Stormwater Management

Why does Stormwater Quality Matter?

Stormwater runoff, created from rain and snow melt, is a leading cause of water pollution.

As stormwater runoff drains across streets, parking lots and lawns, it carries with it pollutants such as automotive leaks, excess fertilizer, pet waste and sediment.

Unlike the sanitary sewer system that conveys waste through pipes from buildings for treatment at a wastewater treatment facility, stormwater is conveyed through the storm sewer system—comprised of streets, pipes, and channels — directly to waterways. Instead of treatment at a wastewater facility, stormwater runoff is treated by filtration through vegetation, or by infiltration into the ground.  However, the BEST method to treat stormwater is to prevent the source of pollution in the first place.

Golden Stormwater Quality Program

The primary function of the city’s Stormwater Quality Program is to minimize pollutants transported by stormwater runoff into the storm sewer system and subsequent receiving waters. The Stormwater Program is regulated by the Clean Water Act under the National Pollutant Discharge Elimination System (NPDES) and is administered by the Colorado Department of Public Health and Environment.  Golden’s program:

  • Provides education about how to prevent pollutants in stormwater runoff that impact water quality.
  • Administers permits and monitors construction sites for pollutants during construction.
  • Assists with investigation of spills and illegal dumping into the storm sewer system.
  • Administers municipal stormwater program in accordance with the Colorado Discharge Permit System Stormwater regulations.  A Program Description Document is available to the public for review and comment.

Spills and Illegal Dumping

It is illegal to discharge anything other than stormwater (rain and snowmelt) into the storm drainage system (streets, gutters, inlets, drainage ways). Some exceptions may apply.  For a complete list see Municipal Code 13.30.140.   Call the Police Department at (303) 980-7300 to report illegal dumping activity.
