What is an illicit storm drain discharge?

An illicit discharge is any non-stormwater flow or pollutant entering a storm drain system, including paint, motor oil, sewage, industrial wash water, or intentional dumping.

How to report an illicit storm drain

Collect safe, objective details: location, time, visible pollutant type or color, flow path to the storm drain, photos or video, and vehicle or property descriptions if applicable. Then submit a report to the county public works hotline or online report form; do not enter contaminated water. For county reporting options and submission details see the local public works reporting page [1]. For state-level complaints and stormwater rules reference the California State Water Resources Control Board program pages [2].

  • Note the date and time of observation and any ongoing flow.
  • Photograph the discharge, the storm drain inlet, nearby addresses, and any identifying vehicle or container.
  • Call the county report line or use the online form to submit basic information and attach photos.
  • If there is an immediate hazard to people or a large spill, call emergency services (911) first.
Do not attempt to clean or enter polluted stormwater; evidence and safety are the first priorities.

Investigation process and typical violations
