy. It certainly would never have to do with the possibility they’d rather put all those operating funds into their pay and pensions instead of expanding public infrastructure.

The problem with this, however, is that eventually the conservation option begins to yield diminishing returns, and then all you have left is punitive rationing. And once via punitive rationing you have wrung all of the redundancy and surplus out of the system, you have no resiliency if any part of the system fails. That is where California is today. The abundance choice is the only viable option if Californians are to improve their quality of life. In no particular order, here are some reality checks that California’s voters and elected officials ought to consider:

(1)  Projects that increase water supply via sewage reuse, runoff storage via reservoirs or aquifers, and desalination, are options that benefit all users, urban and agricultural.

(2)  Increasing the supply of water from diverse sources creates system resiliency which can be of critical benefit not only in the face of persistent drought, but also against catastrophes that may, for example, disable a pumping station on a major aqueduct.

(3)  The energy costs to desalinate seawater, approximately 4.0 kilowatt-hours per cubic meter, are overstated. Desalination plants can be co-located with power plants, eliminating power loss through transmission lines, whereas far-flung pumping stations consume significant amounts of electricity. Depending on transmission loss and desalination plant efficiency, the amount of lift beyond which desalination consumes less power than pumping is only about 1,500 feet.

(4)  Public investment in water saving home appliances, for example via tax rebates to consumers to purchase them, by contrast, do not increase the overall supply of water.

(5)  It is nearly impossible to engage in excessive use of indoor water in a household, because 100% of the sewage is treated and released as clean outfall to the environment. Moreover, sewage is increasingly treated and reused as potable water, and eventually 100% of indoor water waste will be cycled immediately back for reuse by households.

(6)  One preferred way to reuse household sewage is referred to as “indirect potable reuse,” where the treated water is percolated into aquifers where it is eventually pumped back for household reuse. This practice has the virtue of banking the water against supply disruptions, recharging the aquifer which is especially beneficial in coastal areas where there can be salt water intrusion, and even, as water is repeatedly cycled through the aquifer, causing an ongoing improvement to the quality of the water in the aquifer as treatment progressively reduces levels of undesirable residual toxins.

(7)  While achieving 100% reuse of sewage will render indoor water conservation pointless, the virtues of outdoor water use are understated. Healthy landscaping, consisting of abundant vegetation including lawns, reduce the incidence of dust-borne pathogens, reduce the incidence of asthma, and clean and moisturize the air. Replacing grass playing fields with artificial turf introduces toxins, causes more ACL and other sports injuries, and retains heat – often to the point of making these faux fields unplayable unless they are, ironically, watered.

(8)  Simply giving up consumption of red meat would reduce the average household’s water consumption by nearly 2.0 acre feet per year. By comparison, the average Californian household’s total water consumption from the utility averages 0.29 acre feet per year. That is, just replacing consumption of red meat with an equivalent caloric intake of chicken will save the average household seven times as much water as they buy from the utility for all uses, indoor and outdoor.

Policies designed to reduce household water use are a good idea, but must be kept in perspective. What has already been done is more than enough, and priorities now must shift towards investment in infrastructure to increase the supply of water. Nearly all water diversions in California, about 90%, are either to preserve ecosystem health or to supply agriculture. Indoor water overuse is becoming a myth, and will become entirely irrelevant as soon as 100% sewage reuse capacities are achieved. Outdoor water use should not be thoughtless, but allowing grass and perennials to die, or converting landscaping to “desert foliage,” is a cultural shift that is not necessary or desirable.

Along with investing in infrastructure to increase the supply of water, public education to help Californians adopt healthier diets would have the significant side benefit of being sound water policy. A trivial change in patterns of food consumption yields a major reduction in water required for food. For example, a public education campaign that caused a voluntary 10% reduction in red meat consumption (from 25.0% of all calories to 22.5% of all calories) would reduce California’s water consumption by 2.5 million acre feet per year. By comparison, total outdoor residential water consumption in California is estimated at only 1.8 million acre feet per year.

Perhaps, in lieu of renouncing escalating and entirely unnecessary mandates to reduce household water use, those of us who love our lawns might at least be granted a waiver if we were to present an annual affidavit to document our below-average consumption of red meat. Our smart refrigerators might actually submit the report to the utility, sparing us the paperwork.

Towards a Grand Bargain on California Water Policy

When it comes to water policy in California, perhaps the people are more savvy than the special interests. Because the people, or more precisely, the voters, by huge majorities, have approved nine water bonds in the past 25 years, totaling $27.1 billion. It is likely they’re going to approve another one this November for another $8.9 billion.

The message from the people is clear. We want a reliable supply of water, and we’re willing to pay for it. But the special interests – or whatever you want to call the collection of politicians, unelected bureaucrats with immense power, and other stakeholders who actually decide how all this money is going to be spent – cannot agree on policy. A recent article in the Sacramento Bee entitled “Why San Francisco is joining Valley farmers in a fight over precious California water,” says it all. “Precious California water.” But what if water were so abundant in California, it would no longer be necessary to fight over it?

As it is, despite what by this time next year is likely to be $36 billion in water bonds approved by voters for water investments since 1996, the state is nowhere close to solving the challenge of water scarcity. As explained in the Sacramento Bee, at the same time as California’s legislature has just passed long overdue restrictions on unsustainable groundwater withdrawals, the political appointees on the State Water Resources Control Board are about to enact sweeping new restrictions on how much water agricultural and municipal consumers can withdraw from the Sacramento and San Joaquin rivers.

This is a perfect storm, and every conservation, recycling and storage project currently funded or proposed will not make up the shortfall. In 2002, well before these new restrictions were being contemplated, the California Dept. of Water Resources issued an authoritative study, “Averting a California Water Crisis,” that estimated the difference between demand and supply at between two and six million acre feet per year by 2020. An impressive response from the public during the most recent drought, combined with some investment in water infrastructure has narrowed that gap. But the squeeze is ongoing, with tougher challenges and tradeoffs ahead.

Abundance vs Scarcity

When thinking about solutions to California’s water challenges, there is a philosophical question that has to be addressed. Is it necessary to persistently emphasize conservation over more supplies of water? Is it necessary to always perceive investments in more supplies of water as environmentally unacceptable, or is it possible to decouple, or mostly decouple, environmental harm from investment in more water supplies? Is it possible that the most urgent environmental priorities can be addressed by increasing the supply of water, even if investing in more water supplies also creates new, but lessor, environmental problems?

This philosophical question takes on urgent relevance when considering not only the new restrictions on water withdrawals that face Californians, but also in the context of another great philosophical choice that California’s policy makers have made, which is to welcome millions of new immigrants from across the world. What sort of state are we inviting these new residents to live in? How will we ensure that California’s residents, eventually to number not 40 million, but 50 million, will have enough water?

It is this reality – a growing population, a burgeoning agricultural economy, and compelling demands to release more water to threatened ecosystems – that makes a grand political water bargain necessary for California. A bargain that offers a great deal for everyone – more water for ecosystems, more water for farmers, more water for urban consumers – because new infrastructure will be constructed that provides not incremental increases, but millions and millions of acre feet of new water supplies.

The good news? Voters are willing to pay for it.

How to Have it All – A Water Infrastructure Wish List

When considering what it would take to actually have water abundance again in California, the first step is to try to determine the investment costs, imagining a best case scenario where every good idea got funded. Here’s a stab at that list, not differentiating between local, state and federal projects. These are very approximate numbers, rounded upwards to the nearest billion:

Projects to Increase Supplies of Water

(1) Build the Sites Reservoir (annual yield 0.5 MAF) – $5.0 billion.

(2) Build the Temperance Flat Reservoir (annual yield 0.25 MAF) – $3.0 billion.

(3) Raise the height of the Shasta Dam (increased annual yield 0.5 MAF) – $2.0 billion.

(4) So Cal water recycling plants to potable standards with 1.0 MAF capacity – $7.5 billion.

(5) So Cal desalination plants with 1.0 MAF capacity – $15.0 billion.

(6) Desalination plants on Central and North coasts with 0.5 MAF capacity – 7.5 billion

(7) Central and Northern California water recycling plants to potable standards with 1.0 MAF capacity – $7.5 billion.

(8) Facilities to capture runoff for aquifer recharge (annual yield 0.75 MAF) – $5.0 billion.

Total – $52.5 billion.

Projects to Increase Resiliency of Water Distribution Infrastructure

(9) Retrofit every dam in California to modern standards, including Oroville and San Luis – $5.0 billion.

(10) Aquifer mitigation to eliminate toxins with focus on Los Angeles Basin – $7.5 billion.

(11) Retrofit of existing aqueducts – $5 billion.

(12) Seismic retrofits to levees statewide, with a focus on the Delta – $7 billion.

Total – $24.5 billion.

The total of all these projects, $77 billion, is not accidental. That happens to be the latest best case, low-ball estimate for California’s completed high speed rail project. Without belaboring the case against high speed rail, two comparisons are noteworthy.

First, an ambitious program to create water abundance in California and water infrastructure resiliency in California based on this hypothetical budget is achievable. These numbers are deliberately rounded up, and the final costs might actually be lower, whereas it is extremely unlikely that California’s high speed rail project can be completed for $77 billion.

Second, because people will actually consume these new quantities of water that are being supplied and delivered, private financing will be attracted to significantly reduce the taxpayer’s share.

The Impact of a $77 billion Investment on Water Supply, Resiliency, and Ecosystems

As itemized above, at a capital cost of $52.5 billion, the total amount of water that might be added to the California’s statewide annual water budget is 5.5 million acre feet.

