Aurora, Illinois Storm Drain Discharge Rules

Utilities and Infrastructure Illinois 4 Minutes Read · published February 10, 2026 Flag of Illinois

Aurora, Illinois residents must prevent pollutants from entering the municipal storm drain system. Illicit discharges—any flow into storm drains that is not solely stormwater—threaten local waterways, public health, and the citys MS4 permit obligations. This guide explains how Aurora defines and enforces illicit storm drain discharges, how residents should report suspected discharges, and what steps to take to comply with local rules. For official program details and reporting tools see the Citys stormwater program and municipal code references below.[1][2]

What is an illicit storm drain discharge?

An illicit discharge is any direct or indirect non-stormwater discharge to the storm drain system, including but not limited to chemical wastes, motor oil, paint washout, sewage, or other liquids that may harm water quality. Routine, lawful stormwater and authorized discharges (for example permitted construction dewatering when approved) are excluded where a permit or variance applies.

Report visible sheens, colored flows, or strong odors immediately to help protect local creeks.

Penalties & Enforcement

Aurora enforces illicit discharge rules through municipal ordinances and its Public Works / Stormwater division. Specific monetary fines, escalation patterns, and administrative remedies depend on the controlling code sections and departmental rules.

  • Escalation: first, repeat, or continuing offence ranges are not specified on the cited page and may be set by ordinance or administrative order.[2]
  • Non-monetary sanctions: the city may issue orders to cease discharge, require cleanup or remediation, suspend approvals, or pursue civil enforcement; exact remedies are set by code or departmental procedures.[2]

If you see an active hazardous discharge, prioritize safety and notify emergency services and the city immediately.

Applications & Forms

The city does not publish a specific "illicit discharge" permit form on the cited pages; required permits (for allowed dewatering or construction discharges) are referenced through public works/stormwater program materials or the municipal code.

Action steps for residents
