Stormwater Quality & Pollution Prevention
When it rains in Wildomar, rainwater runs off rooftops, parking lots, driveways, lawns, cars, streets, and open land. Depending on its location in the City, this rainwater runoff (or stormwater runoff) drains to Lake Elsinore or to the Murrieta Creek, either by surface flows or through a storm drain system. The Murrieta Creek drains to the Santa Margarita River which ultimately drains to the Pacific Ocean. Stormwater runoff carries with it all the pollutants it encounters. This runoff does not go to a sanitary sewer system or a treatment plant but is discharged directly to a waterbody without any treatment. In addition, water runoff that is not attributed to rain (also known as non-stormwater runoff) such as irrigation runoff, car washing runoff, or power washing runoff, also carries pollutants to downstream waterbodies. These pollutants can affect the quality of water in the waterbodies and limit beneficial uses of the waterbodies (such as swimming, fishing, drinking water, etc…). A visual representation of how stormwater runoff drains is provided on this page.
To address these sources of pollution in stormwater and non-stormwater runoff, the City of Wildomar implements a stormwater pollution program, referred to as a National Pollutant Discharge Elimination System (NPDES) Program. This page includes information regarding the City’s NPDES Program and how it applies to members of the Wildomar community.

The City's NPDES Program is mandated and regulated by the California Regional Water Quality Control Board, San Diego Region (Regional Board), per their Order Number R9-2013-0001, as amended by R9-2015-0001 and R9-2015-0100 issued by (NPDES Permit). The City enforces the requirements of the NPDES Program through it's "Stormwater Drainage System Protection" Ordinance (Chapter 13.12 of the Wildomar Municipal Code).