This amount of water would have a staggering impact on the demand vs. supply equilibrium for water. It is nearly equal to the total water consumed per year by all of California’s urban centers. Implementing this plan would mean that nearly all of the water that is currently diverted to urban areas could be instead used to ensure a cool, swift flow in California’s rivers, while preserving current allocations for agriculture. The options for environmentalists would be almost unbelievable. Restore wetlands. Revive the Delta. Refill the shrinking Salton Sea.

The environmentalist arguments against the three dams are weak. Shasta Dam is already built. The impact of expanding the Shasta Dam is purportedly the worst on McCloud creek, where it will affect “nearly a mile” of what was “once a prolific Chinook salmon stream,” (italics added). That negative impact, which seems fairly trivial, has to be balanced against the profound benefit of having another 500,000 acre feet of water available every summer to generate pulses of swift, cool water in the Sacramento River. The proposed Temperance Flat Reservoir is proposed on a stretch of the San Joaquin River that already has a smaller dam. The Sites Reservoir is an offstream reservoir that will not interfere with the Sacramento River.

The environmental benefits of these dams are not limited to their ability to ensure supplies of fresh water for California’s aquatic ecosystems. They can also be used to store renewable electricity, by pumping water from a forebay at the foot of the dam into the reservoir during the day, when solar energy already brings the spot price of electricity down to just a few cents per kilowatt-hour, then generating hydro-electric power later in the evening when peak electrical demand hits the grid. This well established technology has already been implemented on dams throughout California, and remains one of the most cost-effective ways to store clean, but intermittent, renewable energy. It will also be a profit center for these dams.

The environmentalist arguments against desalination are also weak. The energy required to desalinate seawater is comparable to the energy necessary to pump it from Northern California to the Los Angeles Basin. The outfall can be discharged under pressure a few miles from shore, where it is instantly disbursed in the California current. The impact from the intakes is grossly overstated by environmentalists, when considering that even if all of these contemplated desalination plants were built, the water they would intake is only a fraction of the amount of water taken in for decades by California’s power plants that are sited on the coast and use seawater for cooling.

As for the Delta, the primary environmental threat to that ecosystem is the chance that an earthquake destroys the hundreds of miles of levees, causing the agricultural areas behind those levees to be flooded. Not only would agricultural contaminants enter the water of the Delta, but the rush of water flooding into the areas behind the levees would cause salt water from the San Francisco Bay to rush in right behind, creating conditions of salinity that would take years to remove, if ever.

This is why investing in levee upgrades and a Delta Smelt hatchery is a preferable solution to the Delta tunnels. The tunnels would ensure a resilient supply of water from north to south, but the Delta would still be vulnerable to levee collapse. Levee upgrades and a Delta Smelt hatchery would accomplish both goals – resiliency of the water supply and of the Delta ecosystem. Moreover, the presence of massive water recycling and desalination facilities in Southern California would take a great deal of pressure off how much water would need to be transported through the Delta from north to south.

How to Finance $77 Billion for Water Infrastructure

Funding capital projects depends on three possible sources: operating budgets, general obligation bonds, or revenue bonds. Operating budgets, which used to help pay for capital projects, and which ought to help pay for capital projects, will never be balanced until real pension reform occurs. So for the most part, operating budgets are not a source of funds.

A useful way to differentiate between general obligation bonds and revenue bonds are that the general obligation bonds impose a progressive tax on Californians, since wealthy individuals pay about 60% of all tax revenues in California. Revenue bonds, on the other hand, because they are serviced through sales of, for example, water produced by a desalination plant, are regressive. This is because all consumers see these costs included in their utility rates, and utility bills constitute a far greater proportion of the budget for a low income household.

The Grand Bargain – Creating Water Abundance in California
(MAF = million acre feet)

By financing water infrastructure through a combination of revenue bonds and general obligation bonds, instead of solely through revenue bonds, water can remain affordable for ordinary Californians. The $24.5 billion portion of the $77.0 billion wish list, the funds for dam, aqueduct, and levee retrofits, along with aquifer mitigation, are not easily serviced through revenue bonds. A 30 year general obligation bond for $24.5 billion with an interest rate of 5% would cost California’s taxpayers $1.6 billion per year. Some of these projects, to the extent they are improving water delivery to specific urban and agricultural consumers, might be funded by bond issuances that would be serviced by the agencies most directly benefiting.

To claim that 100% of the revenue producing water projects can be financed through revenue bonds is more than theoretical. The Carlsbad Desalination Plant financing costs, principle and interest payments a nearly $1.0 billion for the plant’s construction, are paid by the contractor that built and operates the plant, with those payments in-turn funded through the rates charged to the consumers of the water. The contractor also retains an equity stake in the project, meaning that additional capital costs incurred privately are also funded via a portion of the rates charged to consumers.

Some of the revenue producing assets on the grand bargain wish list may also have a portion of them paid for by general obligation bonds. Determining that mix depends on the consumer. For example, a revenue bond for the reservoir projects may be applied to agricultural consumers who are willing to pay well above historical rates to have a guaranteed source of water for their orchards, which have to survive through dry years.

For urban consumers in particular, making the more expensive projects financially palatable may require general obligation bonds to cover part of the costs, so the remaining costs are affordable for ratepayers. For example, desalination is a relatively expensive way to produce water, making it harder to finance 100% with revenue bonds. But without desalination, wastewater recycling and runoff capture are not sufficient local sources of water in places like Los Angeles. The overall benefit to Californians of adding another 1.5 million acre feet per year to the state’s water supply, using desalination which is impervious to droughts, may be worth having some of its cost financed with general obligation bonds.

To fund roughly 50% of the revenue producing water supply infrastructure ($26.2 billion) and 100% of the water resiliency and distribution infrastructure ($24.5 billion) on this list would cost taxpayers about $3.0 billion per year. While this might strike some as an unthinkable amount to even consider, these projects meet all the criteria for so-called “good debt.” Constructing them all would solve California’s challenge of water scarcity, possibly forever. All of the projects are assets yielding ongoing and long-term benefits that will outlast the term of the financing. At the same time, water would become so abundant in California that prioritizing water allocations to revive ecosystems would no longer provoke bitter opposition. And California’s residents would live again in a state where taking a long shower, planting a lawn, and doing other water-intensive activities that are considered normal in a developed nation, would once again become affordable and normal.

Other Ways to Help Pay for Water Abundance in California

Enable and Expand Water Markets

Even if a grand bargain is struck between environmentalists, farmers, and water districts, and massive investments are made to increase the supply of water, enabling and expanding water markets will help optimize the distribution of available water resources. Similarly, reforming California’s labyrinthine system of water rights might also help, by making it easier for owners of water rights to sell their allocations. Fostering water markets while protecting water rights have interrelated impacts, and ideally can result in more equitable, appropriate water pricing across the state. It might also help make it unnecessary to impose punitive tiered rates or rationing on household consumers.

Reform Environmentalist Barriers to Development

CEQA, or the California Environmental Quality Act, is a “statute that requires state and local agencies to identify the significant environmental impacts of their actions and to avoid or mitigate those impacts, if feasible.” While the intent behind CEQA is entirely justifiable, in practice it has added time and expense to infrastructure projects in California, often with little if any actual environmental benefit. An excellent summary of how to reform CEQA appeared in the Los Angeles Times in Sept. 2017, written by Byron De Arakal, vice chairman of the Costa Mesa Planning Commission. It mirrors other summaries offered by other informed advocates for reform and can be summarized as follows:

  • End duplicative lawsuits: Put an end to the interminable, costly legal process by disallowing serial, duplicative lawsuits challenging projects that have completed the CEQA process, have been previously litigated and have fulfilled any mitigation orders.
  • Full disclosure of identity of litigants: Require all entities that file CEQA lawsuits to fully disclose their identities and their environmental or, increasingly, non-environmental interest.
  • Outlaw legal delaying tactics: California law already sets goals of wrapping up CEQA lawsuits — including appeals — in nine months, but other court rules still leave room for procedural gamesmanship that push CEQA proceedings past a year and beyond. Without harming the ability of all sides to prepare their cases, those delaying tactics could be outlawed.
  • Prohibit rulings that stop entire project on single issue: Judges can currently toss out an entire project based on a few deficiencies in environmental impact report. Restraints can be added to the law to make “fix-it ticket” remedies the norm, not the exception.
  • Loser pays legal fees: Currently, the losing party in most California civil actions pays the tab for court costs and attorney’s fees, but that’s not always the case with CEQA lawsuits. Those who bring CEQA actions shouldn’t be allowed to skip out of court if they lose without having to pick up the tab of the prevailing party.

Find Other Ways to Reduce Construction Costs

The Sorek desalination plant, commissioned in Israel in 2015, cost $500 million to build and desalinates 185,000 acre feet of water per year. Compared to Carlsbad, which also began operations in 2015, Sorek came online for an astonishing one-sixth the capital cost per unit of capacity. Imagine if the prices Israelis pay to construct desalination plants could be achieved in California. Instead of spending $15 billion to build 1.0 million acre feet of desalination capacity, we would spend less than $3.0 billion. How did they do this?

The bidding process itself adds unnecessary costs to public infrastructure projects. Moving to a design-build process could significantly reduce duplicative work during the plant’s engineering phase. Project labor agreements are another practice that at the very least deserve serious reconsideration. Would it be possible objectively evaluate the impact of project labor agreements, and determine to what extent those mandates increase costs?

What about economies of scale? If ten desalination plants were commissioned all at once, wouldn’t there be an opportunity for tremendous unit savings? What about creativity? Elon Musk, who has disrupted the aerospace industry by building rockets at a fraction of historical prices, said “the construction industry is one of the only sectors in our economy that has not improved its productivity in the last 50 years.” Is he even partly correct? Is that worth looking into?

