Summary
Danbury bans discharging anything but stormwater into its storm drain system and requires best-management practices to keep pollutants out, enforced by the Public Works Director under Chapter 49.
General prohibition. No person shall intentionally, negligently or irresponsibly throw, drain, or otherwise discharge or cause to be discharged, or allow others under its control to throw, drain, or otherwise discharge into the MS4 or into the waters of the state any materials, including, but not limited to, pollutants or waters containing any pollutants, other than stormwater.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 2).
Full Breakdown
Chapter 49, the Illicit Discharge and Connection Ordinance, prohibits dumping or draining any non-stormwater material into Danbury's municipal separate storm sewer system (MS4) or the waters of the state. Construction and industrial operators must submit their CTDEEP stormwater permit registration to the Director, and any property that may pollute stormwater must adopt structural or non-structural BMPs. The Director inspects, can suspend MS4 access, and records violations on the Danbury Land Records until corrected.
Violations & Fines
Civil penalty up to $250 per day per violation after a notice-of-violation deadline passes; MS4 access can be suspended; appeals go to a citation hearing officer within 7 days.
