Report Stormwater Pollution

Nothing besides rain water is allowed to be dumped into a storm drain. This includes: wash-waters, sewage, automotive fluids, construction materials, paint, sediment and/or silt, and food wastes. Reporting incidents of water pollution problems such as illegal dumping or discharges help keep our local creeks, San Francisco Bay, and the Pacific Ocean clean.

When to make a report?


  • When you notice unusual odors in or near the storm drain
  • When you find dumped waste in or near the storm drain
  • When the drainage system has unusually large flows during dry periods
  • When you see someone illegally dumping anything into the storm drain