Shift Government Spending Priorities

Cancel High Speed Rail: The most obvious case of how to redirect funds away from something of marginal value into water infrastructure, which is something with huge public benefit, is to cancel the bullet train. The project is doomed anyway, because it will never attract private capital. But what if Californians were offered the opportunity to preserve the planned bond issuances for high speed rail, tens of billions of capital, but with a new twist? If voters were asked to redirect these funds away from high speed rail and instead towards creating water abundance through massive investment in water infrastructure, there’s a good chance they’d vote yes.

Cancel the Delta Tunnels: By investing in levee hardening, the Delta’s ecosystems can be fortified against a severe earthquake. Reducing the possibility of levee failure protects the Delta ecosystems from their worst environmental threat at the same time as it protects the ability to transfer water from north to south. Investing in hatcheries to increase the population of the threatened Smelt is a far more cost-effective way of safeguarding the survival of that species. And investing in infrastructure on the Southern California coast to make that region water independent greatly reduces the downside of a disruption to water deliveries through the Delta. Canceling the Delta Tunnels would save $20 billion, money that would go a long way towards paying for other vital water infrastructure.

Reform Pensions: The biggest out of control budget item, by far among California’s state and local agencies, is the cost of public sector pensions. A California Policy Center analysis released earlier this year, based on public announcements from CalPERS, estimated that the total employer payments for pensions for California’s state and local government employees is set to nearly double, from $31 billion in 2018 to $59 billion by 2024. And that is a best case baseline. If there is a severe market correction, those required contributions will go up further. No discussion of how to find money for other government operations can take place without understanding the role of pension costs in creating budget constraints.

Reduce State Spending: Other ways to shift spending priorities in California, while worth a discussion, are mostly controversial. Returning the administrator to faculty ratio in California’s UC and CalState systems to its historical level of 1:2 instead of the current 1:1 would also save $2.0 billion per year. Outsourcing CalTrans work and eliminating redundant positions could save $2.5 billion per year. Reducing just state agency headcount and pay/benefits by 20% would save $6.5 billion per year. Just enacting part of that, incremental pension reform for state workers, could stop the runaway cost increases that are otherwise inevitable.

California’s state budget this year has broken $200 billion for the first time. Of that, general fund spending is at $139 billion, also a record. Revenues, however, have set records as well. The rainy day fund is full, and an extra deposit of $2.6 billion has it overflowing. Why not spend that $2.6 billion on water infrastructure? For that matter, why not spend all of the $1.4 billion of cap and trade revenue on water infrastructure?

Financing more water infrastructure will more likely come via public and private debt financing. But redirecting intended future borrowings, in particular for high speed rail and for the Delta Tunnels, could cover most if not all of the infrastructure investments necessary to deliver water abundance to Californians. And at the least, redirecting funds from government operating budgets can defray some of the operating costs, if not some of the capital costs.

Work to Build a Consensus

How many more times will California’s voters approve multi-billion dollar water bonds? The two passed in the last four years, plus the current one set for the November ballot, raise $20 billion, but only $2.5 billion of that goes to reservoir storage. Only another $3.3 billion more goes to any type of supply enhancements – mostly to develop aquifer storage or fund water recycling. Meanwhile, consumers are being required to submit to permanent water rationing, and dubious projects are being funded to save water. Artificial turf is a good example. There isn’t a coach in California who wants their athletes to compete on these dangerous surfaces. On a hot day in Sacramento, the temperature on these “fields” can reach 150 degrees. They are actually keeping sprinkler systems operating on these horrendous boondoggles, just to reduce the deadly heat buildup.

Credibility with voters remains intact to-date, but cannot be taken for granted. If a grand bargain on California’s water future is struck, it will need to promise, then deliver, water abundance to California’s residents.

Change the Conventional Wisdom

California’s current policies have stifled innovation and created artificial scarcity of literally every primary necessity – not just water, but housing, energy and transportation. Each year, to comply with legislative mandates, California’s taxpayers are turning over billions of dollars to attorneys, consultants and bureaucrats, instead of paying engineers and heavy equipment operators to actually build things. The innovation that persists despite California’s unwelcoming policy environment is inspiring.

California’s policymakers have adhered increasingly to a philosophy of limits. Less water consumption. Less energy use. Urban containment. Densification. Fewer cars and more mass transit. But it isn’t working. It isn’t working because California has the highest cost of living in the nation. Using less water and energy never rewards consumers, because the water and energy never were the primary cost within their utility bills – the cost of the infrastructure and overhead was the primary cost.

Changing the conventional wisdom applies to much more than water. It is a vision of abundance instead of scarcity that encompasses every vital area of resource consumption. A completely different approach that could cost less than what it might cost to fully implement scarcity mandates. An approach that would improve the quality of life for all Californians. Without abandoning but merely scaling back the ambition of new conservation and efficiency mandates, embrace supply oriented solutions as well. Build wastewater recycling and desalination plants on the Pacific coast, enough of them to supply California’s massive coastal cities with fresh water. Instead of mandating water rationing for households, put the money that would have been necessary to retrofit all those homes into new ways to reuse water and capture storm runoff.

Paying for all of this wouldn’t have to rely exclusively on public funds. Private sector investment could fund a large percentage of the costs for new water infrastructure. Water supplies could be even more easily balanced by permitting water markets where farmers could sell their water allotments without losing their grandfathered water rights. If the bidding process and litigation burdens were reduced, massive water supply infrastructure could be constructed at far more affordable prices.

The Grand Bargain

Water abundance in California is achievable. The people of California would welcome and support a determined effort to make it a reality. But compromise on a grand scale is necessary to negotiate a grand bargain. Environmentalists would have to accept a few more reservoirs and desalination plants in exchange for plentiful water allocations to threatened ecosystems. Farmers would have to pay more for water in exchange for undiminished quantities. While private financing and revenue bonds could cover much of the expense, taxpayers would bear the burden of some new debt – but in exchange for permanent access to affordable, secure, and most abundant water.

How to Make California’s Southland Water Independent for $30 Billion

The megapolis on California’s southern coast stretches from Ventura County on the northern end, through Los Angeles County, Orange County, down to San Diego County on the border with Mexico. It also includes the western portions of Riverside and San Bernardino counties. Altogether these six counties have a population of 20.5 million residents. According to the California Department of Water Resources, urban users consume 3.7 million acre feet of water per year, and the remaining agricultural users in this region consume an additional 700,000 acre feet.

Much of this water is imported. In an average year, 2.6 million acre feet of water is imported by the water districts serving the residents and businesses in these Southland counties. The 701 mile long California Aqueduct, mainly conveying water from the Sacramento River, contributes 1.4 million acre feet. The 242 mile long Colorado River Aqueduct adds another 1.0 million acre feet. Finally, the Owens River on the east side of the Sierras contributes 250,000 acre feet via the 419 mile long Los Angeles Aqueduct.

California’s Overall Water Supplies Must Increase

Californians have already made tremendous strides conserving water, and the potential savings from more stringent conservation mandates may not yield significant additional savings. Population growth is likely to offset whatever remaining savings that may be achievable via additional conservation.

Meanwhile, the state mandated water requirements for California’s ecosystems continue to increase. The California State Water Board is finalizing “frameworks” that will increase the minimum amount of flowrequired to be maintained in the Sacramento and San Joaquin rivers order to better protect fish habitat and reduce salinity in the Delta. And, of course, these rivers, along with the Owens and Colorado rivers, are susceptible to droughts which periodically put severe strain on water users in California.

At about the same time, in 2015, California’s legislature began regulating groundwater withdrawals. This measure, while long overdue, puts additional pressure on urban and agricultural users.

California’s water requirements for healthy ecosystems, a robust and growing farm economy, as well as a growing urban population, are set to exceed available supply. Conservation cannot return enough water to the system to fix the problem.

How Can Water Supplies Increase?

In Southern California, runoff capture is an option that appears to have great potential. Despite its arid climate and perennial low rainfall, nearly every year a few storm systems bring torrential rains to the South Coast, inundating the landscape. Until the Los Angeles River was turned into a gigantic culvert starting in 1938, it would routinely flood, with the overflow filling huge aquifers beneath the city. Those aquifers remain, although many are contaminated and require mitigation. Runoff harvesting for aquifer storage represents one tremendous opportunity for Southern Californians to increase their supply of water.

The other possibilities are sewage recycling and desalination. In both cases, Southern California already boasts some of the most advanced plants in the world. The potential for these two technologies to deliver massive quantities of potable water, over a million acre feet per year each, is now predicated more on political and financial considerations than technological challenges.

Recycling Waste Water

Orange County leads the United States in recycling waste water. The Orange County Sanitation District treats 145,000 acre feet per year (130 million gallons per day – “MGD”), sending all of it to the Orange County Water District’s “Ground Water Replenishment System” plant for advanced treatment. The GWRS plant is the biggest of its kind in the world. After being treated to potable standards, 124,000 acre feet per year (110 million GPD), or 85 percent of the waste water, is then injected into aquifers to be stored and pumped back up and reused by residents as potable water. The remainder, containing no toxins and with fewer total dissolved solids than seawater, is discharged harmlessly into the ocean.

Currently the combined water districts in California’s Southland discharge about 1.5 million acre feet (1.3 billion GPD) of treated wastewater each year into the Pacific Ocean. Only a small percentage of this discharge is the treated brine from recycled water. But by using the advanced treatment methods as are employed in Orange County, 85% of wastewater can be recycled to potable standards. This means that merely through water reuse, there is the potential to recycle up to another 1.2 million acre feet per year.

