This guide explains how to identify illegal dumping into storm drains, who enforces city rules in Phoenix, how to report incidents, and what to expect after a complaint is filed.

What counts as illegal dumping into storm drains

Illegal dumping includes liquids, solids, paint, motor oil, chemicals, construction debris, yard waste, and other materials placed in streets, gutters, curb inlets, or storm drain openings that can enter the storm drainage system. If the material can be carried by runoff into natural streams or waterways, it is typically considered an illicit discharge under Phoenix stormwater rules.

How to identify and document an incident

  • Note the exact location (nearest address or intersection) and the direction of flow.
  • Take clear photos or short video showing the substance, the drain inlet, and any identifying marks on containers or vehicles.
  • Record the date and time, and if possible, take a license plate number or description of persons involved.
Do not attempt to clean hazardous spills yourself; keep a safe distance and notify authorities.

Reporting process

To file a report with the City of Phoenix, use the official stormwater/reporting channel maintained by the City of Phoenix Stormwater Program via the city website City of Phoenix Stormwater Program[1]. Provide photos, location, time, and any suspect vehicle or person information. If the incident poses immediate danger or involves hazardous materials, call 911 or the appropriate emergency response number first.
