Wachusett Reservoir via the Weston Aqueduct (Placed in service in December 1903), which in turn received water from a connection to the Hultman Aqueduct in Southborough. Because of the construction of the water treatment facility at Walnut Hill, the Cosgrove Tunnel was shut down in 2003 in order to make the large piping connection between the new treatment plant and the MWRA’s newMetroWest Water Supply Tunnel . TheMetroWest Tunnel extends east 18.6 miles from Walnut Hill to Weston. During that shutdown, theWachusett Aqueduct was the primary method of transmission of about 240 million gallons of water per day. It remains a backup connection to two underground storage tanks near theMassachusetts Turnpike in Weston as well as the Weston Reservoir.Walkers extensively use the area around the Weston Reservoir. This reservoir is maintained along with other open distribution reservoirs (Sudbury, Foss, Brackett, Stearns, Norumbega, Waban, Spot Pond, Chestnut Hill and
Middlesex Fells ) as an emergency backup only. The MWRA's main distribution reservoirs are now covered storage facilities. The Weston Reservoir is now used by grounds crews and the MWRA's Emergency Service Unit for training and storage of emergency trucks and equipment.References