Needless to say, implementing a solution at this scale would require major challenges to be overcome. Currently California’s water districts are only permitted to engage in “indirect potable reuse,” which means the recycled water must be stored in an aquifer or a reservoir prior to being processed as drinking water and entering the water supply. By 2023, it is expected the California Water Board will have completed regulations governing “direct potable reuse,” which would allow recycled water to be immediately returned to the water supply without the intermediate step of being stored in an aquifer or reservoir. In the meantime, it is unlikely that there are enough uncontaminated aquifers or available reservoirs to store the amount of recycled water that could be produced.

Desalinating Seawater

The other source of new water for Southern California, desalination, is already realized in an operating plant, the Carlsbad Desalination Plant in San Diego County. This plant produces 56,000 acre feet per year (50 MGD) of fresh water by processing twice that amount of seawater. It is the largest and most technologically advanced desalination plant in the Western Hemisphere. It is co-located with the Encina Power Station, a facility that uses far more seawater per year, roughly ten times as much, for its cooling systems. The Carlsbad facility diverts a portion of that water for desalination treatment, then returns the saltier “brine” to the much larger outflow of cooling water at the power plant.

Objections to desalination are many, but none of them are insurmountable. The desalination plant proposed for Huntington Beach, for example, will not have the benefit of being co-located with a power plant that consumes far more seawater for its cooling system. Instead, this proposed plant – which will have the same capacity as the Carlsbad plant – will use a large array of “wet filters” situated about 1,500 feet offshore, on the seabed about 40 feet below the surface, to gently intake seawater that can be pumped back to the plant without disrupting marine life. The outgoing brine containing 6 percent salt (compared to 3% in seawater) will be discharged under pressure from an underwater pipe extending about 1,800 feet offshore. By discharging the brine under pressure, it will be instantly disbursed and immediately dissipated in the powerful California current.

While desalination is considered to be energy intensive, a careful comparison of the energy cost to desalinate seawater reveals an interesting fact. It takes a roughly equivalent amount of electricity to power the pumps on the California aqueduct, where six pumping stations lift the water repeatedly as it flows from north to south. To guarantee the water flows south, the California aqueduct is sloped downward by roughly one foot per mile of length, meaning pump stations are essential. The big lift, of course, is over the Tehachapi Mountains, which is the only way to import water into the Los Angeles basin.

Barriers to Implementation – Permitting & Lawsuits

The technological barriers to large scale implementation of water recycling and desalination, while significant, are not the primary impediments. Permitting and financing are far bigger challenges. Moreover, financing costs for these mega projects become more prohibitive because of the difficulties in permitting.

The process necessary to construct the proposed Huntington Beach Desalination Plant is illustrative of just how difficult, if not impossible, it is to get construction permits. The contractor has been involved in the permitting process for 16 years already, and despite significant progress to-date, still expects approval, if it comes, to take another 2-3 years.

One of the problems with permitting most infrastructure in California is that several agencies are involved. These agencies can actually have conflicting requirements. Applicants also end up having to answer the same questions over and over, because the agencies don’t share information. And over the course of decades or more, the regulations change, meaning the applicant has to start the process over again. Compounding the difficulties for applicants are endless rounds of litigation, primarily from well-funded environmentalist organizations. The failure to-date of California’s lawmakers to reform CEQA make these lawsuits potentially endless.

Barriers to Implementation – Financing

Even if permitting were streamlined, and all technical challenges were overcome, it would be a mistake to be glib about financing costs. Based on the actual total cost for the Carlsbad desalination plant, just under $1.0 billion for a capacity of 56,000 acre feet per year, the capital costs to desalinate a million acre feet of seawater would be a daunting $18.0 billion. On the other hand, with permitting reforms, such as creating a one-stop ombudsman agency to adjudicate conflicting regulations and exercise real clout among the dozens of agencies with a stake in the permitting process, billions could be shaved off that total. Similarly, CEQA reforms could shave additional billions off the total. How much could be saved?

The Sorek desalination plant, commissioned in Israel in 2015, cost $500 million to build and desalinates 185,000 acre feet of water per year. Compared to Carlsbad, Sorek came online for an astonishing one-sixth the capital cost per unit of capacity. While there’s undoubtedly more to this story, it is also undeniable that other developed nations are able to deploy large scale desalination plants at far lower costs than here in California.

Financing costs for water recycling, while still staggering, are (at least in California) not comparable to those for desalination. The GWRS water recycling plant in Orange County was built at a capital cost of $905 million – $481 million was the initial cost, the first expansion cost $142 million, and the final expansion cost $282 million. This equates to a capital cost of $7,300 per acre foot of annual yield. If that price were to apply for new facilities to be constructed elsewhere in the southland, one million acre feet of recycling capacity could be built for $7.3 billion. Until there is direct potable reuse, however, it would be necessary to add to that cost the expense of either constructing storage reservoirs, or decontaminating aquifers for underground storage.

It’s anybody’s guess, but with reasonable reforms to contain costs, and taking into account additional investments in aquifer mitigation, a budget to make California’s Southland water independent might look like this:

  • 1.0 million acre feet from water recycling – $7.5 billion
  • 1.0 million acre feet from desalination – $15.0 billion
  • 0.5 million acre feet from runoff capture and aquifer mitigation – $7.5 billion

Total – $30 billion.
How much again is that bullet train? Water abundance in California vs. high speed rail

While runoff capture, water recycling, and desalination have the potential to make Southern California’s coastal megapolis water independent, it will take extraordinary political will and innovative financing to make it happen. The first step is for California’s voters and policymakers alike to recognize that conservation is not enough, that water supplies must be increased. Once the political will is established, it will be necessary to streamline the regulatory process, so cities, water agencies, and private contractors can pursue supply oriented solutions, at realistic prices, with a reasonable certainty that their applications will be approved.

How Much California Water Bond Money is for Storage?

Californians have approved two water bonds in recent years, with another facing voters this November. In 2014 voters approved Prop. 1, allocating $7.1 billion for water projects. This June, voters approved Prop. 68, allocating another $4.0 billion for water projects. And this November, voters are being asked to approve Prop. 3, allocating another $8.9 billion for water projects. This totals $20.0 billion in just four years. But how much of that $20.0 billion is to be invested in water infrastructure and water storage?

Summaries of how these funds are spent, or will be spent, can be found on Ballotpedia for Prop. 1, 2014, Prop. 68, 2018 (June), and the upcoming Prop. 3, 2018 (November). Reviewing the line items for each of these bonds and compiling them into five categories is necessarily subjective. There are several line items that don’t fit into a single category. But overall, the following chart offers a useful view of where the money has gone, or where it is proposed to go. To review the assumptions made, the Excel worksheet used to compile this data can be downloaded here. The five categories are (1) Habitat Restoration, (2) Water Infrastructure, (3) Park Maintenance, (4) Reservoir Storage, and (5) Other Supply/Storage.

California Water Bonds, 2014-2018  –  Use of Funds
($=millions)

The Case for More Water Storage

It isn’t hard to endorse the projects funded by these water bonds. If you review the line items, there is a case for all of them. This November, voters will have a chance to approve $200 million to restore Salton Sea habitat, a sum that joins the $200 million of Salton Sea habitat restoration approved by voters in June 2018 in Prop. 68. This November, voters will have a chance to approve $150 million to turn the Los Angeles River back into a river, instead of the concrete culvert that was completely paved over between 1938 and 1960.

Who would be against projects like this? But Californians are heavy water consumers in a relatively arid state. Habitat restoration and park maintenance spending must be balanced against spending for water infrastructure. And conservation mandates must be balanced with investments in infrastructure that increase the overall supply of water. Here’s how Californians are currently managing their water:

Total Water Supply and Usage in California

As can be seen on the above table, residential water consumption represents less than 6% of California’s total water diversions. Indoor water consumption, only about half of that. Yet conservation measures imposed on California’s households are somehow expected to enable more water to be returned to the environment. Even with farmers, where conservation measures have the potential to yield far more savings, putting more irrigated land into agricultural production easily offsets those savings.

Not only does conservation fail to return sufficient water to the environment for habitat maintenance, but there is a downside in terms of system resiliency. During the last drought, when households were asked to reduce water consumption by 20%, it wasn’t an impossible request to fulfill. But as these reductions in consumption become permanent, far less flexibility remains.

California’s climate has always endured periods of drought, sometimes lasting several years. Meanwhile, the population continues to increase, farming production continues to rise, and we have higher expectations than ever in terms of maintaining and restoring healthy ecosystems throughout the state. We cannot merely conserve water. We need to also increase supplies of water. Ideally, by several million acre feet per year.

How Much California Water Bond Money is for Surface Storage?

Prop. 1, approved by voters in 2014, was called the “Water Quality, Supply, and Infrastructure Improvement Act of 2014.” It was marketed as necessary to increase water storage in order to protect Californians against droughts, and was overwhelmingly approved by over 67% of voters. But only about one-third of the money actually went to water storage, and it took nearly four years before any of those funds were allocated to specific storage projects. It was only this month, July 2018, that the California Water Commission awarded grants under their “Water Storage Investment Program.”

A review of these grants indicates that only two of them allocate funds to construct large new reservoirs. The proposed Temperance Flat Reservoir will add 1.2 million acre feet of storage. Situated south of the delta, it will be constructed on the San Joaquin River above a much smaller existing dam. It is estimated to cost $2.7 billion, and the California Water Commission awarded $171 million, only about 6% of the total required funds.

