Wildomar gets both water and sewer from Elsinore Valley Municipal Water District (EVMWD), whose backflow rules call for testing at installation and every year after by a County of Riverside certified tester. Building permits come from the City of Wildomar. Plumber Oceanside is a free referral service, not a plumber; call the number on this page to be connected with a local plumber in Wildomar.

Plumbing services in Wildomar
A young city on I-15
Wildomar lies in southwestern Riverside County along Interstate 15, between Lake Elsinore and Murrieta, and its center is about 27 miles from central Oceanside in a straight line. It incorporated on July 1, 2008, and the 2020 Census counted 36,875 residents. Clinton Keith Road, Bundy Canyon Road and Mission Trail are main routes, Sedco Hills is one of its neighborhoods, and the Iodine Springs Reserve and Inland Valley Medical Center are local landmarks. The surrounding hills are covered in coastal sage scrub and chaparral, and the town has roots in railroads and honey production.
One district for the tap and the drain
The City of Wildomar names Elsinore Valley Municipal Water District as its water and sewer provider, including wastewater treatment and disposal. EVMWD's main number is (951) 674-3146, and it publishes an annual water quality report where customers can look up hardness and treatment details. EVMWD states that once water passes through the meter, keeping it free of contamination is the customer's responsibility, which is one reason the district takes backflow seriously.
Backflow testing rules
EVMWD runs a state-required Cross-Connection Control Program. New commercial, industrial and landscape services need a backflow device right after the meter, and agricultural services often do too. Devices belong to the property owner, must be tested when installed and every year after, and may only be tested by someone certified by the County of Riverside Department of Environmental Health. A device that fails has to be repaired and retested within 15 days. The district's Water Protection Department answers at (951) 625-3404.
Housing and climate
The median Wildomar home was built in 1994, so most plumbing is relatively modern, and the work tends toward water heaters, fixtures, pressure issues, irrigation lines and slab leaks. Summers in the inland valley are hot and dry, and cold winter nights can bring frost to exposed pipes and backflow assemblies, so insulating outdoor piping is worth doing.
Permits and gas
Building permits are submitted through the City of Wildomar's online permit portal. City Hall is at 23873 Clinton Keith Road, Suite 110, and the main number is 951-677-7751. The city names SoCalGas as its natural gas provider. If you smell gas, leave the area right away, then call 911 and SoCalGas at 1-800-427-2200 from a safe distance.
What's different from Oceanside, and calling
Oceanside's water and sewer come from the City and its gas from SDG&E. Wildomar relies on a regional water district for both services, SoCalGas for gas and county-certified testers for backflow. Call the number on this page, describe the problem, and you will be connected with an independent plumber serving Wildomar who agrees on cost and scheduling with you.
