The San Diego Regional Water Quality Control Board (San Diego Water Board) is cracking down on water wasters throughout its region to stem pollution that is generated by overwatering.

With the state in a fourth year of extreme drought conditions, the San Diego Water Board recently initiated compliance audits to determine which cities are taking effective measures to eliminate over-irrigation – a requirement of storm water regulations adopted more than five years ago.

These efforts are put in place to ensure that water quality isn’t degraded by runoff containing bacteria and fertilizers that are transported in local streams and eventually to the ocean.

This isn’t just about water conservation, it’s about runoff that affects public health and impacts ecosystems.  Landscape over-irrigation is a serious threat to water quality. It runs through the gutters and storm drains to the nearest creeks, lagoons, and beaches with fecal pathogens from pet waste that make people sick, excess nutrients from fertilizers that cause nuisance algae blooms, and lawn and garden pesticides that kill fish and shellfish.

While the San Diego Water Board’s over-irrigation discharge prohibition preceded Governor Edmund G. Brown Jr.’s January 2014 emergency drought proclamation, the prohibition compliments the State’s new emergency conservation regulation.  Conserving water prevents water pollution from occurring in the first place.

The San Diego Water Board’s mission is to preserve, enhance and restore California’s water resources and ensure their proper allocation and efficient use for the benefit of present and future generations.
