MWRA Advisory: January Valve Exercise Maintenance in the Greater Boston Area

During the month of January 2024, the Massachusetts Water Resources Authority (MWRA) will be conducting water valve maintenance exercises in the following communities throughout the Greater Boston area: the City of Waltham, and the Towns of Arlington, Belmont, Lexington, and Winchester.

This work may result in discolored water but is not expected to create any pressure losses. Should the work cause discoloration, residents and businesses should run their faucets until the water returns to normal (it can take up to approximately 10 minutes).

 If you have any questions or concerns, please contact Troy Wall at (617) 305-5762 or
