Opinion: Why Desalination Can Help Quench California’s Water Needs

If you’ve ever created a personal budget, you know that assigning your money to different investment strategies is a crucial component to meet your financial goals. When you stop dipping into your savings account each month, savings can begin to build.

Understanding why desalination is so critical to California’s water future is a lot like building a personal budget. With a changing climate, growing population and booming economy, we need to include desalination in the water supply equation to help make up an imported water deficit.

The California Natural Resources Agency, California Environmental Protection Agency and Department of Food and Agriculture recently released the Water Resilience Portfolio. In it, officials highlighted the importance of diversifying water supplies through the introduction of new water sources and preparing for new threats, including more extreme droughts.

UC Merced Researchers Working on Innovative Way to Desalinate Ag Water

MERCED, Calif. (KFSN) — A new project at UC Merced is focusing on irrigation water.
The work could have a significant impact on the crops that are grown throughout the Central Valley.

“We’re trying to take two problems and come up with one solution out of the two of them. We have an excess of drainage water which has excess salt in it, and we need cooling of agricultural greenhouses,” says assistant professor James Palko.

Desalination Emerges as a Possible Solution for Another Monterey County Water Challenge

On par with mission architecture or cattle ranching is another consequential relic of Spanish colonialism in California: the idea that water pumped from underground belongs to whoever owns the land above.

In the Central Valley, a major danger of unregulated pumping has been a drooping of the surface at a rate of one foot a year. Here, in the Salinas Valley, so much freshwater has been extracted that, in some aquifers, the natural flow from continent to ocean has reversed – seawater is pushing through gravel and sand into groundwater sources, threatening to spoil a critical household and agricultural supply.

Not Sports Podcast: San Diego Water Authority Board Chair Jim Madaffer

Darren Smith: Joining us now in studio is San Diego County Water Authority Board Chair Jim Madaffer.

Smith: “I think some of us we just turn on the shower in the morning and we use the faucet in our home and we never give a second thought as to what it’s coming and where it’s coming from, yet you have all the answers to these questions, don’t you?”

Jim Madaffer: “People do just turn on the faucet, the garden hose and they expect water to come out but yet a lot of folks don’t realize the incredible journey those molecules took to get to that faucet and what it takes to make sure they’re being delivered safe potable quality water and that it’s always reliable and at the best price possible.”

2019 In Review: Desalination Plans Stalled By Lawsuit

Plans to build an ocean desalination plant by West Basin Municipal Water District have been percolating for years.

The past year saw the completion of an Environmental Impact Report for a proposed facility in El Segundo that would generate 20 million gallons of freshwater daily from the salty ocean. Conservationists opposed to the technology say it’s too energy intensive, pollutes the air and water, and would sidetrack ongoing water recycling and replenishment goals. The district, meanwhile, says it’s a prudent measure to ensure water needs are met in times of droughts or emergencies.

Water District Sued Over Desalination Plant Proposed For South Bay

An environmental organization has filed a lawsuit against the West Basin Municipal Water District over its November approval of a large seawater desalination plant proposed along the coast just north of Manhattan Beach’s border with El Segundo, alleging that the water district ignored significant environmental issues in its assessment of the project.

Rep. Mike Levin and San Diego County Water Authority Board Chair Jim Madaffer on November 6, 2019.

Rep. Levin Touts Bipartisan Efforts to Fund Water Supply Reliability

Rep. Mike Levin said California’s innovations and investments in water supply reliability and renewable energy are a model for the nation – and that the state’s efforts protect the environment while growing the economy at the same time.

Levin, an attorney and congressman from San Juan Capistrano, represents the 49th District, which includes, Encinitas, Carlsbad, Vista, Oceanside and a portion of southern Orange County.

He made his remarks November 6 during a Legislative Roundtable at the San Diego County Water Authority attended by water agency board members and staff, local civic and business leaders and Citizens Water Academy graduates.

Water supply reliability through supply diversification

“We need a diverse array of resources for water,” said Levin. “Water is a finite resource that we often take for granted.”

The Water Authority periodically holds Legislative Roundtables to hear about water-related issues in Washington, D.C. and Sacramento. More than 60 people attended the Wednesday event, asking Levin a variety of questions about water, energy and climate change.

In his first 11 months in office, he has sponsored and co-sponsored the following bills:

  • Border Water Infrastructure Improvement Act
  • Desalination Development Act
  • Water Recycling Investment and Improvement Act
  • Land and Water Conservation Fund Permanent Funding Act
  • Colorado River Drought Contingency Plan Authorization Act

Desalination Development Act introduced

Levin cited the Claude “Bud” Lewis Carlsbad Desalination Plant as an example of the “deep innovation” necessary to increase sustainability, referencing legislation he introduced to increase federal funding for desalination projects.

He introduced that legislation in July 2019 to raise the funding authorization in the Water Infrastructure Improvements for the Nation Act for desalination projects to $260 million.

Levin said his bill would help strengthen regional water supplies by supporting projects like the South Coast Water District’s Doheny Ocean Desalination Project and the City of Oceanside’s Mission Basin Groundwater Purification Facility Well Expansion and Brine Minimization Project.

California’s clean energy economy a ‘model for the nation’

He also said California has proven that a clean energy economy works to enhance environmental sustainability and jobs.

“We’re leading the way in California, and at the end of the day, we’ve developed a clean energy economy,” Levin said. “The state is a model for the country in how to protect the environment and grow the economy.”

Why Desalinating Water is Hard — and Why We Might Need To Anyway

In places like San Diego and Dubai, where freshwater is scarce, humans turn to machines that pull the salt out of seawater, transforming it into clean drinking water.

Doheny Desalination Plant Still On Track Despite Higher Cost Estimates

While projected cost increases to the proposed Doheny desalination plant drew concern from two South Coast Water District directors at a meeting Wednesday, the majority of the board took the updated analysis in stride and the district continues pursuit of the project.

The bottom line for the average residential customer is that the expected monthly bill increase is now $10 — a 9% hike — rather than the $5 to $7 estimated in a 2017 report. Three members of the five-member board appeared comfortable with the latest estimates.

Upgrade For Desalination Project As It Plans Private Note Placement

Poseidon Resources received a one-notch upgrade to BBB from Fitch Ratings ahead of plans to privately place a $45 million note to finance construction of a new intake system for its desalination plant in Carlsbad, California.

Bank of America Merrill Lynch won the right to purchase the three-year note, expected to close in November, according to sources close to the deal.
