UPDATE 3:00 PM May 3, 2010 Community Advisory

MWRA SERVICE AREA



WATER SYSTEM FLUSHING



Based upon our hydraulic modeling, MWRA has selected very specific areas in the MWRA system and Boston and Brookline for flushing (those areas closest to the Chestnut Hill Reservoir or those areas most likely to receive the water from this source).



If a community desires to flush their system, please take precautions to limit and control the amount and velocity of water moved. The potential for discolored water or the possibility of non-representative coliform results could occur from the non-routine movement of water related to flushing (especially during this boil water order increased sampling period).



BOIL WATER ORDER STATUS



Ongoing water quality sampling continues in MWRA communities and initial sample results are beginning to be analyzed. The time frame for the lifting of the boil water order is still uncertain. Therefore it would be irresponsible for MWRA to speculate on when the boil water order will be lifted. As soon as MWRA has more precise information, we will inform our member communities.

UPDATE 7:00 AM May 3, 2010 If communities receive any calls regarding how to reach MEMA, please direct them to call 211. Community Update The 120” pipe connection has been repaired, pressurized and put back into service. Fully treated water has been distributed to the MWRA system since about 6 PM on Sunday and is expected to continue. Water pressure in MWRA service area is in typical ranges. Please remember that a Boil Water Order is in effect for the following communities until otherwise notified and water use should be restricted to essential use only. Essentially every community provided two sets of coliform/water quality samples on Sunday (thank you). Communities will collect a second round of coliform samples today. Collection of these samples will assist with resolution of the open boil water order and we again thank you for your cooperation. The MWRA Chelsea Water Quality Lab will remain open.

UPDATE 4:30 PM May 1, 2010 The leak is located at the location where the MetroWest Water Supply Tunnel meets the City Tunnel on Recreation Road. This 120-inch diameter pipe transports water to our communities east of Weston – as far north as Wilmington and south to Stoughton. Water is leaking into the Charles River at rate of over 8 million gallons an hour. MWRA crews are on site; engineers are assessing the situation to determine next steps. Updates will be posted on Mass.gov and MWRA’s website at www.mwra.com throughout the event. Back to top
