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.

Work began on OMWD’s Manchester Avenue Recycled Water Project in summer of 2022. As of October 1, more than half of the total 6,884 feet of recycled water pipeline has been installed. Once complete, irrigation customers connecting to the pipeline will reduce demand for imported potable water by more than 10 million gallons every year.

Olivenhain Municipal Water District Receives Recycled Water Award

/in , /by

The Olivenhain Municipal Water District received the WateReuse Association of California’s 2022 award for Recycled Water Community Outreach. The award was presented at WateReuse’s annual conference in San Francisco.

OMWD’s community outreach campaigns are intended to educate customers on the importance of water use efficiency, new supply development, and water reuse as a means to address future water supply challenges. To this end, recycled water is a focal point for OMWD’s public outreach campaigns. The recycled water award is another recognition of Olivenhain’s collaborative efforts to increase local, sustainable water supply sources in the region.

Reducing imported water

“Every drop of recycled water used on our landscapes replaces a drop of imported drinking water,” said OMWD Board Secretary Bob Topolavac. “With the state now in its third consecutive dry year, it is more critical than ever to be promoting the benefits of recycled water to new potential users to expand the use of this sustainable water supply.”

WateReuse previously recognized OMWD as California’s Agency of the Year in 2005 and again in 2019. Since that time, OMWD has expanded its recycled water distribution system such that it now meets 14 percent of its demands with recycled water.

Water Reuse Coalition

Beyond its borders, OMWD encourages a regional approach to recycled water infrastructure. It is the lead agency of the North San Diego Water Reuse Coalition, a group of nine North County agencies that coordinate across jurisdictional boundaries to connect recycled water sources with demands. By working together on the North County Regional Recycled Water Project, these agencies expect to reduce potable water use by nearly 11 billion gallons per year by 2035.

Formed in 1990, the WateReuse Association is a nonprofit organization whose mission is to advance the beneficial and efficient uses of high quality, locally produced, sustainable water sources for the betterment of society and the environment through advocacy, education and outreach, research, and membership.

The East County Advanced Water Purification Program broke ground, marking an important milestone for the recycled water project in San Diego County.

Scheduled to be complete in 2026, the East County AWP will generate up to 11.5 million gallons per day of purified water— meeting approximately 30% of current drinking water demands for East San Diego County residents and businesses.

Program representatives, elected officials and water industry leaders gathered at the future site of the treatment facility in Santee to celebrate the East County AWP. The project will create a new, local, sustainable and drought-proof drinking water supply using state-of-the-art technology to purify East San Diego County’s recycled water.

Officials in attendance included representatives from the East County AWP Joint Powers Authority, San Diego County Water Authority, Bureau of Reclamation, Metropolitan Water District of Southern California and the U.S. Environmental Protection Agency.

Potable reuse projects

“In 2045, potable reuse projects are going to provide up to 20% of the water that we need here in San Diego County,” said San Diego County Water Authority General Manager Sandra L. Kerl. “This region has been excellent in its innovation and planning for water needs for the region and this project is just another step in that process. I want to congratulate everyone involved in this project in developing another drought-resilient supply for the region.”

Water supply reliability for San Diego County

Collaboration on new recycled water supply

The groundbreaking follows approval of project construction on May 19, 2022, by the East County AWP Joint Powers Authority that owns and operates the Program and is a collaborative partnership between four agencies: Padre Dam, the City of El Cajon, the County of San Diego and Helix Water District. The overall cost for the project is $950 million and estimated to create 2,500 jobs in the region.

The project will use four advanced water purification steps to produce water that is near-distilled in quality.

Sustainable source of water

“Today marks an exciting moment for our East San Diego County customers,” said Allen Carlisle, Padre Dam and JPA Administrator CEO/General Manager. “We are now one step closer to creating a local, reliable and sustainable drinking water source that will reduce our dependence on increasingly expensive imported water. The East County Advanced Water Purification Program is a smart investment that provides a long-term solution for increased stability in our communities and safeguards the vitality of our economy and quality of life.”

After the advanced water purification process, the purified water will be blended with water in Lake Jennings and treated again at Helix Water District’s R.M. Levy Water Treatment Plant before being distributed as drinking water.

New local supply

“In addition to providing a new local water supply, the Program will eliminate the need to send most of East County’s wastewater to the City of San Diego’s Point Loma Wastewater Treatment Plant, where it is currently treated and then discharged into the ocean,” said Kyle Swanson, Padre Dam Incoming CEO/General Manager. “The East County Advanced Water Purification Program will benefit not only our customers and the community, but our shared environment too.”

The East County AWP has secured more than $123 million in grant funding and up to $796 million in low interest loans to help finance the project. East County AWP officials anticipate receiving additional state and federal grant funding to help pay for the project.

Local leadership and vision

“As California adapts to an increasingly arid climate, expanding our water supply portfolio with 21st century investments in water recycling, like the East County Advanced Water Purification program is critical,” said Joaquin Esquivel, Chair, State Water Resources Control Board. “Thanks to state and federal leadership, we have a generational opportunity to support the affordability and viability of this and other water supply projects throughout the state. Local leadership and vision are what have made this project a reality and helped to show that we can turn climate anxiety into climate action.”

East County’s $950M Water Recycling Project Could be in Jeopardy as San Diego Nixes Pipeline Deal

/in , , /by /The San Diego Union-Tribuneby Joshua Emerson Smith

East County officials fear a $950 million sewage recycling project could get flushed down the drain because of a pipeline deal gone awry.

Leaders spearheading the endeavor blame San Diego Mayor Todd Gloria — who signed off on building an eight-mile “brine line” as recently as last year but has since reneged on that commitment.

The pipeline would prevent concentrated waste generated by the East County project’s reverse osmosis filtration system from entering into the city’s own $5 billion Pure Water sewage recycling project now under construction. Instead the byproduct would be routed into the city’s larger wastewater system.
