The Weston Reservoir is part of the greater Boston’s water supply maintained by the Massachusetts Water Resource Authority. Used only as a backup source, it is fed by the Wachusett Aqueduct and intermittently by the Sudbury Aqueduct.
Until the 1960s, the Weston Reservoir was the main receptacle, receiving water from the Wachusett Reservoir via the Wachusett Aqueduct, the main conduit used to deliver water to the greater Boston’s water system. At that time, it carried 300 million gallons of water each day. The Cosgrove Tunnel replaced it in 1965 at the primary water transmission aqueduct. 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 MWRA’s new MetroWest Water Supply Tunnel. The MetroWest Tunnel extends east 18.6 miles from Walnut Hill to Weston. During that shutdown, the Wachusett Aqueduct was the primary method of transmission of about 240 million gallons of water per day. It remains a backup connection to underground storage near the Massachusetts Turnpike in Weston as well as the0 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 open reservoirs are maintained only as emergency backup supplies.
