Carlsbad Desalination Plant Celebrates 100 Billion Gallons Served

/in , /by

Carlsbad, Calif. (Nov. 1, 2022) – The Claude “Bud” Lewis Carlsbad Desalination Plant has served more than 100 billion gallons of high-quality, locally controlled water over the past seven years – a milestone passed in late October, as California entered a fourth consecutive year of severe drought.

The plant produces an average of more than 50 million gallons of high-quality, locally controlled water every day. It’s a foundational water supply for the San Diego region that minimizes vulnerability to drought and other water supply emergencies. The facility is the largest, most technologically advanced and energy-efficient desalination plant in the nation, and it has provided a sustainable water supply to residents and businesses in San Diego County since December 2015.

“As we mark this achievement, water from the seawater desalination plant continues to reduce our dependence on imported water sources, which has the effect of making more water available for drought-stricken communities elsewhere,” said Mel Katz, Board chair for the San Diego County Water Authority. “Since coming online in 2015, the Carlsbad Desalination Plant has met nearly 10% of the region’s water demand, and it will be a core water resource for decades to come.”

The desalination plant is a key piece of the region’s multi-decade strategy to diversify its water supply portfolio. A 30-year Water Purchase Agreement between Poseidon (Channelside) LP and the Water Authority allows for the production of up to 56,000 acre-feet of water per year, enough to meet the needs of approximately 400,000 people.

Desalination uses reverse osmosis technology to remove water molecules from seawater. Water from the ocean is forced through tightly-wrapped, semipermeable membranes under very high pressure. The membranes allow the smaller water molecules to pass through, leaving salt and other impurities to be discharged from the facility.

“Reaching 100 billion gallons demonstrates the value, effectiveness, and reliability of the desalination plant, as it produces high-quality water to help meet the needs of the region’s residents and businesses,” said Channelside President, Sachin Chawla.

Water Recycling Projects Expanding in San Diego County

/in , /by

A proactive approach to developing diversified water sources, including water recycling projects and conservation efforts, are helping the San Diego region weather the current drought.

The Olivenhain Municipal Water District is working on multiple projects to expand the use of recycled water. The U.S. Bureau of Reclamation awarded the North San Diego Water Reuse Coalition, led by OMWD, $17.8 million in August for the development of recycled water infrastructure in North County.

Combined with the $6.1 million the federal agency granted to the coalition in 2021, up to $23.9 million will help cover costs for work performed on water reclamation and reuse projects through 2025. The coalition consists of nine water and wastewater agencies coordinating recycled water efforts across jurisdictional boundaries.

“Our board is proud to be a water district that consistently innovates to reduce project costs,” said OMWD Board Director Neal Meyers. “We constantly develop new funding partnerships, and we aggressively pursue grant funds to help build our vital infrastructure projects at the lowest possible cost to our ratepayers.”

Regional Recycled Water Project

The Regional Recycled Water Project will increase the capacity and connectivity of the recycled water storage and distribution systems of the coalition members and maximize reuse of available wastewater supplies.

To do this, the project will replace potable water uses with recycled water components, convert facilities to recycled water service, connect discrete recycled water systems to one another, increase recycled water storage capacity, and distribute recycled water to effectively meet recycled water demands.

Maximizing water reuse, increasing local supply

Project objectives include optimizing available wastewater resources to help offset demands for imported potable water; proactively planning for facilities to meet demands for existing and planned growth in member service areas; combining resources and working together to maximize water reuse; and increasing water supply availability, reliability, and sustainability.

When all long-term project elements are completed, North San Diego County will gain approximately 41 million gallons per day of recycled water and potable reuse water.

Pipeline 5-Shutdown-Shutdown Season-Asset Management

“Shutdown Season” for Regional Aqueducts in San Diego County

/in , /by

Sections of the regional aqueducts in San Diego County will be shut down over the next six months for maintenance projects to ensure a safe and reliable water supply for the region. The San Diego County Water Authority and its member agencies are coordinating on the annual “shutdown season” to minimize impacts to residents and businesses, who are not expected to face service disruptions.

Starting October 16, a portion of Pipeline 5 will be out of service for 10 days to accommodate annual maintenance on the entire untreated water system and to prepare for rehabilitation of other sections of the pipeline. The Water Authority has worked for months to coordinate with the affected retail water agencies: Olivenhain Municipal Water District, San Dieguito Water District, Santa Fe Irrigation District, Helix Water District, Sweetwater Authority, and the cities of San Diego, Oceanside, Ramona, Poway and Escondido. Customers should check with their water utility if they have questions about localized impacts.

