Manchester, Connecticut

Storm Water Pollution Prevention

In 2004, the Town of Manchester developed a townwide Stormwater Management Plan. This plan is a required component of the Connecticut Department of Environmental Protection (DEP) General Permit for the Discharge of Stormwater for Small Municipal Storm Sewer Systems , more commonly known as the "MS4" permit. The goal of the MS4 permit program is to improve overall water quality by reducing the amount and potential for pollutants to enter our water system. The Stormwater Management Plan identifies measurable goals in each of the following six control measures: Public Education and Outreach; Public Participation and Involvement; Illicit Discharge Detection and Elimination; Construction Site Runoff Control; Post-Construction Runoff Control; and Pollution Prevention/Good Housekeeping. The overall purpose of the program is to protect the quality of our natural resources by reducing the discharge of pollutants to wetlands and watercourses.

DEP requires that towns annually submit reports documenting their progress towards achieving the goals for each control measure that were originally identified in the 2004 Stormwater Management Plan. They also require that towns sample and test stormwater runoff from predetermined representative locations and submit the results to DEP.

The Town has made considerable progress towards the goals originally identified in the 2004 Plan, as documented below in the annual reports submitted to DEP:

The MS4 permit mentioned above contain Best Management Practices (or BMP's) for the Town's operations.Reducing the amount of pollutants entering our watercourses is important because it affects plants, fish, animals and people. After it rains, stormwater runoff can pick up chemicals, debris, sediment and other pollutants from the ground as it flows untreated into the water bodies we use for recreation purposes and sources of our drinking water. Everyone can play a part in reducing these pollutants from entering our water bodies. Below are some brochures and links that show ways you can help.
