About Bonita
Bonita lies in the South Bay next to Chula Vista, about 9 miles from downtown San Diego in a straight line, and had 12,917 residents at the 2020 Census. Bonita Road, San Miguel Road and Sweetwater Road are the main routes, Bonita Highlands sits on the hills, and Bonita Golf Course and Sweetwater Reservoir are local landmarks. The median home dates to about 1975, so many houses carry original water heaters, supply lines and drain piping from that era, and repiping or drain replacement is a common conversation.
Sweetwater Authority water
Sweetwater Authority serves Bonita along with National City and the western and central parts of Chula Vista. Its report describes a blend of Sweetwater River water stored in Sweetwater Reservoir, deep freshwater wells in National City, brackish groundwater from Chula Vista wells treated by reverse osmosis, and imported Colorado River or State Water Project water. Surface water is treated at the Robert A. Perdue Water Treatment Plant, and chloramine is used as a disinfectant. Sweetwater's report lists total hardness from about 94 to 300 ppm, averaging around 196 ppm, which is enough to leave scale in water heaters and on faucets and to make a softener worth considering.
Sweetwater's lead service line inventory found no lead or galvanized service lines needing replacement, customer-owned lines included. That covers the service lines, not plumbing inside the house. Customer service and after-hours water emergencies both go to (619) 420-1413.
Backflow testing
Sweetwater Authority runs its own Cross Connection Control and Backflow Prevention program. Devices are required for, among others, homes with auxiliary water sources, pumps or fire sprinkler systems, multi-unit complexes, wells and gray water systems. Each device must be tested when installed and every year afterward by a tester the Authority has certified and approved, and the customer pays for installation, testing, maintenance and repair.
Gas safety
SDG&E provides natural gas in San Diego County. When you smell gas, the first step is to leave. After that, call 911 and SDG&E at 1-800-611-7343 from a safe place.
Sewer and permits: check your address
Bonita's sewer provider and permit office were not confirmed in our research, so check the sewer agency on your property tax or utility bills, and before permitted work, confirm with the building department that covers your address which office issues the permit.
Bonita versus the City of San Diego
A San Diego address gets city water and the city's backflow tester list. Bonita uses Sweetwater Authority for water and backflow rules and a different permit office. Call the number on this page, explain the problem, and you will be connected with an independent plumber who works in Bonita and agrees on price and timing with you.
