The Olivenhain Municipal Water District’s 4S Ranch Water Reclamation Facility was named 2022 Plant of the Year by the California Water Environment Association.

At its March 15 meeting, the Olivenhain Municipal Water District Board of Directors accepted the award as the CWEA San Diego section’s 2022 Plant of the Year. The Plant of the Year award acknowledges OMWD’s 4S Ranch WRF accomplishments in regulatory compliance, innovative practices, cost-effectiveness, and superior plant operations.

Expanding the use of recycled water

“OMWD is dedicated to providing recycled water and wastewater treatment in a fiscally responsible and environmentally responsive method,” said Board Vice President Matthew Hahn. “Our board is proud to have our recycled water facility recognized at the state level as a first-class treatment plant that meets or exceeds all regulatory standards and demonstrates industry best management practices.”

OMWD has spent the last several years expanding the use of recycled water within its service area and raising public awareness of the importance of treating wastewater to be reused for non-potable uses like landscape irrigation. The 4S Ranch Water Reclamation Facility can produce up to two million gallons of high-quality recycled water each day, reducing the use of drinking water for the irrigation of golf courses, parks, schools, streetscapes, and homeowner association common areas.

Proactive maintenance saves customers money

CWEA’s award program recognizes proactive maintenance as a priority, as it helps to avoid costly emergency repairs and ensures continued wastewater and recycled water services for customers. 4S WRF operators maintain over 85 miles of sewer collection system pipelines, lift stations, a 410-acre-foot storage pond, and a one-million-gallon reservoir to provide wastewater and recycled water services.

Founded in 1927, the California Water Environment Association is a not-for-profit association of 9,000-plus professionals in the wastewater industry. The association trains and certifies wastewater professionals, disseminates technical information, and promotes sound policies to benefit society through protection and enhancement of our water environment.

Olivenhain Municipal Water District is a public agency providing water, wastewater services, recycled water, hydroelectricity, and operation of Elfin Forest Recreational Reserve. Organized in 1959, OMWD currently serves approximately 87,000 customers over 48 square miles in northern San Diego County.
