On Monday, April 29, 2013, the Massachusetts Water Resources Authority will be isolating a water main that serves Somerville and Brighton in support of MASS DOT’s Larz Anderson Bridge rehabilitation project in Cambridge.

The water main isolation will not cause any pressure problems, but may cause discolored water for up to 5 days in Somerville in the areas around Webster Avenue,  from the Cambridge line north to Somerville Avenue, and west to the intersection of Somerville Avenue and Beacon Street and in the Western Avenue area of northern Brighton.

The bridge work is expected to take about 2 weeks. Once completed, the water main will be reactivated, which may also cause discolored water in this area.  A similar notice will be posted at that time.

If discolored water does occur, it will result from a small amount of iron in the pipes. While it is safe for drinking, cooking and other uses, please note that ironwill stain light colored items in your laundry, especially when bleach is used. Residents should check water clarity before washing any white or lighter colored laundry during this period of work.

Please call MWRA at 617-305-5950 if you have any questions.
