Celebrating 65 Years as Your Water Service Provider

In 2021, the Otay Water District is proud to celebrate its 65th year of providing communities of southeastern San Diego County with reliable water service.


On an overcast summer day in 1955, a plumber, a civil engineer, an attorney, a newspaper publisher, and two owners of large tracts of land gathered for lunch at Christie’s Restaurant in Chula Vista. They met to discuss how they could bring life-giving water to an arid region of southeastern San Diego County. By the end of the day, they had a common vision, a few thousand dollars to spend, and the framework for what later became the Otay Water District.

In 1956, water was finally brought to the arid region that was mostly a scrub- and cactus-covered backcountry with a population of less than 1,200.


Today, the District provides reliable water, recycled water, and sewer services to more than 226,000 people. Its service area includes parts of eastern Chula Vista, Bonita, Jamul, Spring Valley, Rancho San Diego, east Otay Mesa, and unincorporated areas of El Cajon and La Mesa. These communities are provided with imported water from the Metropolitan Water District of Southern California, the San Diego County Water Authority, and the Helix Water District.

Throughout the 65 years, the District hit various milestones to continue serving the growing population in its service area.

One major highlight in Otay’s history includes the construction of its Ralph W. Chapman Water Recycling Facility in 1979. The plant is used to irrigate a portion of eastern Chula Vista and can produce up to 1.1 million gallons of recycled water per day. The District is committed to increasing the use of recycled water in its service area to minimize the overall demand for potable water.

To assure efficient operations, comply with regulations, and replace aging infrastructure, the District regularly invests in capital improvement projects. One important undertaking includes the Ralph W. Chapman Water Recycling Facility 14-Inch Force Main Improvement Project located in the San Diego National Wildlife Refuge and completed in 2017. After the pipeline’s 37 years of service and a recent leak, the District used advanced technologies and sophisticated analysis software to discover that it was still in excellent condition. With proactive maintenance and repair measures, the District preserved the remaining useful life of the existing three-mile-long pipeline facility.

Also in 2017, the District began taking advantage of manufacturer warranties to upgrade more than 49,600 automated meter reading (AMR) registers, which were originally installed between 2004 – 2012. Replacing registers instead of the entire meters as well as taking advantage of existing warranties helped save ratepayers approximately $3.3 million in meter replacement costs. Benefits of utilizing AMR meters include reduction of full-time meter reading staff, increase in the safety of staff, allowing staff to store historical water-use data, and identifying unexplained usage by providing leak, tamper, and back-flow detection alarms.

In 2018, after a two-year study and evaluation period, Otay began using drones to assist with the preliminary inspection of water facilities, including 40 potable water reservoirs. Drone technology can provide time savings with initial inspections and allows for a safer examination process of the District’s assets.

These specific milestones have also been instrumental in helping our service area do its part in reducing water waste and overall water use — which is especially important during drought. In recent years, San Diego County has been better prepared for drought than other parts of California. This is partially due to the District’s heavy investment in water conservation, water recycling, seawater desalination, and transitional storage over the last 20-plus years.

Although it may look different today, the District remains as dedicated to community service as in its early roots. Responsible resource planning, sound fiscal management, respect for the environment, and paying close attention to its customers’ needs are necessary to ensure its future looks as good as its history.
