DEP safe drinking water regulations require that distribution storage facilities be covered to protect the quality of treated drinking water. MWRA has embarked on a system-wide program to eliminate open distribution storage reservoirs from active service and replace them with secure covered tanks.
Two 10 million-gallon buried drinking water storage tanks are being constructed in the East end of the existing Blue Hills reservoir. These tanks are critical to the MWRA’s Southern High water service area, which would be served by the proposed covered tanks. It is one of the only remaining areas in the MWRA system that has no significant distribution storage to ensure a safe and reliable public water supply.
The new water storage tanks will be filled with MWRA drinking water and will serve Quincy, Milton, Brookline, Roxbury, West Roxbury, Jamaica Plain, Roslindale, Mattapan and Hyde Park. The water tanks will store safe drinking water for consumption and fire protection in the event of a pipeline break or other water supply emergency.
Since the events of September 11, 2001, MWRA has become more security conscious and has increased the priority of constructing this and other covered storage projects. In November 2001, legislation was filed to accelerate the project by allowing MWRA to use the design/build process to construct this facility. It was enacted in September 2002.
The existing reservoir was constructed in 1950s and was removed from active service in 1981 due to contamination from birds and animals. The reservoir is currently used as a non-potable emergency supply.
The design/build contract was awarded in November 2006 for a cost of $38 million including $9.5 million for site enhancements and wetlands mitigation. Construction will began in Spring 2007 and should be completed in Spring, 2010.
The Blue Hills Working Group was formed in 1997 to review alternatives and met periodically for 3-1/2 years to provide input to MWRA. The Working Group includes representatives from the Department of Conservation and Recreation, Quincy, Milton, Braintree, Trailside Museum, Friends of Blue Hills, Water Supply Citizens Advisory Committee, MWRA Advisory Board, and St. Moritz Stables.
This proposed alternative was selected because the site:
MWRA has worked closely with various interested parties to include features that will mitigate environmental impacts and improve the look of the finished site (link to site plan):
