Stormwater Management

2019 Annual Report - General Permit for the Discharge of Stormwater

What is Stormwater Management? 

When rain events take place, water inevitably flows through those unprotected, eroded soil surfaces and have the potential to transport sediment into U.S. waterways. This sediment-laden water is referred to as, “stormwater.” As that “stormwater” flows over construction and industrial sites, it can  carry other pollutants ranging from pesticides, chemicals and asphalt, to petroleum, and other debris collected from the soil surface and deposit those materials into water sources that serve as drinking water, aquatic habitats, and even public beaches and swimming areas. Urban stormwater discharged from storm sewers, often referred to as “Municipal Separate Storm Sewer Systems” (MS4s), has been found to be a leading source of water quality impairment. The stormwater flow picks up and transports these pollutants and then discharges contaminated water into U.S. waterways through MS4s. A copy of Haddam's 2017 Stormwater Management Plan here

There are many resources to educate us on the MS4 program.
