The Town of Brookline provides the following information to help eliminate non-stormwater discharges to the town's municipal storm drain system. (The town regulates stormwater discharges under By-Law 8.26.) Non-stormwater discharges are flows to the storm drain that are not comprised entirely of stormwater and are major causes of:

  • Impairment of water quality and flow in lakes, ponds, streams, rivers, wetlands, and groundwater
  • Contamination of drinking water supplies
  • Alteration or destruction of aquatic and wildlife habitat
  • Flooding

Rainwater flows from the roof, driveway and street into a drain, picking up pollutants along the way

Where the Stormwater Drains

As stormwater from rain and snowmelt flows over ground surfaces, it picks up debris, chemicals, dirt, and other pollutants. Stormwater can flow directly into our rivers, brooks, ponds and wetlands, or enter the storm drain system and discharge to these waterbodies:

  • Charles River Muddy River Sawmill Brook
  • Leverett Pond Willow Pond Sargent Pond
  • Hall's Pond

Stormwater Management Plan

The Small Municipal Separate Storm Sewer System General Permit issued jointly by the EPA and MassDEP requires cities and towns to prepare a Stormwater Management Plan (SWMP). If you have any questions or would like to comment on the SWMP please contact Maria Rose at
