Protecting marine habitats

“Diversifying and stretching precious water supplies is essential in the water scarce West,” said EPA Assistant Administrator for Water Radhika Fox. “Our WIFIA loan to Poseidon Resources in San Diego County will be used for both upgrading the drinking water desalination plant to help address water shortages, stretch precious water supplies, and protect critical marine habitats in the San Diego Bay.”

WIFIA program and water infrastructure

Established by the Water Infrastructure Finance and Innovation Act of 2014, the WIFIA program is a federal loan and guarantee program administered by EPA. The WIFIA program’s aim is to accelerate investment in the nation’s water infrastructure by providing long-term, low-cost supplemental credit assistance for regionally and nationally significant projects.

The WIFIA program has an active pipeline of pending applications for projects that will result in billions of dollars in water infrastructure investment and thousands of jobs. With this WIFIA loan closing, EPA has announced 101 WIFIA loans that are providing $17 billion in credit assistance to help finance $37 billion for water infrastructure while creating 125,000 jobs and saving ratepayers over $5 billion.

Colorado River Board of California-River Board-Tour

San Diego County Water Authority Hosts Colorado River Board of California

The San Diego County Water Authority will host water leaders from throughout Southern California March 15 for the monthly meeting of the Colorado River Board of California. On March 14, before the formal meeting, CRB board members will tour projects in the region that promote water resiliency.

The CRB will consider the complex water supply issues facing the Southwest U.S. during its meeting. San Diego Congressman Scott Peters is also scheduled to address the CRB.

Colorado River Board of California

The tour is part of a new program implemented by CRB, under the leadership of Chair JB Hamby, Imperial Irrigation District’s representative, and Vice Chair Jim Madaffer, the Water Authority’s representative and Water Authority board member, to build greater awareness of each CRB member agency’s efforts to serve their region and manage their river supplies.

“The Colorado River Board is so important to ensuring California’s voice is heard on the river, especially during these difficult times as we work to find collaborative solutions to the river’s challenges now and into the future,” Madaffer said. “We look forward to showcasing the local supply projects, online now and planned, that create water resiliency locally, but that also reduce the demand on the river.”

Established in 1937, the CRB is a state agency tasked with protecting the interests and rights of the state and its agencies in water and power resources from the Colorado River.

The Water Authority is a member of the CRB along with IID, the Metropolitan Water District of Southern California, the Coachella Valley Water District, the Palo Verde Irrigation District, the Los Angeles Department of Water and Power, the California Department of Water Resources, and the California Department of Fish and Wildlife. CRB representatives, including two additional members from the public, are appointed by the Governor.

Management of the river

The CRB represents California in discussions and negotiations with the Basin states, the U.S. Bureau of Reclamation, governmental agencies at all levels, tribes, and Mexico regarding the management of the river.

CRB members on the tour will see two local water supply projects generating water now – the Claude “Bud” Lewis Carlsbad Desalination Plant – and planned – the East County Advanced Water Purification Plant.

Seawater desalination

The seawater desalination plant, the largest in the nation, came online in 2015 and recently passed the milestone of producing more than one-billion gallons of water for the San Diego region.

“The desalination plant is not only important to our region, but the Water Authority believes the plant could be part of an overall long-term solution to support Lake Mead, California’s critical river reservoir, under a proposal we are considering to expand the plant,” said Madaffer.

Water purification

Now under construction, the East County Advanced Water Purification facility, or East County AWP, is a collaborative partnership between two Water Authority member agencies, the Padre Dam Municipal Water District and the Helix Water District, and the County of San Diego and City of El Cajon.

The plant is projected to generate a local, reliable and drought-proof drinking water supply utilizing state-of-the-art technology to recycle and reuse the region’s wastewater. The East County AWP is expected to produce 30% of East San Diego County’s water supply by early 2026, and is one of the innovative water purification facilities in the county either in operation or in development.

Following the facility tours on March 14, the CRB will hold its monthly meeting March 15 at the Water Authority’s Kearny Mesa headquarters in San Diego. The meeting is scheduled to start at 10 a.m. and is open to the public.

(Editor’s note: The Helix Water District and Padre Dam Municipal Water District, are two of the San Diego County Water Authority’s 24 member agencies that deliver water across the San Diego County region.) 

Poseidon Deal Will Finance New Ocean Intake for Desalination Plant

The California Pollution Control Financing Authority plans to price $158 million in revenue bonds next week to pay for modifications to the seawater intake system for a San Diego County desalination plant.

The Claude “Bud” Lewis Carlsbad Desalination Plant was built by private operator Poseidon as a partnership that supplies water to the San Diego County Water Authority.

The plant, developed by Poseidon and operated by IDE Technologies, has produced more than 100 billion gallons of desalinated seawater since it opened in December 2015, providing San Diego County with 10% of its water supply each year, according to the preliminary limited offering memorandum.

Why Desalination Won’t Save States Dependent on Colorado River Water

States dependent on the drought-stricken Colorado River are increasingly looking toward desalination as a way to fix the river’s deficit and boost water supplies across the western U.S.

The search for alternative ways to source water comes as federal officials continue to impose mandatory water cuts for states that draw from the Colorado River, which supplies water and power for more than 40 million people.

State Water Project to Boost Deliveries from 5% to 30% of Normal After Rains

California’s giant State Water Project, the network of dams and aqueducts that provides water for 27 million people, will significantly increase deliveries in 2023 after a month of “atmospheric river” storms.

The Department of Water Resources announced Thursday that deliveries will increase from 5% of requested supplies to 30% for the water year than began Dec. 1.

Water Conservation Still Necessary for Carlsbad Residents

Though recent rains have helped, the city of Carlsbad is still striving to conserve water. The rains have helped, but conservation is still needed, according to the Carlsbad City Manager’s office.
