Municipal Storm Sewer Systems (MS4s)

Municipal Separate Storm Sewer Stormwater (MS4) 

Stormwaters, such as rain and snow melt, which run over impervious surfaces in urbanized areas – roadways, sidewalks, parking lots, roof tops, etc. – are often unintentionally, or unknowingly, mixed with potential sources of pollutants. Waters travel quickly over these impervious areas and can carry large quantities of materials.

Stormwater - Construction Activities

Stormwater runoff from construction activities can have a significant impact on water quality and increase the rates at which runoff leaves a project site. As stormwater flows over a construction site, it can pick up pollutants like sediment, debris, and chemicals and transport these to a nearby storm sewer system or directly to a river, lake, or coastal waterways.

Stormwater Pollution

What is Stormwater?

When it rains it drains logoStormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground.

The Clean Water Act

The Clean Water Act (CWA) is the cornerstone of surface water quality protection in the United States. The statute employs a variety of regulatory and nonregulatory tools to sharply reduce direct pollutant discharges into waterways, finance municipal wastewater treatment facilities, and manage polluted runoff.