The proposed Sites Reservoir is situated north of the delta, west of the Sacramento river. It is an offstream reservoir, meaning that it will be filled using excess storm runoff pumped out of the Sacramento river during the rainy season. It is designed to store up to 1.8 million acre feet of water and is estimated to cost $5.2 billion to construct. The California Water Commission awarded $816 million, a large sum, but only about 16% of the total required funds.

Two other surface storage projects were approved, expansion of the existing Los Vaqueros and Pacheco reservoirs. Both of these reservoirs serve water consumers in the San Francisco Bay Area, both are supplied water via the California Aqueduct, and both expansion projects are estimated to cost not quite a billion dollars – $795 million for Los Vaqueros and $969 million for Pacheco. The California water commission awarded Los Vaqueros $459 million, and they awarded Pacheco $484 million.

When you consider surface storage, the total capacity of a reservoir is a critical variable, but in many ways more significant is the annual “yield.” This is the amount of water that on average, over decades, the reservoir is planned to deliver to water consumers in normal years. While the Los Vaqueros and Pacheco reservoir expansions combined will add roughly 250,000 acre feet of storage capacity, most of this added capacity is to save for drought years. Los Vaqueros may actually yield up to 35,000 acre feet per year in normal years; Pacheco may yield around 20,000 acre feet per year in normal years.

With respect to annual yields, the case for the much larger Sites and Temperance Flat reservoirs becomes more compelling. The Temperance Flat Reservoir is projected to yield 250,000 acre feet of water in normal years, the Sites Reservoir, a massive 500,000 acre feet. To put this in perspective, 750,000 acre feet represents 20% of ALL residential water consumption in California, or, put another way, each year these reservoirs will yield a quantity of water equivalent to 100% of the reductions achieved via conservation measures imposed on California’s residents during the drought. But will they ever get built?

According to spokespersons for the Sites and Temperance Flats projects, some federal funding is expected, but most of the funding will be from agricultural and urban water districts who will purchase the water (as well as the right to store surplus water in the new reservoir) as soon as its available. The projects still require congressional approval, and then will face a multi-year gauntlet of permit processes and the inevitable litigation. If all goes well, however, both of them could be built and delivering water by 2030.

How Else is Water Bond Money Being Used to Increase Water Supply?

All three of the recent water bonds had some money allocated to invest in water supply. Prop. 1 in 2014, in addition to investing $1.9 billion in surface water storage, allocated $1.4 billion to other projects intended to increase water supply. The projects they approved are either intended to store water in underground aquifers, or fund advanced water treatment and recycling technologies which have the practical effect of increasing water supply. While it isn’t clear from these groundwater storage proposals how much water they would then release in normal years, it appears that cumulatively the projects intend to eventually store as much as 1.0 million acre feet in underground aquifers.

At a combined cost total cost of under one billion, the aquifer storage projects just approved appear to be more cost effective than surface storage. It is also a critical priority to recharge California’s aquifers which have been drawn down significantly over the past several years, especially during the recent drought.

Prop. 68, the “Parks, Environment, and Water Bond” passed earlier this year, while mostly allocating its $4.0 billion to other projects, did allocate $290 million to “groundwater investments, including groundwater recharge with surface water, stormwater, and recycled water and projects to prevent contamination of groundwater sources of drinking water.”

The upcoming Prop. 3, the $8.9 billion “Water Infrastructure and Watershed Conservation Bond Initiative” that will appear on the November 2018 ballot, invests another $350 million to maintain existing, mostly small urban reservoirs, along with $200 million to complete repairs on the Oroville Dam. Prop. 3 also includes $1.6 billion to otherwise increase water storage and supply, including $400 million for wastewater recycling and $400 million for desalination of brackish groundwater.

It is important to emphasize again that all of the funds allocated in these three water bonds are paying for what are arguably worthwhile, if not critical projects. $6.3 billion for habitat restoration, $6.2 billion for water infrastructure, $1.6 billion to maintain our parks. But despite the worth of these other projects, Californians urgently need to increase their annual supply of water to ensure ecosystem health, irrigate crops, and supply urban consumers. And to address that need, out of $20 billion in water bonds passed or proposed between 2014 and this November, only $5.8 billion, less than one-third, is being used to increase water supplies.

What Other Ways Could Water Bond Money Be Used to Increase Water Supply?

Clearly the most important region to increase water supply is Southern California. Two thirds of all Californians live south of the Sacramento River Delta, while most of the rain falls on in Northern California. One way to increase California’s supply of fresh water is to build desalination plants. This technology is already in widespread use throughout the world, deployed at massive scale in Singapore, Israel, Saudi Arabia, Australia, and elsewhere. One of the newest plants worldwide, the Sorek plant in Israel, cost $500 million to build and desalinates 120,000 acre feet of water per year.

Theoretically – because capital costs in California are far higher than in most of the rest of the developed world – desalination offers a cost-effective solution to water scarcity. Uniquely, desalination creates new water, not dependent on rainfall, not requiring storage for drought years, not requiring redirecting of water from other uses. Imagine if Californians invested in desalination plants along the entire Southern California Coast. Eight desalination plants the same size as the Sorek plant would cost $4.0 billion to build if constructed for the same cost as the one in Israel cost. They could desalinate 1.0 million acre feet per year.

The energy costs for desalination have come down in recent years. Modern plants, using 16″ diameter reverse osmosis filtration tubes, only require 5 kWh per cubic meter of desalinated water. This means it would only require a 700 megawatt power plant to provide sufficient energy to desalinate 1.0 million acre feet per year. Currently it takes about 300 megawatts for the Edmonston Pumping Plant to lift one million acre feet of water from the California aqueduct 1,926 ft (587 m) over the Tehachapi Mountains into the Los Angeles basin. And that’s just the biggest lift, the California aqueduct uses several pumping stations to transport water from north to south. So the net energy costs to desalinate water on location vs transporting it hundreds of miles are not that far apart.

The entire net urban water consumption on California’s “South Coast” (this includes all of Los Angeles and Orange County – over 13 million people) is 3.5 million acre feet. It is conceivable that desalination plants producing 1.0 million acre feet of new water each year, combined with comprehensive sewage reuse and natural runoff harvesting could render the most populous region in California water independent.

Why is Infrastructure so Expensive in California?

The Carlsbad desalination plant in San Diego cost $925 million to build, and it has a capacity of 56,000 acre feet per year. That is a capital cost per acre foot of annual yield of $16,500. How is it that the Sorek desalination plant in Israel cost $500 million to build and has a capacity of 120,000 acre feet per year – a capital cost per acre foot of annual yield of only $4,100? Why did it cost four times as much to build the Carlsbad desalination plant?

This is the prevailing question when evaluating infrastructure investment in California. Why does everything cost so much more? The Sites reservoir is projected to cost $5.2 billion. An off-stream reservoir of equal size, the San Luis Reservoir, was constructed in California in the 1960s at a total cost, in 2018 dollars, of $2.3 billion. That all-in cost includes not just the dam, but also includes pumping stations, the forebay, the intertie to the California Aqueduct, and conveyances to get some of the water over the Diablo Range into the Santa Clara Valley. All of these costs (in today’s dollars) for the San Luis Reservoir, compared to the proposed Sites Reservoir, cost less than half as much. Why?

It’s easy to become enthusiastic about virtually any project that will increase our resiliency to disasters and droughts, improve our quality of life, steward our ecosystems, and hopefully create abundance of vital resources such as water. But when considering the need for these various projects, it is equally important to ask why they cost so much more here in California, and to explore ways to bring costs back down to national and international norms. We could do so much more with what we have to spend.

Water Rationing Law Exemplifies the Malthusian Mentality of California’s Legislators

As reported in the Sacramento Bee and elsewhere, on May 31st Gov. Jerry Brown “signed a pair of bills Thursday to set permanent overall targets for indoor and outdoor water consumption.”

After pressure from the Association of California Water Agencies and others, the final form of these bills, Assembly Bill 1668 by Assemblywoman Laura Friedman, D-Glendale, and Senate Bill 606 from state Sen. Bob Hertzberg, D-Los Angeles, offers water districts more flexibility in enforcing the new restrictions. But the focus of AB 1668, limiting indoor water use to 50 gallons per resident per day, is a step too far. Way too far.

There’s nothing wrong with conserving water. But urban water consumption in California is already low, and squeezing even more out of Californians will be costly and bothersome without making much difference in the big picture. Here is a table showing California’s overall water consumption by user:

Total Water Supply and Usage in California – 2010

As can be seen, in a state where total human water diversions total around 65 million acre feet (MAF) per year [1], in 2010 residential customers only consumed 3.7 MAF [2, 3]. According to more recent data obtained by the Sacramento Bee from California’s State Water Resources Control Board, by 2017 the average California resident consumed 90 gallons per day, which equates to around 4.0 MAF per year. Slightly more than half of that is for indoor water, which means that on average, Californians are already consuming less than 50 gallons per day per resident!

So why the new law? We must immediately rule out the desire to save significant amounts of water. On average, Californians are already in compliance with the new restrictions on indoor water consumption, meaning only a minority of households, those over the new cap, will be forced to reduce consumption. And while AB 1668 also mandates individual “water budgets” for outdoor water consumption, even if they cut all outdoor water use by another 20%, that would only save 400,000 acre feet. But at what cost?

THE COST TO FURTHER REDUCE INDOOR WATER CONSUMPTION

Here is a fairly recent analysis of what it costs to implement comprehensive indoor water savings [4]:

Cost to Retrofit a Home to Reduce Water Consumption

That’s a lot of money. But why? How many households are still “overusing” water, if the average consumption is only around 50 gallons per day?

