Stormwater Management

Overview

Under the terms of the Connecticut Department of Energy and Environmental Protection (DEEP) General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4) effective July 1, 2017, the City of Danbury is required to implement and enforce a stormwater management program to reduce the discharge of pollutants (including but not limited to motor oils, gasoline, fertilizers, pesticides, bacteria from pet waste and other sources, and sediment from construction sites) from runoff entering and passing through the municipal storm sewer system and to protect the water quality of the various lakes, ponds, streams, rivers and other water bodies within the limits of the City. Urban stormwater runoff is the leading cause of water quality impacts to surface water in the city, state, and nation. This webpage provides copies of the City's permit and Stormwater Management Plan as well as sources of information available to promote citizen involvement in and knowledge of means and methods to reduce pollutants in stormwater runoff.
