Expansion Project Doubles Treated Water Deliveries to Otay Water District
December 08, 2009

The San Diego County Water Authority completed construction of its Otay 14 Flow Control expansion project, preparing it for connection to a new 36-inch Otay Water District pipeline. When complete in summer 2010, the pipeline will double daily treated water deliveries to the Otay Water District to 16 million gallons per day. The flow control expansion project is a key component of the Water Authority’s East County Regional Treated Water Improvement Program (ECRTWIP).

 “By making full use of treated water produced locally, the program helps reduce the demand and need to import drinking water from other distant water treatment plants, such as the R.F. Skinner Water Treatment Plant located in southern Riverside County and the Water Authority’s Twin Oaks Valley Water Treatment Plant,” said Water Authority Board Chair Claude A. “Bud” Lewis. “The expansion of the Otay 14 Flow Control Facility is an important part of our efforts to increase water supply reliability.”

The Water Authority, Lakeside Water District, Padre Dam Municipal Water District, Otay Water District and Helix Water District implemented the ECRTWIP in 2006 to increase the amount of treated water available from the Levy Treatment Plant and reduce demand on the Water Authority’s regional aqueduct delivery system.

Various flow control facilities, pump stations and pipelines will also be upgraded as part of the ECRTWIP.

The Otay 14 Facility is located on the corner of Third Street and Lexington Ave. in El Cajon, has been in service six years. It draws treated water from the Helix Water District’s R. M. Levy Water Treatment Plant, which produces up to 106 million gallon of drinking water per day, enough to accommodate annual needs of 650 average households of four people.
