4S Ranch Water Reclamation Facility Named 2024 Plant of the Year

/in , /by

The Olivenhain Municipal Water District’s 4S Ranch Water Reclamation Facility (4S WRF) was named the statewide 2024 Plant of the Year (small division) by the California Water Environment Association at its recent annual conference in San Diego. The award recognizes the facility’s innovation, regulatory compliance, and cost-effective operation.

In addition to being named California’s plant of the year, the facility received the same designation at the local level in February from CWEA’s San Diego Section.

The 4S Ranch Water Reclamation Facility is a repeat winner, winning this statewide recognition as Plant of the Year five times since 2019.

“There are over a thousand wastewater treatment plants in California, and our district is honored to have 4S WRF named as CWEA’s Plant of the Year at the state level for the second time in three years,” said Matthew R. Hahn, OMWD board president.

“The successful operation of the 4S WRF is a direct result of the support and collaboration across all areas of the District, including the Board of Directors, senior management, the 4S WRF operators, and all OMWD departments,” said John Onkka, Water Reclamation Facilities Supervisor at the 4S Water Reclamation Facility.

Innovation Drives High Quality, Saves Treatment Costs for Ratepayers

Innovative practices at 4S WRF over the past several years include the installation of monitoring equipment that makes immediate adjustments in the treatment process, which stood out to the CWEA judges. The equipment not only keeps the facility in regulatory compliance but also reduces treatment costs for ratepayers. In addition, to obtain higher water quality and reduce energy costs, OMWD installed a more efficient ultraviolet disinfection system.

OMWD meets up to 15 percent of its overall demand with recycled water. 4S WRF can transform up to two million gallons of wastewater to recycled water each day. This alternative water supply reduces the use of drinking water for the irrigation of golf courses, parks, schools, streetscapes, and homeowner association common areas.

Recycled Water Pipeline Projects Ensure Reliable Water Supplies for Olivenhain Municipal Water District

/in , /by

Olivenhain Municipal Water District is beginning construction on new recycled water pipelines in Encinitas. The pipelines are part of a larger expansion of OMWD’s recycled water distribution system that will result in the savings of more than 12.5 million gallons of imported drinking water each year.

This phase of the project involves installing pipelines on Summerhill Drive and Village Center Drive in Encinitas. Work is scheduled to take place Monday through Friday, 8:30 a.m. to 3:30 p.m. Additionally, restricted work hours of 9 a.m. to 2 p.m., Monday through Thursday, and 9 a.m. to noon on Friday, will be in effect for any work directly impacting Diegueño Middle School.

Other project phases involved the construction of recycled water pipelines around Park Dale Lane and Gatepost Road in Encinitas, which are now complete, and along Calle Barcelona in Carlsbad, on which work continues. This project is anticipated to be completed in spring 2025. No impacts to customers’ drinking water supplies are anticipated.

Minimizing Traffic Disruptions for Customers

OMWD is coordinating with the cities of Carlsbad and Encinitas on a traffic management plan to minimize traffic disruptions for residents and businesses during construction. Learn more in the video presentation below.

OMWD successfully secured approximately $900,000 in grant funding to make this project cost-effective for ratepayers. Specifically, both the US Bureau of Reclamation and the California Department of Water Resources are contributing grant funds to offset project costs.

Ensuring Safe, Reliable Water Supplies

OMWD receives 100 percent of its drinking water supply from the Sacramento-San Joaquin Delta and the Colorado River. These sources have become unreliable due to droughts and overuse.

Recycled water is locally produced, disinfected wastewater used for irrigation. It is a drought-resilient supply and costs less than potable water. In addition, using recycled water reduces the amount of treated wastewater discharged to the ocean and reduces our dependence on imported water from faraway sources.

OMWD has identified opportunities in Encinitas and Carlsbad to connect more customers to its recycled water distribution system. The completion of the pipeline extensions will result in the conversion of 28 water meters from potable to recycled water, saving more than 12.5 million gallons of imported drinking water every year.

OMWD produces up to two million gallons of recycled water daily at its 4S Ranch Water Reclamation Facility. Additionally, OMWD 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 expand the reach of the recycled water.

As a result, OMWD now serves up to 15 percent of its overall demand from recycled water and continues to identify additional ways to make recycled water available to eligible customers.

4S Ranch Water Reclamation Facility-CWEA 2022 Plant of the Year

Olivenhain Municipal Water District Marks Milestone Recycled Water Anniversary

/in , /by

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.
