MWRA System Expansion

Massachusetts Water Resources Authority


MWRA Water System Expansion

MWRA recently completed two feasibility studies for expanding MWRA’s water system to the Ipswich River Basin (Beverly, Danvers, Hamilton, Ipswich, Middleton, Lynn, Lynnfield Center Water District, Peabody, Salem, Topsfield, Wenham, Wilmington) and to the South Shore area (Abington, Avon, Brockton, Cohasset, Hanover, Hingham, Norwell, Scituate, Rockland, Weymouth, and the Former Naval Air Station). The South Shore feasibility study also looked at expanding MWRA’s wastewater system to the South Shore. A third, ongoing system study is looking at expanding MWRA’s water system to communities in the Metro West area. The Metro West study currently includes 15 communities (Acton, Bedford, Chelmsford, Concord, Groton, Holliston, Hopkinton, Lincoln, Littleton, Maynard, Natick, Sudbury, Wayland, Wellesley, and Weston).

As a regional supplier of water in Massachusetts, there are opportunities for MWRA to extend water service to communities within the three study areas. MWRA’s high quality source water is a result of our highly protected, forested watersheds. These watersheds act as a buffer against many contaminants, both regulated and unregulated. Additionally, MWRA’s water conservation efforts over the last several decades have resulted in an even more resilient water supply system able to withstand drought conditions and recover following a drought. The “Safe Yield” (i.e., the maximum withdrawal that can be made continuously from a water source or sources during a period of extended drought) for the MWRA system is 300 million gallons per day.

MWRA Water and Wastewater Admission Policies

MWRA has detailed policies that address the procedures and criteria for handling requests for services to locations outside the MWRA's water or sewer service areas. Descriptions of these policies can be found on our Admission page.
