Permit terms Might Kill Poseidon Desalination Proposal in Huntington Beach

Recommended terms for a permit to build Poseidon Water’s controversial desalination plant in Huntington Beach would make it impossible to get financing for the $1.4 billion project, according to the developer.

Drought: Why Water Supply Diversity is Critical

Drought is back in California. Federal and state agencies are warning of potential water shortages in the months ahead. Because of investments made by the San Diego County Water Authority, its member agencies and the region’s water ratepayers, San Diego County is safe from the threat of multiyear droughts.

“We are now facing the reality that it will be a second dry year for California and that is having a significant impact on our water supply,” said DWR Director Karla Nemeth in early April. “The Department of Water Resources is working with our federal and state partners to plan for the impacts of limited water supplies this summer for agriculture as well as urban and rural water users. We encourage everyone to look for ways to use water efficiently in their everyday lives.”

The San Diego region relies far less on supplies from Northern California than in previous decades. A severe drought in the early 1990s forced the region to confront the fact that continuing to provide safe and reliable water demanded a diverse portfolio of supplies instead of near-total reliance on a single source.

“We have sufficient water supplies whether it’s a normal year, which means normal rainfall,” said Jeff Stephenson, water resources manager at the San Diego County Water Authority. “A single dry year. Or a period of five straight dry years. Under those scenarios we have more than sufficient water supplies to meet the needs of the region.”

Investments and planning pay off

Stephenson credits three decades of efforts by the Water Authority and its 24 member agencies to diversify water sources, including contracts for water transfers with the Imperial Irrigation District and the Claude “Bud” Lewis Carlsbad Desalination Plant, as well as the development of additional water storage capacity in the region.

There are also several water reuse or recycling projects in development throughout San Diego County. The region’s dependence on imported water supply will decrease as these local supply sources are developed and become operational.

Approximately 43,000 acre-feet of recycled water is expected to be reused within the Water Authority’s service area annually by 2025. As the new and expanded potable reuse plants come online, they are projected to produce more than 112,000 acre-feet per year of new drinking water supplies by 2045, enough to meet nearly 18% of the region’s future water demand.

“Our member agencies throughout the region have developed more local supplies, such as recycled water,” Stephenson said. “In addition, the member agencies are developing potable reuse projects, including the city of San Diego’s pure water program which comes online in the future, and all of those supplies really make the region much more able to withstand drought periods.”

Revised drought contingency plan

As a result of the persistent drought conditions, and in accordance with its permit for the long-term operation of the State Water Project, DWR has submitted a revised Drought Contingency Plan to the California Department of Fish and Wildlife. The plan provides updated hydrologic conditions and outlines areas of concern for the joint operations of the State Water Project and the Central Valley Project, water quality, and environmental impacts.

In late-March, the State Water Resources Control Board mailed approximately 40,000 notices to water right holders, warning of persisting dry conditions and asking them to plan for potential shortages. Officials said the warnings, a result of two years of below average precipitation and below average state reservoir levels, will prompt early action to help minimize short term drought impacts.

“Planting crops and other decisions that are dictated by water supply are made early in the year, so early warnings are vital,” said Erik Ekdahl, deputy director for the Water Board’s Division of Water Rights. “These letters give water users time to prepare and help minimize the impacts of reduced supplies on businesses, farms and homes.”

The agency suggested in the letter that agricultural water users can implement practical actions now to improve their drought resilience, including reducing irrigated acreage, managing herd size, using innovative irrigation and diversifying water supply portfolios. Urban water users can conserve by putting in drought-resistant landscape, reducing outdoor irrigation and replacing older house fixtures and appliances with more efficient ones.

Increasing local supply sources

The San Diego County Water Authority and its member agencies continue to increase local supply sources and make investments to ensure a plentiful, safe, and reliable water supply for the region’s 3.3 million people and its $245 billion economy.

“Current conditions are a reminder of why the Water Authority and its member agencies have invested in locally controlled water sources and facilities such as dams and pipelines that can move water when and where it’s needed,” said the Water Authority’s Stephenson.