For what it would cost Californians who are not taking their clothes to the laundry mat, who prefer to wash their dishes in the sink, who are not willing to stand under shower heads that cannot rinse soap out of long hair, who don’t want to purchase side loading dishwashers because it hurts their back to load and unload them, how much water will actually be saved? And how does one “overuse” indoor water? Doesn’t it flow down to the sewage treatment plant, where these plants release all that water back into the streams and aquifers, or even in some cases pump the water back uphill to be reused by residents?

THE COST TO FURTHER REDUCE OUTDOOR WATER CONSUMPTION

For outdoor water use, the solutions are even more draconian, and, of course, are disproportionately aimed at people who happen to live in homes with yards. People with lawns where their children play, people with trees that provide shade, people with aesthetically pleasing hedges that offer privacy, people with who love to grow flowers and vegetables – people who love living things. In the short run, these people will be visited by water agency bureaucrats, who will assign a “water budget.” How much will that cost, forcing local water agencies to reach out individually to 12.5 million residential property owners?

In the long run, the costs to manage outdoor water use will get much higher. Every home will need to have two meters, one to measure indoor water use, one to measure outdoor water use. These meters, increasingly, will be “smart,” able to monitor time-of-day use in anticipation of variable pricing depending on when you water. (Don’t water your plants after 9 a.m.!) And eventually, first in new construction, and later in retrofits, every home will have two sources of water supply – one pipe to provide potable water for indoor use, and a separate pipe to provide marginally less potable reclaimed water for outdoor use.

This is epic folly. These conservation measures, as described, are going to cost consumers tens of billions of dollars. When fully implemented, the total annual savings might be around 500,000 acre feet. That’s less than one percent of California’s total human water diversions for agriculture, the environment, commercial, industrial, and residential use.

And not one dime of this money will be instead paying for water treatment, water storage, or desalination projects that could add millions of acre feet to California’s annual water supply.

THE ALTERNATIVE TO THE MALTHUSIAN MENTALITY

Thomas Mathus was an English cleric and scholar living in the early 19th century who developed the theory that global population increases exponentially, while global production increases arithmetically. His theory, and the eventual collapse of civilization that it implies, has enjoyed lasting and ongoing influence. In California, it found its earliest expression in a 1976 speech by Gov. Jerry Brown, who announced that we had entered an “era of limits.” For over forty years now, Governor Brown, and like-minded environmentalists and the politicians they’ve influenced, have embraced the Malthusian vision. But there is an alternative.

One of the most thoughtful and bipartisan visions to counter the Malthusian mentality is offered by the so-called EcoModernists, who in April 2015 published the “EcoModernist Manifesto.” The powerful premise they offer to confront the Malthusians is this: “Both human prosperity and an ecologically vibrant planet are not only possible, but inseparable. By committing to the real processes, already underway, that have begun to decouple human well-being from environmental destruction, we believe that such a future might be achieved. As such, we embrace an optimistic view toward human capacities and the future.”

The devil is in the details, of course. What “real processes” are they referring to? One of the authors, Michael Shellenberger – who just ran as a Democratic gubernatorial candidate in this week’s primary – offers concrete examples. Shellenberger, who runs the nonprofit “Environmental Progress” in Berkeley, is a progressive Democrat. And yet he strongly advocates nuclear power, desalination plants, and permitting suburban housing developments on California’s vast tracts of cattle rangeland.

There is a convergence possible here, of pro-growth progressive Democrats joining independent voters and Republicans to embrace ecomodernism instead of malthusianism. In practical terms, this would mean rejecting rationing of water, energy, land and transportation, and instead investing in infrastructure for the 21st century.  In ideological terms, it would mean rejecting environmentalist extremism rooted in pessimism in favor of economic growth rooted in optimism.

THE HIDDEN AGENDA OF CALIFORNIA’S MALTHUSIANS

California’s voters have not questioned Malthusian policies, partly because they’ve been oversold the environmentalist agenda, and partly because too many of them have been convinced that nothing matters more than the color of their skin or the consequences of their gender status. As a result, leftist oligarchs have been left free to consolidate their interests. Water rationing is just one manifestation of policy-driven artificial scarcity. This Malthusian policy also informs suppression of energy development, land development, and sensible investment in road and freeway upgrades. Public money is diverted to preposterous projects such as high-speed rail, while private investment in energy and housing is proscribed to exclude all but the wealthiest players. And those politically connected billionaires then make outrageous profits when their products – energy, utilities, housing – are produced at constant costs but sold at scarcity driven sky-high prices.

The reason Malthusian ideology constitutes the conventional political wisdom in California has little to do with the environment. It has to do with power and profit. These spectacularly wealthy special interest billionaires have coopted politicians, mostly Democrats, to spew the rhetoric of environmentalism and identity politics because it makes them richer, at the same time as it has made everyone else poorer. Everyone knows that California has the highest cost-of-living in the United States. But less understood is where all that money is going. It is going into the pockets of left-wing billionaires. To ensure government complicity, government unions get their cut, in the form of staggeringly over-market rates of pay and benefits.

POLICIES SHOULD NURTURE ABUNDANCE, NOT ENFORCE RATIONING

Permanent water rationing sets a horrific precedent. It also is just the wrong way to solve water scarcity. Let farmers sell their water to cities without losing their grandfathered water rights. For that matter, reform the water rights that allow farmers to buy water for next to nothing. Invest in more surface and ground storage to harvest storm runoff. Build desalination plants on the coast of Los Angeles County – BIG ones like they use in the Middle East, producing millions of acre feet per year – using less energy than the Tehachapi pumps.

Water is life. People should be able to use as much water as they are willing to pay for, and if they are required to pay a slight premium for overuse, that can fund investment in more water infrastructure. But the law as written will impose punitive fines for overuse. For less money than the cost of implementing water rationing, Californians could experience water abundance. From fragrant lawns to a rejuvenated Salton Sea, to not having to choose between taking a shower or doing the laundry, Californians can enjoy a better quality of life.

We don’t have to live in a society defined by Malthusian struggle. We can create abundance of water and energy in ways that are largely if not completely decoupled from environmental harm. Conservation has its place but when it is the only solution and is not accompanied by increasing supply it reveals its hidden agenda: Greed for money on the part of the firms that manufacture the instruments of conservation, greed for power on the part of the politicians that enforce conservation, and a contempt for the aspirations of ordinary people on the part of environmentalists who have let their principles run amok.

Nobody should have to submit to monitoring of how they use water and submit to punitive fines if they use more than their ration. The idea that everyone has to submit to draconian restrictions on their water use is ridiculous. It comes from a Malthusian mentality that is admirable in moderation and tyrannical in the extreme.

California’s Failure to Store Water Exemplifies its Political Dysfunction

In 2017, when cracks appeared in the Oroville Dam’s spillway, more than 180,000 Californians faced the prospect of floods. The emergency came a few years after Californians had overwhelmingly approved Proposition 1, a ballot measure to spend $7.1 billion on water-storage projects. In the drought-stricken Golden State, where runoff from rain and snowmelt races uselessly into the Pacific Ocean, the proposition won wide support, with voters approving it, two-to-one. But four years after passage, the state water commission has yet to assign a dime of funding for storage.

California once performed miracles in building infrastructure to quench the thirst of its residents and agricultural producers. In the 1960s, Governor Pat Brown oversaw construction of the San Luis Reservoir, capacity 2 million acre-feet. Approved for construction in 1963, it was completed by 1968—five years from start to finish. Those days are long gone. Any surface-storage project now faces years of litigation from environmental groups such as the powerful Sierra Club. At every stage in the construction process, delays of months or years ensue to resolve well-funded lawsuits launched under every conceivable pretext, from habitat destruction to inundation of Native American artifacts.

Nevertheless, the California Water Commission has finally announced its plans to fund new projects with the money from Proposition 1. Many Californians were surprised to learn that the proposition’s fine print stipulated that only a third of the money was ever intended to fund water storage. The rest is earmarked for other projects, ranging from habitat restoration to levee upgrades. Neither the commission nor most of the applicant agencies offer clarity as to how much additional storage the projects will add to California’s normal water supplies in an average year.

Clearly, some of the projects will make a tremendous difference to California’s parched water economy. The proposed Sites Reservoir, to be built just west of the Sacramento River, promises a capacity of nearly 2 million acre-feet; it alone could contribute a half-million acre-feet or more to the state’s water supply even in drought years, and much more in years with normal rainfall. Similarly, the Temperance Flat Reservoir will expand an existing reservoir on the San Joaquin River. Propitiously located south of the delta, this 1.3 million acre-foot construction could contribute 250,000 acre-feet or more to California’s water supply, even in drought years.

To appreciate how much capacity these two projects would add, consider that California’s total residential water consumption—indoor and outdoor combined —is only 4 million acre-feet per year. None of the other proposed projects comes close to matching these two, but in any case, it will be years before this new infrastructure can capture one drop of rain or runoff. The Sites Reservoir application anticipates completion by 2029; the Temperance Flat Reservoir, by 2033. Constant litigation, combined with years of legislation empowering unions and state agency bureaucrats to slow construction, have quadrupled the time required to build—and sent costs soaring. In 2018 dollars, Pat Brown’s San Luis Reservoir cost $672 million; the Sites Reservoir is projected to cost $5.2 billion—seven times as much, for a nearly identical facility.

To eliminate politically contrived shortages, Californians should embrace an all-of-the-above strategy to increase water supplies. They should select projects that yield the best return on investment while they take a hard look at what’s driving construction costs out of sight. Proposition 1 was a mandate to solve a solvable problem—store runoff to eliminate water scarcity. But California legislators have dragged their feet on implementation, betraying their constituents and exemplifying the state’s dysfunctional political culture. When it comes to water issues in California, not just quality of life, but life itself, is at stake.

