Stormwater Management

Have you ever wondered where all the water goes when it rains or after the snow melts?  Some of it seeps into the ground or evaporates, but much of it runs off over the land, down streets and into a storm drainage system. This runoff water is called stormwater

The Framingham Public Works Department manages the Town’s Municipal Separate Storm Sewer System (MS4).  This system, also known as the drainage system, includes about 65 miles of drainage pipe connecting 8,000 catch basins (also called drains) and 2,000 drainage manholes. 

The Town is authorized to discharge stormwater through the Phase II National Pollutant Discharge Elimination System (NPDES) general permit for small MS4s. The U.S. Environmental Protection Agency (EPA) oversees the NPDES Phase II permitting program.  In order to comply with the program the Town must follow six Minimum Control Measures, which are implemented through a series of Best Management Practices (BMPs):

  1. Public education & outreach
  2. Public involvement & participation
  3. Illicit discharge detection & elimination 
  4. Construction site stormwater runoff control 
  5. Post-construction stormwater management
  6. Pollution prevention & good housekeeping
 The Town of Framingham is a member of the 
Central Massachusetts Regional Stormwater Coalition (CMRSWC). 

The CMRSWC is a group of communities working together to address municipal stormwater management.   As neighbors, we share stormwater systems, surface water resources, and the need to ensure the long-term protection of these resources.
The regional initiative benefits each community by providing a framework and tools for a successful and sustainable stormwater management program.
