The City of Temecula is committed to improving water quality by implementing programs that systematically reduce and eliminate pollutants from urban runoff before reaching our local creeks.

To effectively address this issue, the City adopted EPA's National Pollution Discharge Elimination System (NPDES) regulations as part of the City's Water Quality Program and Sustainability Program to reduce pollutants in urban runoff and in storm water.
As part of the NPDES regulations, the City of Temecula was issued a Municipal Separate Storm Sewer System (MS4) Permit by the San Diego Regional Water Quality Control Board. This State Permit places pollution prevention requirements on planned developments, construction sites, commercial and industrial businesses, municipal facilities and activities, and residential communities.
