In Houston, Texas, illicit stormwater discharges—including sewage, industrial spills, or contaminated runoff—threaten waterways and public health. This guide explains how residents and businesses can report suspected illegal discharges, what the City’s stormwater program and enforcement options are, and the practical steps to get an immediate response or follow up. Use the official complaint channels below to ensure the City logs, investigates, and documents the incident.

How to report an illicit discharge

When you observe an active spill, colored or odorous runoff, illegal dumping into a storm inlet, or a visible pipe discharging to a creek, report it promptly. For non-emergencies use the City of Houston 311 online portal or phone service to file a report. Call or submit via 311[1]. For stormwater program information and guidance on what to report, consult Houston Public Works Stormwater pages. Houston Public Works - Stormwater[2].

  • Call 311 or use the 311 portal; provide location, description, photos, and time of observation.
  • Note landmarks and take photos or video if safe; record any visible pipe numbers or business names.
  • Keep your 311 case number for follow-up and to request status updates.
  • For chemical or hazardous material releases, report to emergency responders and request HazMat response via 911 when there is immediate danger.
Report quickly and include photos to speed investigation.

Penalties & Enforcement

The City of Houston enforces stormwater and illicit discharge controls through its stormwater program and municipal code provisions. Specific monetary fines and penalty schedules are governed by the City code and related enforcement policies; exact fine amounts are not specified on the cited pages below and may be set by ordinance or administrative rule. See Houston Code of Ordinances[3].

  • Fine amounts: not specified on the cited page; check the City code or contact Public Works for current schedules.
  • Escalation: the cited sources do not list first/repeat offender ranges; enforcement may escalate from warnings to civil penalties or abatement orders.
  • Non-monetary sanctions: may include stop-work or corrective orders, mandatory cleanup, equipment seizure, injunctive relief, or referral to municipal or civil courts.
  • Enforcer and inspection: Houston Public Works (Stormwater) is the primary department for stormwater quality enforcement; complaints filed through 311 trigger inspection and investigation by City staff. Houston Public Works - Stormwater[2].
  • Appeals and review: the cited pages do not specify appeal time limits or procedures; contact the enforcing office listed on the enforcement notice or 311 for appeal instructions.
Official notices will list appeal steps and deadlines—act quickly on any notice.

Applications & Forms

The City’s stormwater pages explain reporting and program contacts; there is no single city form published on those pages specifically labeled as an "illicit discharge" application. For construction or industrial site requirements, consult permit and plan submittal guidance on the Public Works pages or linked permitting sites. Houston Public Works - Stormwater[2]. If a specific enforcement or permit form is required, the enforcement notice or the City webpage will identify the exact application and submission method.

Most reports are handled via 311 rather than a separate printable form.

Common violations and typical outcomes

  • Unauthorized discharge from industrial sites or dumpsters leading to cleanup orders and possible fines.
  • Discharge of sewage or sanitary waste into storm drains resulting in immediate investigation and abatement directives.
  • Failure to maintain construction site controls (silt fences, basins) causing sediment discharge and enforcement actions.

Action steps

  • Call 311 immediately for non-life-threatening spills and provide detailed location and evidence.
  • Preserve photos and timestamps; save the 311 case number and request follow-up.
  • If you receive an enforcement notice, follow the corrective actions and ask the issuing official about appeal deadlines.
