In San Francisco, California, illicit discharges to storm drains can harm water quality, public health, and the Bay. This guide explains how to identify and report illegal storm drain discharges, who enforces the rules, likely penalties, and the exact steps to submit a complaint to city agencies. Use the official reporting channels to ensure timely response and documentation. If the situation is an active spill or immediate danger, follow emergency reporting instructions below.

How to report an illicit discharge

When you see suspicious flows, oily sheens, sewage, colored liquids, or solids entering a gutter, street inlet, or storm drain, document the location, time, photographs, and direction of flow. Report via the official city reporting pages and hotlines listed below so the responsible department can investigate and contain the discharge.

  • Call the city pollution/works hotline or 311 for non-emergencies.
  • Take photos and note nearby addresses, business names, or vehicle descriptions.
  • Record the date and time of discovery and any observable sources.
Report early to reduce downstream harm and evidence loss.

Use the official reporting pages to submit details and attach photos so investigators can prioritize field response. The San Francisco Public Utilities Commission, Department of Public Works, and San Francisco Environment programs coordinate responses and enforcement depending on the source and nature of the discharge.SFPUC water quality pages[1] SF Environment stormwater information[2] San Francisco Public Works reporting[3]
