The overall objectives of the Boston Water and Sewer Commission (BWSC) are to ensure the delivery of high quality potable water for consumption and fire protection and the efficient collection of sewage for transport and delivery to the Deer Island Treatment Facility. Below are links to the major construction projects around the City that will improve the water and sewer system:
