The Boston Water and Sewer Commission (BWSC) was created to maintain and improve the long-term quality and reliability of water and sewer services in the City of Boston. Today, BWSC’s primary goals are cost control, efficient delivery of service and environmental protection. Accordingly, it is necessary for BWSC to maintain and improve the water distribution and sewer systems, to establish and administer a sound billing and collection system that is fair and efficient, and to maintain a strong financial structure.

The Enabling Act

BWSC was established in 1977 pursuant to a "home rule" petition enacted by the Massachusetts State Legislature as the Boston Water and Sewer Reorganization Act of 1977, Chapter 436 of the Acts of 1977 ("the Enabling Act"), on July 18, 1977. In accordance with the Enabling Act, ownership of the wastewater collection and stormwater drainage system and the water distribution system was transferred from the City of Boston's Department of Public Works (DPW) to BWSC in August of 1977. The Enabling Act also provides for the establishment of a three-member Board of Commissioners.

BWSC is required by the Enabling Act to develop a three-year Capital Improvement Program (CIP) annually. In keeping with this mandate BWSC has substantially rehabilitated and improved the systems.

Board of Commissioners

BWSC is overseen by a three member Board of Commissioners appointed by the Mayor of Boston, subject to approval by the City Council. The primary responsibility of the Board is to ensure the sound economical and efficient operation and maintenance of the systems and to ensure the highest quality services to the City of Boston. The Board of Commissioners is also responsible for setting clear financial and operational policy directives.


BWSC consists of four divisions: Executive, Engineering, Administration and Finance. Click to view the Commission's Organizational Chart.
