El Cajon Stormwater and Sewer Connection Rules

Environmental Protection California 3 Minutes Read ยท published March 01, 2026 Flag of California

In El Cajon, California, stormwater and sewer connection rules set requirements for preventing pollution, obtaining permits, and making safe sewer lateral connections. Property owners and contractors must follow city design standards, obtain required permits for new or modified connections, and prevent illicit discharges to the storm drain system. The city enforces standards through the Public Works and Development Services departments and provides guidance and reporting tools for spills, construction runoff, and illegal connections. Early consultation with Development Services helps avoid costly rework and enforcement actions; for local program details see the City Stormwater Program Stormwater Program[1].

Report illegal discharges promptly to reduce environmental harm.