Ever since the drought of the early 1990s, the San Diego County Water Authority and its 24 member agencies have been leading advocates for water-smart strategies such as low-flow toilets, low-water landscapes and other conservation tactics. One result is that per capita water use in the San Diego region is down by more than 50% over the past three decades.

Water World: After Nearly 40 years, Peter MacLaggan Leaves a Liquid Legacy

Every time someone turns on the tap in San Diego County, out flows the work of Peter MacLaggan.

MacLaggan was the point man in the construction of the Carlsbad desalination plant, a nearly $1 billion public-private partnership that since 2015 has supplied nearly 10 percent of the potable water consumed in the county.

Desalination relies on the virtually unlimited supply of water in the Pacific Ocean. It provides a safe, reliable source of local water in a region that for many years relied on supplies from hundreds of miles away and was subject to mechanical breakdowns, seasonal shortages and the whims of nature.

Opinion: Newsom Right to Boost Huntington Beach Desalination Facility

Opponents of a proposed desalination facility along the Huntington Beach coastline are aghast that Gov. Gavin Newsom has taken steps to help end a years-long regulatory logjam. Although an environmentalist, the governor clearly recognizes the importance of developing new water sources to meet California’s needs. Privately funded facilities plants that turn saltwater into drinking water aren’t the only solution to California’s water shortages, but they are one solution. For instance, a similar plant in Carlsbad has the capacity to meet 9 percent of San Diego County’s water needs.

Opinion: San Diego’s Successful Desal Plant Should Be a Model for California Water Policy

Often the value of a plan or project can best be judged by its opposition. In the case of the proposed Poseidon desalination plant in Huntington Beach, the forces lined up against it are clear indicators that it’s a worthwhile enterprise.

Newsom Pushes Private Seawater Desalting Plant Over Local and Environmental Opposition

When Gov. Gavin Newsom was photographed dining at an opulent Napa Valley restaurant during a surge in coronavirus cases, many Californians saw it as hypocrisy. For opponents of a planned $1-billion desalination plant along the Orange County coast, however, the optics were menacing.

The unmasked Newsom was celebrating the birthday of a lobbyist for Poseidon Water, which is close to obtaining final government approval for one of the country’s biggest seawater desalination plants.

City of Antioch Breaks Ground on Water Project in Delta

On Friday,  the City of Antioch, along with local and State dignitaries, broke ground on their new and historic Brackish Water Desalination Plant. At a price of $110 million, the project was made possible with $93 million in funding from the State, and $17 million from the City of Antioch.

“Through this project, Antioch continues establishing itself as both a State and regional leader on environmental best practices,” said Lamar Thorpe, Mayor, City of Antioch. “I would like to thank Governor Newsom for California’s investment in making our Brackish Water Desalination Plant a reality. By working together, we exemplify the very best of our State and our City.”

Carlsbad Sand Dredging Project Protects Beaches, Water Supply

Heavy equipment will dominate a stretch of Carlsbad’s beach near the old Encina Power Plant for the next month.

Crews are funneling thousands of cubic yards of sand per day onto the beach, not only to protect the shoreline, but also the water supply.

Poseidon Water, which runs the desalination plant adjacent to the old power plant is running the project. The desalination plant converts 50 million gallons of ocean water to drinking water per day, providing 10 percent of the region’s water supply.

Regulators on Poseidon Desalination Plant Received Calls that are Likely Prohibited

Three members of the regulatory board considering approval of the controversial Poseidon desalination plant were called by the state’s environmental protection secretary at the time of last summer’s deliberations, an apparent violation of a rule that in serious cases can disqualify members from voting on the issue.

Opinion: Marin Voice – Advanced Metering, Desalination Would Bolster Water Supply Amid Construction Mandates

Samuel Coleridge’s poem “The Rime of the Ancient Mariner” features the phrase, “Water, water, every where, nor any drop to drink.”

Unlike the Ancient Mariner who was trapped on a salt-water ocean without fresh water, we in Marin County have fresh water surrounded by a salty bay and ocean.