The Scarcity Profiteers Are Coming For Your Water

Have you experienced water faucets that spray tiny jets of water onto your hands? You know, those eight tiny jets of water, each about 1.0 millimeter in diameter, that are emitted with so much pressure that the paltry quantity of water bounces off your skin before you can get it wet enough to apply soap, and makes rinsing the soap off nearly impossible? You can find these water faucets in airports and other public places, where they constitute a minor annoyance. But wait. Thanks to California’s state legislature, they’re on their way into your home.

You’ll just love your personal space filled up with these expensive gadgets. For example, these faucets will probably require voice-activation, turn off after ten seconds, and send a report to your utility in order to help you manage your usage patterns. Smart faucets. Smart washers. Smart dish washers. Smart shower heads and smart toilets – all coming your way, thanks to the California State Legislature and their partners, the scarcity profiteers of Silicon Valley.

You’ll love how all these water-sipping, next-generation durable goods can go “down,” get hacked, don’t work very well, and require annual warranty payments. You’ll also love purchasing bargain basement annual software upgrades, but only affordable, barely, if you join their green team club for life special VIP program. You’ll love how the control panel on your washer will look like the bridge of a starship, and can only be operated after you’ve mastered the virtual version of a two-inch thick instruction manual.

California’s ruling coalition of government employee unions, extreme environmentalists, and high-tech billionaires are at it again, this time with a water conservation bill, AB 1668, that is going to impose a mandatory limit of 55 gallons per person per day on indoor water consumption. Bring on the gadgets.

To put the impact of this bill into perspective, consider what it would cost to retrofit a household to reduce indoor water consumption:

COST TO RETROFIT A HOME TO REDUCE WATER CONSUMPTION

The biggest cost on this table is the cost for a tankless water heater or a hot water circulation system, necessary if we don’t want to waste water while waiting for it to get hot. Because there’s no good solution to that problem, this is a significant source of water waste that is blithely ignored by water conservation activists. It’s reasonable to expect people in a developed, wealthy nation like America to wait until they have warm water before washing their hands, shaving, hand washing dishes, or showering. And there is no way a person is going to bring their indoor water usage down to 55 gallons a day without either performing all these tasks with cold water, or by installing a system to deliver instant hot water.

But if every Californian did their best to comply with AB 1668, could they reduce their water usage to 55 gallons per day? The next table shows how much they could save, using USGS data. Please note the USGS data is for America, not for California, where decades of conservation incentives have already yielded tremendous reductions in use. Per capital indoor water use in California isn’t anywhere near 139 gallons per day. More on that later.

PER CAPITA POTENTIAL WATER SAVINGS USING WATER EFFICIENCY APPLIANCES

Apart from water efficient toilets which save water and don’t require lifestyle changes, there’s not much here that isn’t expensive and inconvenient. Notwithstanding the fact that Silicon Valley moguls are salivating over the prospects of subsequent mandates that will require all these retrofit appliances to be “smart,” they aren’t going to make life better. Low flow shower heads require longer duration showers, especially if you have to rinse shampoo out of long hair. Consumer reports offer mixed reviews on low water consumption dishwashers and washing machines. Some of us like to wash our dishes by hand – in many cases because it’s less time consuming. And who wants to pull wet clothes out of side loading washers? As for waiting for hot water to make it to faucets, there’s no inexpensive and effective solution.

Enforcing the 55 gallon indoor limit will also be costly not only for California’s residents, but for every water utility in the state. After all, to regulate indoor water consumption, you have to measure indoor water consumption separately from outdoor water consumption. And, of course, residential outdoor water consumption is also in AB 1668’s cross hairs. To accomplish this, AB 1668 calls for dedicated outdoor water meters, separate from indoor water meters, and it calls for water utilities to prepare a water “budget” for each customer parcel based on the size of the parcel and other factors such as the local climate.

THE COST/BENEFIT OF RESIDENTIAL WATER RATIONING

Since AB 1668 proposes to effectively ration residential water consumption, at staggering expense, it’s worthwhile to explore the cost and benefit of this policy. If we assume that five million of California’s 12.5 million households still have legacy appliances, just the retrofit would cost these unlucky homeowners $37.5 billion. But it doesn’t end there, because the water utilities would have to install indoor/outdoor meters on around 10 million households (some households are in multi-family dwellings with no yard or a shared yard). Assuming the cost to install these meters and conduct site visits to assign individual outdoor “water budgets” at $1,000 per household means another $10 billion will have to be spent – i.e., implementing AB 1668 will cost $47 billion.

But how much water would actually be saved, for $47 billion? According to the most authoritative study available on current indoor water consumption, the average Californians uses 62 gallons per day. (ref. California Water Plan Update 2013 Chapter 3, page 12, 1st paragraph “Indoor Residential.”) This means that if California’s 40 million residents got their indoor water use down to 50 gallons per day from 62 gallons per day, it would save 537 thousand acre feet per year (0.54 million acre feet). This is a minute fraction, less than 1%, of California’s total water diversions for environmental, agricultural, and urban uses.

AB 1668 is not about saving water. It’s about control. It’s about power and profit for special interests. Otherwise we could just expand sewage treatment plants, which we should do anyway. How can you waste indoor water if it can go down the drain, to be treated and pumped right back up the hill for reuse?

Let’s keep this in perspective by imagining best case scenarios whereby indoor and outdoor residential water use is dramatically reduced. If Calfornia’s 40 million residents reduced their household water consumption by another 20%, it would only save 0.74 million acre feet per year. An impossible 40% reduction? Savings of 1.5 million acre feet per year. For one-tenth the cost, the proposed “off-stream” Sites Reservoir could easily capture over 2.0 million acre feet each year in storm runoff. Just one good storm dumps ten times that much water onto California’s watersheds.

TOTAL ANNUAL WATER SUPPLY AND USAGE IN CALIFORNIA

So what could Californians do instead with $47 billion? We’ve looked at this before. Limiting ourselves to water infrastructure, here’s a list:

WAYS TO CREATE WATER ABUNDANCE IN CALIFORNIA

First of all, market-based incentives can eliminate water scarcity at almost no cost. For example: Allow farmers to sell their water allotments at market rates without losing their vested rights. Or permit utilities to engage in mild price hikes that encourage people to use less water, instead of resorting to punitive tiered pricing or rationing. These alternatives, to some extent, have already been tried. They work. But if you accept the premise that increasing the absolute supply of water in California is desirable – here are the capital costs for water infrastructure that would create water abundance in California for decades to come.

  • Desalinate 1.0 million acre feet of seawater  –  $15 billion.
  • Reclaim and reuse 2.0 million acre feet of sewage  –  $10 billion.
  • Build the Sites Reservoir for off-stream storage of 2.0 million acre feet of run-off  –  4.4 billion.
  • Build the Temperance Flat Reservoir for 1.3 million acre feet of storage  –  3.3 billion.
  • Aquifer recharge to store runoff – there isn’t even a good study exploring this option at a statewide level.

As can be seen, all of these water infrastructure projects could be built for $32.7 billion. They could be financed via infrastructure bonds, increased rates to consumers, redirection of funds currently being squandered on high-speed rail, or even redirection of proceeds from carbon emission auctions.

What California’s ruling junta prefers, however, is to create a surveillance state defined by expensive scarcity. In the 1950s and 1960s, California’s legislature approved and implemented what remains the finest system of inter-basin water transfers in the world. But today, after over 30 years of neglect, at the same time as California’s population has doubled, California’s water infrastructure is crumbling at a time when it should be expanded. The reasons for this are plain enough. Special interests have replaced the public interest.

THE SCARCITY PROFITEERS

Instead of building water infrastructure to increase supplies of water, public employee unions want to see tax revenues pour into their pockets and into the pension funds. High-tech billionaires want contracts to build “smart” appliances and monitoring systems to enforce water rationing. Extreme environmentalists, and the trial lawyers who get incredibly wealthy representing their organizations, want more legal bases upon which to file lucrative lawsuits. Sadly, major corporate agribusinesses often acquiesce to this abuse of residents because they’ve decided that a bigger slice of a smaller pie is all they can hope for from this legislature.

Until Californians realize there will be no end to these encroachments on their freedom and prosperity until they resist, California’s ruling junta will prevail. California will be a harder and harder place to live. If ordinary Californians value their freedom, they will form a coalition with farmers, energy companies, civil engineering firms, and construction unions to demand water abundance. They may rediscover the vision and leadership that built a water infrastructure that is still one of the wonders of the modern world.

The Politics of Residential Water Pricing

California’s consumers already endure tiered rates for electricity consumption, where if their electricity consumption goes beyond approved levels, they pay more per kilowatt-hour. At least with electricity, there is some rationale for tiered pricing, because when demand exceeds capacity the utility has to purchase power from the grid at the spot market rate. But in the case of water that’s a much harder case to make. Water prices are negotiated far in advance by water utilities.

The reason utilities want to charge tiered rates is so they can discourage “over-consumption” of water, in order for them to avoid running out of water during times of severe drought. What happened repeatedly over the past few years was that suppliers to many regional water districts could not meet their contracted delivery obligations. Understandably, water districts want to reduce total annual consumption so, if necessary, they can get by with, for example, only 60% of the amount of imported water they would otherwise be contractually entitled to.

Punitive rates for “overuse,” however, will effectively ration water, as only a tiny minority of consumers will be wealthy enough to be indifferent to prohibitively high penalties.

