Utilities and Infrastructure Texas 3 Minutes Read ยท published February 07, 2026 Flag of Texas

El Paso, Texas maintains rules to prevent pollutants from entering the storm drain system. This guide explains what constitutes an illicit discharge, how the city enforces the rules, how to report suspected discharges or spills, and practical steps residents and businesses should take to comply.

Illicit Discharges and the Storm Drain System

An illicit discharge is any discharge to the storm drain system that is not composed entirely of stormwater, including sanitary wastewater, motor oil, paint, solvents, concrete washout, and other pollutants. These discharges travel untreated to local arroyos and the Rio Grande, harming water quality and public health.

Report visible sheens, colored runoff, or strong chemical odors immediately to city stormwater authorities.

Common Sources and Examples

  • Construction dewatering or concrete washout discharged to curb inlets.
  • Illicit connections from building drains to the storm drain system.
  • Deliberate dumping of motor oil, antifreeze, or household chemicals.
  • Accidental spills from vehicle crashes or industrial operations.

Where specific monetary penalties or structured escalation are not shown on the official stormwater pages, the provisions are listed as "not specified on the cited page" below and official contacts are provided in Resources.
