Residential customers of the Olivenhain Municipal Water District can get free recycled water through a program to conserve water and lower costs for consumers. According to the San Diego County Water Authority, “water recycling is the treatment and disinfection of municipal wastewater to provide a water supply suitable for non-drinking purposes.” Olivenhain produces recycled water by collecting wastewater from the 4S Ranch and Rancho Cielo areas, and processing it at the 4S Ranch Water Reclamation Facility in San Diego, the district states. The facility produces over one million gallons of recycled water per day, which is highly treated to meet irrigation standards.
Chula Vista, Calif. – On Wednesday, July 24, the Sweetwater Authority (Authority) Governing Board was presented with the Southwest Membrane Operators Association (SWMOA) Best Tasting Membrane Water in the Southwest Region Award. The award recognizes the Authority’s Richard A. Reynolds Desalination Facility as the winner of the Best Tasting Membrane Water Competition held during the SWMOA Annual Symposium in June.
Encinitas, Caif. – On July 26, Olivenhain Municipal Water District will re-open its recycled water fill station for the warm summer season, offering free recycled water to its residential customers.
OMWD operates the facility to help customers irrigate during San Diego’s warm season, minimizing potable water demands and assisting customers with lowering their higher summer bills. The fill station, located at Campania Avenue and Camino San Thomas in 4S Ranch, will open Fridays 11:00 a.m. to 5:00 p.m. and Saturdays 7:00 a.m. to 3:00 p.m.
Fifty feet below the platform of the Powell Street BART Station sits the starting point for one of the largest water recycling projects in San Francisco — one that’s transforming dirty groundwater into clean steam heat for hundreds of downtown buildings. In the process, it’s saving tens of millions of gallons of drinking water annually.
For decades, BART officials treated the naturally percolating groundwater that pools beneath the BART stop as a nuisance and a potential flooding risk. After seeping into an underground cistern, millions of gallons of water a month was pumped into the city’s sewer system.
The East County Advanced Water Purification Project is moving forward after a new funding agreement was approved.
The program’s partner agencies – Padre Dam Municipal Water District, the City of El Cajon, Helix Water District and the County of San Diego – recently approved the Interim Funding Agreement. The final vote from the County of San Diego took place July 10.
The project is expected to begin producing water in 2025.
Purified water reduces dependence on imported water
The agreement requires each agency to commit $2.35 million ($9.4 million total) toward the program, with the aim to 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.
“This is an important milestone toward the completion of this innovative and much-needed program, said Allen Carlisle, CEO and general manager of Padre Dam Municipal Water District. “Working together with our partners, we are moving one step closer to reducing our dependence on imported water and putting the mechanisms in place to support our economy and quality of life well into the future.”
Sustainable drinking water project
Once complete, the East County Advanced Water Purification Program will generate up to 11.5 million gallons per day of new drinking water. This represents approximately 30 percent of current drinking water consumption for residents within the Padre Dam service area (Santee, El Cajon, Lakeside, Flinn Springs, Harbison Canyon, Blossom Valley, Alpine, Dehesa and Crest), and the Helix service area (including the cities of Lemon Grove, La Mesa, and El Cajon, and the Spring Valley area). This represents approximately 373,000 residents.
The project will recycle East San Diego County’s wastewater locally, and then purify the recycled water at an advanced water treatment facility using four advanced water purification steps producing water that is near-distilled in quality. The purified water will then be blended with water in Lake Jennings, treated again at the Helix R.M. Levy Water Treatment Plant and then distributed into the drinking water supply.
Industry Day planned for prospective designers and contractors
Next steps for the project include formation of a Joint Powers Authority between Padre Dam Municipal Water District, the City of El Cajon, and the County of San Diego to serve as the governing body for the program.
An industry day is being planned in mid-August to provide notice to prospective designers and contractors on the initiation of a selection process for the progressive design-build packages that will begin posting in Fall 2019.
Partner agencies also continue to pursue grant and loan opportunities to help fund the estimated $528 million project.
The water-recycling project is intended to diversify East County’s drinking water supply and reduce the region’s dependence on imported water. It also helps the region in achieving long-term compliance with the Clean Water Act.

The City of San Diego held its third ‘Pure Water Day’ Open House at the North City Water Reclamation Plant in the Miramar area, inviting residents to enjoy family-friendly activities and learn about the upcoming project construction.
More than 300 people took tours of the five-step water purification process at the Pure Water Demonstration Facility and tasted the purified water produced at the facility following their tour. Residents of University City, Clairemont, and Scripps Ranch learned about Phase 1 of construction scheduled in their neighborhoods.
“We are excited to once again open our doors to the community, and share how we will deliver a new, safe, local source of drinking water for San Diego,” said John Helminski, assistant director of the San Diego Public Utilities Department.
Pure Water first phase starts construction later this year
Pure Water San Diego is a multi-year phased program using proven technology to clean recycled water to produce safe, high-quality potable water. After construction is completed, the Pure Water Program is expected to provide one-third of the City of San Diego’s water supply by 2035.
The first phase of construction includes the North City Pure Water Facility, new pump stations and pipelines, and upgrades to existing facilities. The North City Pure Water Facility will be constructed on City of San Diego owned property east of Interstate 805 and north of Eastgate Mall, across from the existing North City Water Reclamation Plant.
Purified water produced at the completed plant will be delivered to the Miramar Reservoir, blended with the City of San Diego’s imported and local water sources, and treated again at the existing Miramar Drinking Water Treatment Plant. After this process, the water will be distributed to customers. Construction of Phase 1 is expected to begin later this year and is scheduled for completion in 2023.
Encinitas, Calif.—American Public Works Association’s San Diego and Imperial Counties Chapter has recognized Olivenhain Municipal Water District’s Avenida La Posta Recycled Water Project as “Project of the Year.” The award, celebrating OMWD’s engineering and project management efforts, was presented yesterday at a reception at Paradise Point Resort in San Diego.
The WateReuse Association, California chapter named the City of Malibu the 2019 “Recycled Water Agency of the Year” for its Civic Center Water Treatment Facility (CCWTF), which was completed and started processing wastewater into clean, recycled water for irrigation in October, 2018. “The City of Malibu and its people have always defined themselves as innovators of environmental protections and programs,” said Mayor Jefferson “Zuma Jay” Wagner. “Our new water treatment facility puts us ahead of the curve of smart, environmentally sound water management practices while combating the realities of climate change and drought here in California.”
Encinitas, Calif. — Olivenhain Municipal Water District’s 4S Ranch Water Reclamation Facility was recognized today by California Water Environment Association as its 2019 Plant of the Year (Small). The award was presented during CWEA’s Annual Conference in Palm Springs and acknowledges OMWD’s efforts to increase water supply reliability by reducing imported water demand.
Olivenhain Municipal Water District (OMWD) was recognized late last month as the medium-sized Agency of the Year by the WaterReuse Association of California. The award honors OMWD’s development of local and regional recycled water resources that conserve potable water, as well as its leadership and its outreach to legislators, regulators, and large irrigators. OMWD was previously recognized by the WaterReuse Association in 2005 as the small-sized Agency of the Year for having significantly expanded its recycled water distribution system. That system is currently generating 14 percent of the district’s demands with recycled water.
