Water Quality

the water cycleEvery year, the U.S. Environmental Protection Agency and the State Water Resources Control Board, Division of Drinking Water set regulations that limit the amount of contaminants that may be present in drinking water provided by the District.

Once again, the Otay Water District is proud to have met all state and federal water quality standards for calendar year 2017. The District’s annual Consumer Confidence Report provides details on the results and other valuable information about the water supplied by the District. Customers can learn more about where their water comes from, what it is tested for, and how the results compare to state standards. The report also lists the levels of common elements that may be detected in the water.

Otay provides a safe and reliable water supply to nearly 224,000 customers in the communities of Otay Mesa, Chula Vista, Jamul, Spring Valley, Rancho San Diego, and unincorporated areas of El Cajon and La Mesa. To ensure that the quality of your tap water meets standards, Otay and the agencies it purchases its water from continually test water sources at the treatment plants and at points in the distribution system.

The water sources delivered by Otay include the Colorado River, the State Water Project, and local supplies including seawater desalination from the Carlsbad Desalination Plant. Otay purchases its treated water from the San Diego County Water Authority, Helix Water District, and Metropolitan Water District of Southern California.

Otay vigilantly safeguards its water supplies. Using one or more state-certified laboratories, Otay routinely analyzes its supply for an entire range of elements that have the potential to degrade the quality of drinking water.