There is a completely different way for water districts to address this challenge. An optimal solution to California’s water supply issues should incorporate not only conservation, but also increasing supply. And to fund new supplies of water, utilities should experiment with tiered pricing that only incorporates moderate price increases. Doing this would mean a large portion of consumers will not be deterred from “overuse,” and the extra revenue they provide the utility could be used for infrastructure investment to increase supplies of water through myriad solutions – including runoff capture and enhanced aquifer storage, sewage treatment to potable standards, seawater desalination, and off-stream reservoir storage.

The following images excerpted from a spreadsheet provide a simplistic but illuminating example of how reasonable tiered pricing could, in aggregate, fund massive investment in additional supplies of water. In the first example, below, with assumptions highlighted in yellow, are water consumption profiles for a regional water utility district that engages in punitive pricing for overuse of water. As can be seen in the large yellow highlighted block to the center left, when unit costs for water are tripled for those consumers who “overuse” water, the number of “over-users” is a small 4% minority of all consumers, and the number of “super-users” is a minute 1% of all consumers. Consequently, the utility only collects $900,000 per month, barely 5% of its revenue from consumers, from households that are deemed to have overused water.

Financial Impact to Utility of Punitive Pricing for “Overuse”

The next example, below, shows hypothetical consumption profiles for a regional water utility district that engages in reasonable pricing for overuse of water. Again, as can be seen in the the large yellow highlighted block to the center left, when unit costs for water are increased by 50% (instead of 300%) for those consumers who “overuse” water, the number of “over-users” is a significant 20% minority of all consumers, and the number of “super-users” is a substantial additional 10% of all consumers. Consequently, the utility collects $3,000,000 per month, 14% of its revenue from consumers, from households that are deemed to have overused water.

Financial Impact to Utility of Reasonable Pricing for “Overuse”

This is a simplistic analysis, requiring caveats too numerous to mention. Utilities get much of their revenue from property taxes, not from consumer ratepayers, and fixed service fees still constitute most of the amount that appears on a typical household water bill. The utility’s internal cost for water, pegged here at $.20 per CCF, is actually calculated through a maddeningly complex and somewhat subjective cost-accounting exercise that takes into account the amortization of capital costs for treatment, storage and distribution facilities, operating costs, as well as actual contracted purchases from, for example, the California State Water Project. But there is a deeper debate over principles that these examples are designed to emphasize, one with profound consequences for our quality of life in the coming decades.

By implementing severe financial penalties to utility customers who “overuse” their water, electricity, or anything else, state regulators are effectively imposing rationing on all but extreme high-income households. Complying in the face of punitive rates for overuse requires consumers to submit to undesirable lifestyle adjustments including short duration, low-flow showers, low flow faucets that require long wait times for hot water to arrive through the pipes and long wait times to fill pots, remotely administered, algorithmically managed “affordable” times for washing dishes and laundry, mandated purchases of expensive new internet enabled appliances that are ridiculously difficult to simply turn on and use, require regular warranty payments because they break down so much, with annual fees imposed to update their software.

We don’t have to live this way. California’s residential households consume less than 6% of the water diverted and used in California for environmental, agricultural, and commercial purposes, yet by far they pay the most to maintain and upgrade this infrastructure. Indoor water overuse is a myth, as all indoor water is either being completely recycled by the sewage treatment utility, or should be. Raising rates causes consumers to under-use water, despite most of a utility’s costs being for the operations infrastructure, creating a vicious cycle of rate increases to maintain sustainable revenues. And when consumer water use is crammed down further and further, the overall system of water infrastructure is progressively downsized until there is not enough resiliency and overcapacity in the system to absorb a major disruption such as an earthquake, a dam failure, or acts of terrorism.

The conventional wisdom in California as expressed in policies enforced by an overwhelming majority of Democrats in the State Legislature is that we must live in “an era of limits.” But this motto, originally coined in the 1970’s by Governor Jerry Brown, is in direct conflict with the spirit and culture of Californians, as exemplified by the dreams they offer the world from Hollywood and the miraculous innovations they offer the world from Silicon Valley. The idea that California’s legislators cannot enact policies designed to increase supplies of water and energy enough to make life easier on the citizens they serve is absurd, and must be challenged.

Desalination Plants vs. Bullet Trains and Pensions

Current policy solutions enacted to address California’s water crisis provide an object lesson in how corruption masquerading as virtue is impoverishing the general population to enrich a handful of elites. Instead of building freeways, expanding ports, restoring bridges and aqueducts, and constructing dams, desalination plants, and power stations, California’s taxpayers are pouring tens of billions each year into public sector pension funds – who invest 90% of the proceeds out-of-state, and the one big construction project on the table, the $100B+ “bullet train,” fails to justify itself under virtually any credible cost/benefit analysis. Why?

The reason is because infrastructure, genuinely conceived in the public interest, lowers the cost of living. This in-turn causes artificially inflated asset values to fall, imperiling the solvency of pension funds – something that would force them to reduce benefits. Beneficial infrastructure is also a threat to crony capitalists who don’t want a business climate that attracts competitors. Affordable land, energy, and water encourage economic growth. Crony capitalists and public sector unions alike hide behind environmentalists, who oppose growth and development, all of it, everywhere – because no new developments, anywhere, suits their monopolistic interests. No wonder the only infrastructure vision still alive in California, the “bullet train,” is nothing more than a gigantic, tragic farce.

Urban Water Consumption is a Small Fraction of Total Water Use

Returning to the topic of water, a basic examination of the facts reveals the current drought to be a problem that could be easily solved, if it weren’t for powerful special interests who don’t want it to be solved, ever. Here’s a rough summary of California’s annual water use. In a dry year, around 150 million acre feet (MAF) fall onto California’s watersheds in the form of rain or snow, in a wet year, we get about twice that much. [1] Most of that water either evaporates, percolates, or eventually runs into the ocean. In terms of net water withdrawals, each year around 31 MAF are diverted for the environment, such as to guarantee fresh water inflow into the delta, 27 MAF are diverted for agriculture, and 6.6 MAF are diverted for urban use. [2] Of the 6.6 MAF that is diverted for urban use, 3.7 MAF is used by residential customers, and the rest is used by industrial, commercial and government customers. [3]

Put another way, we divert 65 million acre feet of water each year in California for environmental, agricultural and urban uses, and a 25% reduction in water usage by residential customers will save exactly 0.9 million acre feet – or 1.4% of our total statewide water usage. One good storm easily dumps ten times as much water onto California’s watersheds as we’ll save via a 25% reduction in annual residential water consumption.

California’s politicians can impose utterly draconian curbs on residential water consumption, and it won’t make more than a small dent in the problem. We have to increase the supply of water.

Desalination is An Affordable Option

One way to increase California’s supply of fresh water is to build desalination plants. This technology is already in widespread use throughout the world, deployed at massive scale in Singapore, Israel, Saudi Arabia, Australia, and elsewhere. One of the newest plants worldwide, the Sorek plant in Israel, cost $500 million to build and desalinates 627,000 cubic meters of water per day. [4] That means that five of these plants, costing $2.5 billion to build, could desalinate 1.0 million acre feet per year. And since these modern plants, using 16″ diameter reverse osmosis filtration tubes, only require 5 kWh per cubic meter of desalinated water, it would only require a 700 megawatt power plant to provide sufficient energy to desalinate 1.0 million acre feet per year. [5] Currently it takes about 300 megawatts for the Edmonston Pumping Plant to lift one MAF of water from the California aqueduct 1,926 ft (587 m) over the Tehachapi Mountains into the Los Angeles basin. And that’s just the biggest lift, the California aqueduct uses several pumping stations to transport water from north to south. So the net energy costs to desalinate water on location vs transporting it hundreds of miles are not that far apart. [6]

The entire net urban water consumption on California’s “South Coast” (this includes all of Los Angeles and Orange County – over 13 million people) is 3.5 MAF. [7] Desalination plants with capacity to supply 100% of the urban water required by Los Angeles and Orange counties would cost under $10 billion, and require 2.5 gigawatts of electric power. These power stations could also be built for under $10 billion. [8]

Imagine that. For $20 billion in capital investment we could provide 100% of the fresh water required by nearly all of Southern California’s urban water users. For around $50 billion, 100% of California’s urban water requirements, statewide, could be financed – the desalination plantsand the power stations.

California’s taxpayers are currently condemned to shell out at least 500 billion dollars over the next 20-30 years so a train that hardly anyone will ride will careen through expropriated land, and pension funds can invest 90% of their assets out-of-state so public sector employees can retire 10-15 years early with pensions that are 3-5 times greater than Social Security. For less than one-tenth of that amount, we can solve our water crisis by investing in desalination. Why not, environmentalists? We’re willing to carpet the land with solar farms, exterminate raptors with the blades of wind turbines, and incinerate the rain forests to grow palm oil – all financed by selling carbon emission permits. Why not disburse brine offshore, where the California current will disburse it far more efficiently than any desalination plant situated on the Mediterranean Sea?

Another way to solve California’s urban water crisis is to recycle 100% of indoor water. Quaternary treatment, where water from sewage is purified and sent back upstream for reuse, is another proven technology already in limited use throughout California. In theory, not one drop of indoor water use can be wasted, since all of it can be reused.

And, of course, imagine how quickly California’s water crisis could be solved if farmers could sell their water allotments to urban water agencies. As it is, myriad restrictions largely prevent them from exercising this option, even though many of them could profitably sell their water allotments and make more than they make farming the crop. Do we really need to grow rice in the Mojave desert to export to China?

Environmentalists alone are not powerful enough to stop Californians from acting to increase water supply. Powerful government unions, pension funds, and anti-competitive corporate interests all have a stake in perpetuating artificial scarcity and authoritarian remedies. It suits them because it consolidates their power, and ensures they get a bigger slice of a smaller pie.
