What is an illicit stormwater discharge

An illicit discharge is any non-stormwater flow into the municipal storm sewer system or waterways, including sewage, industrial waste, yard waste, or improperly managed construction runoff. Common signs include unusual color, sheen, strong odors, visible solids, or consistent flow during dry weather.

How to document and report

Gather clear details before filing: date/time, precise location, photos or video, description of the pollutant, and any vehicle or business identifiers. If the discharge poses an immediate public-health or safety risk, call emergency services first.

  • Take dated photos or video showing the discharge source and affected water.
  • Note the time and weather conditions when you observed the flow.
  • Record any identifying marks like business names, vehicle plates, or visible equipment.
Good photos and exact location speed city response and enforcement.
