What is an illicit storm drain discharge

An illicit discharge is any non-stormwater liquid or waste entering the municipal storm drain system, including motor oil, paint, concrete wash, detergents, sewage, or industrial process water. If you see colored or odorous flow, visible sheen, or solids entering a storm grate or roadside ditch, treat it as a reportable incident.

Report suspect flows immediately to reduce environmental damage.

How to report

  • Call the City of Bellevue Storm and Surface Water Utility reporting line or use the online reporting form for illicit discharges and spills. Report an illicit discharge[1]
  • Document the location, time, photos or video, direction of flow, and any visible pollutants.
  • If safe, try to contain the source (e.g., block off area, divert runoff) but do not attempt hazardous cleanup without proper training.
Prompt reporting improves cleanup outcomes and legal response options.
