DPW crew cleaning trench at Danehy Pk

Public Works maintains 78 miles of separated stormwater mains. Separated stormwater mains transport stormwater to a receiving body of water such as a river, lake or ocean.  Cambridge stormwater mains discharge to either the Alewife Brook or the Charles River.

The Sewer Maintenance Division works with the U.S. Department of Environmental Protection (EPA), the Massachusetts Department of Environmental Protection (DEP), and local community groups to improve the water quality of the Charles River and Alewife Brook.
