Environmental groups challenging the Carlsbad Desalination Plant scrutinize the project because as proposed it’s the region’s most expensive and energy intensive water supply option. As one of the environmental groups leading the charge in challenging the Carlsbad Desalination Plant, we’re clearing the air about a few misconceptions.
Truth #1 Our cases have merit.
Procedural deficiencies at every reviewing agency have marred the approval process for the plant. While some suggest we are engaging in superfluous lawsuits, this desalination plant will be the largest in the western hemisphere and may set precedent for all other projects. We must ensure it is as protective of our environment as possible. Yet, our regulatory agencies have taken an “approve first, ask questions later” approach that could lead to disastrous consequences.
Our efforts, and those of our partner organizations, have already improved the project dramatically by ensuring carbon offsets and wetlands mitigation to offset some impacts from the proposed project.
Truth # 2 We don’t oppose desalination.
We support a comprehensive water policy – prioritizing how we get and use our water based on cost, environmental and energy impacts, and reliability. First, we need to exhaust conservation and water efficiency efforts. After the City of San Diego instituted mandatory water use restrictions last year, outside water use dropped 13 percent. In a county where nearly 50 percent of our water goes to residential use (60% of that for landscape irrigation), conservation can provide huge savings.
Second, we need to aggressively pursue water reuse. The City of San Diego is currently exploring Indirect Potable Reuse, which recycles wastewater to drinking water standards above that of our current supplies. Rainwater harvesting, grey water and non-potable water reclamation provide other opportunities to access hundreds of millions of gallons of recycled water daily.
Both conservation and reuse are cheaper, more energy efficient than desalination and can dramatically reduce ocean pollution without killing fish in the process.
Truth # 3 Desalination is the most expensive way to enhance local water supplies.
Conservation saves consumers money by reducing water and energy bills. Augmenting local reservoirs with recycled water uses the same treatment technologies as desalination but at 40 percent of the cost. And while Poseidon continues to claim on its website that its project will be developed at no expense to taxpayers, the truth is the project will receive $350 million over the next 25 years in public Metropolitan Water District subsidies and has a pending $530 million request in tax-free Private Activity Bonds to finance the project.
Truth # 4 Desalination is also the most energy intensive water option for San Diego.
Estimates show that 19 percent of California’s energy usage is for the treatment, movement and delivery of water. Between 3 and 5 percent of the state’s energy is used simply to move water from northern to Southern California, but desalination requires more. It also uses one third more energy than recycling wastewater.
Truth #5 If it sounds too good to be true, it probably is.
We’ve been asked to stand aside and support public opinion. However few important battles (civil rights, environmental protection, etc.) have been won without taking unpopular positions. The project’s popularity is based on the allure of a seemingly inexhaustible ocean resource and the small fortune Poseidon has paid in public relations and lobbying efforts to promise everything to everybody: for San Diegans, an endless supply of cheap water; for taxpayer/consumer groups, a guarantee of no subsidies; for organized labor, good union jobs; and for environmental groups, full environmental mitigation (the company claims the plant will be a net benefit for wetlands and ocean habitat). Poseidon is San Diego’s real-life Santa Claus!
So, if you are asking yourself, “how does this add up?” you’re ahead of the folks that have approved the project to date. A better question may be, “why did so many appointed officials approve this project (almost always overruling staff recommendations) without asking these tough questions in the face of such obvious contradictions?”
This is the question we are trying to resolve through our challenges.
We all want the same thing for our region—a dependable, affordable and sustainable water supply. Rather than make decisions in a crisis, we’d like to see our region make strategic decisions that protect our citizens and environment from unnecessary costs and harm. That’s why we need to develop a more thoughtful, comprehensive water policy for the region that prioritizes lower-cost, lower-impact alternatives like conservation and efficiency and reclamation. Desalination should be a last resort in our water portfolio.
