Relief Facilities Project
Massachusetts Water Resources Authority
The MWRA Braintree-Weymouth Relief Facilities Project has improved the Braintree-Weymouth System, MWRAs network of sewer pump stations, interceptors and siphons that serves Braintree, Hingham, Holbrook, Randolph, Weymouth and parts of Quincy.
It has transformed the way that wastewater generated by these South Shore communities is conveyed to sewer treatment and processing facilities.
INCREASED SEWER CAPACITY
The project increased the Braintree-Weymouth Systems peak flow
capacity by approximately 19 million gallons per day and streamlined the
route that wastewater takes from South Shore communities to the Nut Island
Headworks and the Deer Island Treatment Plant.
New Braintree-Weymouth System facilities significantly reduced the
risk of sewage surcharges and backups, which can be associated with sewer
facilities that cant accommodate all of their flow due to the growth
of communities, or the age or insufficient size of the sewers, or the
entry of non-sewage flows into sewers.
SYSTEM WIDE IMPROVEMENTS
Since MWRA was established in 1985, it has been working to improve and
maintain its regional sewer facilities the pipes and pump stations
that carry wastewater from communities to treatment and processing plants.
MWRAs regional sewer improvement projects, including the Braintree-Weymouth
Relief Facilities Project, enable the whole sewer system to work as effectively
The Braintree-Weymouth Relief Facilities Project protects Boston Harbor as well as the waters and land of the projects host communities. Just as
importantly, the new facilities benefits everyone who relies on the
Braintree-Weymouth System for clean, safe, reliable sewer service.
