East County Advanced Water Program Hits Multiple Milestones  

Work on the East County Advanced Water Purification Program facilities and pipelines reached multiple milestones at the start of 2024, and construction continues on schedule at multiple East County locations through 2025. As soon as 2026, the AWP will deliver water to the faucets of customers in the Padre Dam Municipal Water District, Helix Water District, Lakeside Water District service areas, and the northern portion of the Otay Water District service area.

At the main construction site north of Santee Lakes, more than 60% of the concrete has been poured for the water recycling, solids handling, and advanced water purification facilities. Nearly 60% of the 2.3 total miles of open-cut construction on wastewater pipelines that make up the AWP Program are complete.

In addition, pipeline work at Santee Lakes is occurring between Lakes 3 and 4. There is a road closure and no parking in some areas. The Kiwanis Playground at Lake 4 remains open and parking has been preserved for playground visitors.

“Roughly a year and a half ago, we started with a blank slate and since then, the Joint Powers Authority and its project partners have made significant achievements at each of the construction sites,” said Mark Niemiec, director of the East County AWP. “It’s during these ongoing activities within the community including at Santee Lakes that we really appreciate our neighbors’ patience and understanding.”

The wastewater pipelines that will run from the East Mission Gorge Pump Station near State Route 52 to the first lake at Santee Lakes will soon be pulled underground. This trenchless construction method called “Horizontal Directional Drilling” minimizes the impacts to nearby waterways, including the San Diego River. The process takes an estimated 24 to 36 straight hours.

Elsewhere, Fanita Parkway will be temporarily closed for up to one week in March between Ganley Road and Lake Canyon Road to allow for paving on both sides of the street. Residents will see detour signs prior to the closure. The road closure will occur during the day from 7 a.m. to 5 p.m.

Purified water pipeline construction is continuing west on Mast Boulevard in Santee, as well as west on Mapleview Street in Lakeside and from Laurel Canyon Road to El Monte Road. Lane closures can be expected.

Construction on the 23,000-square-foot Visitors Center is in progress and will be completed by the end of 2025. It will house administrative offices, the operation control center, a testing laboratory, and a community room. The steel beam installation, including 66 columns and 100 beams, will use 350,000 pounds of U.S. steel.

The Flume Trail at Lake Jennings is officially back open following a 10-month closure for purified pipeline construction. The trail will close again during the summer for a couple of months to allow for additional pipeline construction near the shoreline.

Colorado River Shortages Drive Major Advances in Recycled Sewage Water Use

After more than two decades of drought, water utilities serving the largest urban regions in the arid Southwest are embracing a drought-proof source of drinking water long considered a supply of last resort: purified sewage.

Water supplies have tightened to the point that Phoenix and the water supplier for 19 million Southern California residents are racing to adopt an expensive technology called “direct potable reuse” or “advanced purification” to reduce their reliance on imported water from the dwindling Colorado River.

“[Utilities] see that the river is overallocated, and they see that the climate is changing,” said Kathryn Sorensen, former director of Phoenix Water Services Department. “They’re looking at this and understanding that the river supply is highly variable and extremely uncertain in the future.”

The Colorado River that sustains nearly 40 million people and more than 4 million acres of cropland across seven states is shrinking because of climate change and overuse. The river’s flows have declined approximately 20 percent over the past century, and a more than two-decade drought that began at the turn of this century has pushed the system to its limits.

With so much at stake, cities dependent on the river are strengthening water conservation measures and pursuing new sources of water with urgency.

Olivenhain Municipal Water District Marks Milestone Recycled Water Anniversary

Water recycling reduces the need to import or develop additional drinking water supplies. It is a vital water management strategy to ensure a safe, reliable, and locally controlled water supply to support healthy environments, robust economies, and high quality of life.

Water and wastewater agencies in San Diego County are developing or expanding their water recycling infrastructure. Among those at the forefront is the Olivenhain Municipal Water District. OMWD marks a significant milestone in August: the 20th anniversary of its award-winning 4S Ranch Water Reclamation Facility, which began serving high-quality recycled water for irrigation in August 2003.

OMWD annexed the 4S Ranch and Rancho Cielo Sanitation Districts from the County of San Diego in 1998. OMWD also took ownership of a small wastewater treatment facility in 4S Ranch. This facility had the capability to treat 0.25 million gallons per day (MGD) of wastewater from the surrounding commercial center and condominium complex. Treated wastewater was disposed of by spraying it on nearby unimproved pastures.

Recognizing the significant development plans for the 4S Ranch area, OMWD expanded the capacity of the facility to 2.0 MGD. As part of this expansion, OMWD also incorporated additional treatment phases of filtration and ultraviolet disinfection, improving water quality. OMWD required area developers to install the entire recycled water infrastructure for their planned communities.

Today, the facility produces over one million gallons of recycled water per day. It is delivered to irrigation customers in the southeastern portion of OMWD’s service area for use at HOA common areas, schools, parks, streetscapes, and golf courses. Together with recycled water purchased from nearby water and wastewater agencies to serve customers in portions of Encinitas and Carlsbad, OMWD now serves up to 15 percent of its customers’ total water demand with recycled water.

“For 20 years, OMWD has proudly served 4S Ranch and neighboring communities with high-quality recycled water, reducing the use of drinking water for irrigation,” said OMWD Vice President Matthew Hahn. “As California continues to face water supply challenges, the expansion of our recycled water system strengthens our water supply reliability and promotes sustainable water management.

Water recycling is the process of capturing and treating wastewater, for non-domestic purposes such as irrigation and industrial processes.

Water and wastewater agencies across San Diego County are developing or expanding their recycled water systems to reduce the need to import or develop other supplies.

Since 2003, OMWD has significantly increased its recycled water purchases through connections with neighboring agencies, including the City of San Diego, San Elijo Joint Powers Authority, Rancho Santa Fe Community Services District, and Vallecitos Water District. OMWD now serves over two and a half million gallons of recycled water every day. Each year, OMWD installs additional recycled water pipelines and converts more customers from potable water to recycled water.

By 2027, the volume of recycled water produced in the U.S. is projected to increase 37% from 4.8 billion gallons per day to 6.6 billion gallons per day, according to a recent survey by Bluefield Research.

OMWD leadership in developing water recycling

As a founding member of the North San Diego Water Reuse Coalition, OMWD works with nine northern San Diego County water and wastewater agencies across jurisdictional boundaries to reduce the impact of water supply shortages on San Diego County’s $268 billion economy. This regional approach has proven successful in developing local projects as well as obtaining $9 million in funding, significantly reducing the costs of water recycling projects for North San Diego County water ratepayers.

In addition, the Coalition has also secured federal funding of $23.8 million to help cover costs for water reclamation projects through 2025.

Expanding capacity for the future

As it looks forward to the next 20 years, OMWD continues to expand its recycled water capacity. It began construction this summer on three recycled water pipelines near Calle Barcelona in Carlsbad and in Village Park in Encinitas. Once complete, OMWD can convert up to 27 meters to recycled water, offsetting 12.7 million gallons of potable water used annually for irrigation.

OMWD has long pursued alternative water supplies like recycled water, a reliable, drought-proof approach for complementing existing water sources.

The San Diego County Water Authority has supported the development of recycling projects for decades, through membership in groups such as the WateReuse Association and collaborative efforts to promote local reuse efforts. Approximately 35,000 acre-feet of recycled water is beneficially reused within the Water Authority’s service area annually, and the volume is expected to continue growing as new and expanded plants come online.
