Boston Water & Sewer Commission


Massachusetts Stormwater Management Water Quality Government / Nonprofit


The Boston Water and Sewer Commission (BWSC) manages the largest and oldest system of its kind in New England, providing drinking water and sewer services to more than one million people daily. BWSC was created by the Massachusetts Legislature in 1977, replacing separate water and sewer divisions of the city’s Public Works Department. BWSC is overseen by a three-member Board of Commissioners that is appointed by the Mayor with the approval of the City Council.