Proactive asset management – regional aqueducts and Pipeline 5

The Pipeline 5 work will rehabilitate about 5,000 feet of 96-inch diameter prestressed concrete cylinder pipe by inserting and securing a steel pipe liner. This portion of the pipeline is within the City of San Marcos, between North Twin Oaks Valley Road and the Water Authority’s Twin Oaks Water Treatment Plant. When completed, approximately 50 miles, or 61% of the Water Authority’s existing prestressed concrete cylinder pipe will be relined.

“Proactive asset management and coordination with our member agencies ensures that the region’s major water infrastructure reliably serves the region’s 3.3 million residents,” said Eva Plajzer, the Water Authority’s director of operations and maintenance. “We have worked with our member agencies for several months to minimize any impacts to residents and businesses.”

Safe and reliable water supplies

The Water Authority’s Asset Management Program is a key element of providing safe and reliable water supplies to the region. The agency continually assesses and inspects its 310 miles of large-diameter pipelines, which provide treated and untreated water to 24 member agencies in San Diego County. The program is widely recognized for pioneering work – including a patented inspection device – that promotes water affordability by avoiding costly unplanned disruptions in service. Maintenance work is scheduled during low-demand periods to minimize impacts on water service.

Constructed in 1982, Pipeline 5 is a vital component of the Water Authority’s regional water infrastructure system, delivering untreated supplies from Lake Skinner in southwest Riverside County to the Lower Otay Water Treatment Plant in southern San Diego County.

In addition to the October upgrades on Pipeline 5, a series of three shutdowns on the Water Authority’s First Aqueduct is scheduled from December through April, when portions of the aqueduct will be relined, along with other maintenance.

(Editor’s note: The Olivenhain Municipal Water District, San Dieguito Water District, Santa Fe Irrigation District, Helix Water District, Sweetwater Authority, and the cities of San Diego, Oceanside, Ramona, Poway and Escondido are 10 of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)

Collaboration Key to Stabilizing Colorado River Basin Decline

/in , /by

Collaboration among all water users is key to developing solutions for the Colorado River Basin, which is in the midst of a 22-year megadrought. That was one of the common themes during a webinar Thursday, in which water managers and other officials discussed ways to slow or stabilize the rate of decline of the major source of water for seven states and Mexico.

“A Collaborative Approach to Colorado River Management,” was part of the Southern California Water Coalition‘s “What Matters” webinar series. The San Diego County Water Authority, Imperial Irrigation District, Black & Veatch, and Richard Brady & Associates sponsored the webinar.

Webinar participants:

  • Sandra Kerl, San Diego County Water Authority General Manager
  • Henry Martinez, Imperial Irrigation District General Manager
  • Adel Hagekhali, General Manager of the Metropolitan Southern California Water District
  • David Palumbo, Deputy Commissioner – Operations, U.S. Bureau of Reclamation
  • Thomas Tortez, Jr., Tribal Chairman, Torres Martinez Desert Cahuilla Indians
  • Michael Cohen, Senior Associate, Pacific Institute
  • Chris Harris, Executive Director, Colorado River Board of California

“Unprecendented” and “challenging times”

During the 90-minute discussion, speakers said that drought and climate change impacts on the Colorado River Basin have created “challenging times” and that “unprecedented times require unprecendented management” solutions. Solutions mentioned included sustainable conservation, additional storage, a reduction in demand, and inclusion of all users to ensure the long-term health of the river system.

The Water Authority’s supply portfolio includes high-priority, conserved Colorado River supplies negotiated through the landmark 2003 Quantification Settlement Agreement, or QSA. The conserved supplies are the cornerstone of the San Diego region’s long-term water supply diversification strategy.

Colorado River Basin: Voluntary reductions from California

The webinar came a day after California water agencies that use Colorado River water supplies, sent a letter to the U.S. Department of the Interior and U.S. Bureau of Reclamation, voluntarily offering to reduce their use of water from the river starting in 2023:

“Given dire drought conditions across the region and dangerously low reservoir levels, we firmly believe that all water users within the Basin must take immediate voluntary actions to stabilize water supplies in the Basin’s major reservoirs.

“California water agencies that utilize Colorado River water supplies propose to conserve up to an additional 400,000 acre-feet of water in Lake Mead each year, beginning in 2023 and running through 2026. This water, which would otherwise be used by California’s communities and farms, will meaningfully contribute to stabilizing the Colorado River reservoir system. While a broad multi-state agreement to conserve water across the Basin has not been reached, the California agencies propose to take voluntary action now to conserve water in coming months.”
