For decades, farmers in California’s Kern County have turned to wastewater from oil production to help irrigate their crops during extended dry spells. The wastewater provides an alternative to groundwater, which has become increasingly scarce as farmers have pumped more than they could replenish.
Olivenhain Municipal Water District’s Recycled Water Pipeline Extension 153A was recognized September 10 as a 2020 Project of the Year by the San Diego and Imperial County Chapter of the American Public Works Association at its virtual awards event.
The pipeline extension connected the Surf Cup Sports youth soccer fields in San Diego to OMWD’s recycled water distribution system. By allowing Surf Cup to convert the irrigation of 55 acres of grass fields to recycled water, OMWD has reduced potable water demands for irrigation by up to 100 million gallons per year.
“OMWD’s board is honored to receive this award for a collaborative project, which expanded the use of recycled water while protecting the environment,” said OMWD Board Treasurer Larry Watt. “Additionally, state grant funding helped pay for the project, reducing costs for our ratepayers.”
The project involved the installation of 1,600 feet of 8-inch PVC pipeline that required specialized drilling and interagency cooperation to be completed. The pipeline needed to cross the San Dieguito River, causing design, permitting, and construction obstacles. OMWD’s design team used horizontal directional drilling to install the pipeline more than sixty feet below the river bottom.
Horizontal directional drilling reduces not only surface area damage, but also environmental impacts from construction site dust, making it less impactful to nearby habitat and communities than traditional excavation work.
OMWD worked with the California Department of Fish and Wildlife on a streambed alteration agreement to ensure the protection of fish and wildlife habitat. OMWD also worked with the U.S. Fish and Wildlife Service to protect nesting birds such as the federally listed clapper rail and barn owl.
By OMWD taking proactive steps, such as daily biological sweeps of the project and inspections of the trenchless process, there was no adverse impact to habitat or species in the project area.
Interagency cooperation was also required for the project. The property is served water by Santa Fe Irrigation District and owned by the City of San Diego. While SFID did not have nearby recycled water infrastructure, it wanted to provide Surf Cup fields with a drought-resilient water supply. The OMWD pipeline project meets that need. The San Diego City Council approved a permanent utility easement allowing crews to access the property.
California’s Department of Water Resources awarded $202,300 for the project in Proposition 84 funding, which is administered by water wholesaler San Diego County Water Authority through the Integrated Regional Water Management program. The San Diego IRWM Program supports collaborative water management to increase regional self-reliance throughout California.

Olivenhain Municipal Water District’s Recycled Water Pipeline Extension 153A was recognized today as a 2020 Project of the Year by the San Diego and Imperial County Chapter of the American Public Works Association at its virtual awards event.
San Diego is not well endowed with many freshwater sources to support its growing population, so some water experts are perplexed the city’s ignoring a self-replenishing local groundwater source that, though small in size, is safe from the threat of natural disasters and reliably recharged by the San Diego River.
Olivenhain Municipal Water District’s Recycled Water Pipeline Extension 153A was recognized recently as a 2020 Project of the Year by the San Diego and Imperial County Chapter of the American Public Works Association at its virtual awards event, according to a news release.
Expansion of the Pure Water Monterey recycled water project is the best option for the Monterey region to meet its future water supply needs. Unfortunately, California American Water Co., a private water supplier, is discrediting the project in the hopes of instead getting approval for their much more costly, oversized and environmentally harmful groundwater desalination project to be built in, around and through the city of Marina.
Pure Water Monterey is finally poised to make water available for the Monterey Peninsula, providing a new water supply source for the area while allowing a reduction in Carmel River water usage albeit at a considerably reduced rate to start than was expected.
Last weekend, Monterey One Water announced that it had completed a 1,000-acre-foot recycled water reserve in the Seaside basin and that California American Water could start extracting additional water from the basin equivalent to the amount of recycled water being pumped into the basin beyond the reserve.
Nine months after the Coastal Commission conducted its first hearing on California American Water’s proposed desalination project, commission staff has again recommended denial of the project in favor of a Pure Water Monterey expansion proposal.
On Tuesday, commission staff released a 154-page staff report essentially reiterating its previous arguments against the Cal Am desal project, including its relative cost, environmental impact and controversial nature. It touted the “feasible and environmentally preferable” recycled water project as a viable alternative in the Monterey Peninsula’s long-running attempts to develop a replacement water supply to offset the state ordered Carmel River cutback order.
Earlier this month Olivenhain Municipal Water District announced they began supplying locally produced recycled water to the Seagate Village Homeowner Association in Encinitas.
The project is a collaboration between OMWD and San Elijo Joint Powers Authority since 2014 to bring recycled water to the Village Park neighborhood. San Elijo Water Campus, located in Cardiff-by-the-Sea, uses a combination of sand filtration, microfiltration, and reverse osmosis to produce high-quality water for irrigation and industrial uses.
The City of Oceanside received an Award of Excellence during the WateReuse Association virtual conference in June 2020. Oceanside received the Recycled Water Agency of the Year for small systems, which recognizes an agency that has developed recycled water, on a significant level, as an alternative water source within their service area, regionally, or statewide.
The development of water reuse programs addresses a variety of challenges currently faced by the City. Today, Oceanside imports most of its water from the Sacramento Bay Delta and the Colorado River, both of which are hundreds of miles away. In order to gain greater water-independence, the Oceanside City Council set a goal of a 50% local water supply by 2030. After almost a decade of regional and local planning efforts, the City of Oceanside has developed a comprehensive water reuse program including expanding water recycling and advanced water purification. The planning efforts have taken place since 2010 and have laid the groundwork for the City’s recycled water and potable reuse programs.
“The City of Oceanside is proud to receive the Recycled Water Agency of the Year Award,” said Cari Dale, City of Oceanside water utilities director. “Our staff works hard to ensure the City continues to increase our local water supply reliability and provide multiple benefits to our residents and businesses by reusing our water resources to their fullest potential.”

The City of Oceanside has 1.2 miles of recycled pipeline that distributed nearly 70 million gallons (236-acre feet) per year. The distribution system currently supplies recycled water to the Oceanside Municipal Golf Course, Goat Hills Golf Course, and El Corazon Sport Complex.
Oceanside is currently expanding its recycled water system in two phases. Phase 1 will add approximately seven miles of distribution pipelines and approximately 10 miles of additional distribution pipelines will be added for Phase 2. Recycled water customers will include commercial users with significant irrigation demands for landscaping such as golf courses, HOAs, City parks, as well as industrial and agricultural customers.
The City is also pursuing an advanced water purification project called Pure Water Oceanside. The project will create between 3 to 5 million gallons a day of high-quality drinking water that is clean, safe, drought-proof, and exceptionally pure.
Purified water, like the water created through Pure Water Oceanside, starts with recycled water that is further treated through proven advanced water purification processes to create clean and safe drinking water. The water purification process uses state-of-the-art purification steps that replicates and accelerates nature’s natural recycling process. Scheduled to be completed by the end of 2021, Pure Water Oceanside will be the first operating advanced water purification facility in San Diego County.
Through the expansion of recycled water and the development of Pure Water Oceanside, Oceanside has demonstrated leadership, creativity, and persistence in the development of a comprehensive water reuse program. Oceanside is well on its way to meet the City Council’s goal of 50% local water supply by 2030. By 2023 33% of Oceanside’s water supply will be local, which will increase to 56% by 2030.
