MWRA

Phase 1:

The project to connect Burlington's water supply to the Massachusetts Water Resources Authority (MWRA) has been completed. Phase 1 is designed to supply one million gallons (MGD) of water per day to the Town of Burlington via the Town of Lexington. These pictures (below) show the final connection of the MWRA Phase 1 project to Burlington's Water System.

Phase 2a:

The MWRA Phase 2 project, which will extend from Burlington to Arlington, will begin construction in April 2022.

What does this mean for summer 2022?

Although the Town is connected to the MWRA, the current connection to the Town of Lexington’s water system is not large enough to allow for the elimination of all outdoor watering restrictions in the near future. In addition to Burlington’s water supply limitations, the Commonwealth is updating the mandated outdoor watering restrictions when a drought is declared (see "Current Water Ban" page).
