Stormwater Program

Post

Central San works with the Contra Costa Clean Water Program (CWP) to perform storm water inspections in the ten incorporated cities of central Contra Costa County. The cities have authorized Environmental Compliance staff to conduct inspections of commercial/industrial businesses and to enforce storm water management ordinances to prevent storm water pollution. Central San inspectors combine these inspections with the sanitary sewer compliance inspections whenever possible to reduce the number of inspection visits required for a business. Central San considers the combined inspection programs to be efficient because improper discharges to the storm water collection system can, in some cases, be corrected by redirecting the process discharge to the sanitary sewer system.
