Water Storage Tank, Booster Pump Station, New Water Main, and Distribution System Upgrades, Spencer, MA

Town of Spencer, MA

SpencerMA water mainTata & Howard is currently providing construction administration services for a new 0.5 million gallon cast-in-place concrete water storage tank, booster pump station, approximately 12,600 linear feet of new 12-inch diameter water main, and miscellaneous distribution system upgrades. Construction of in-line isolation valves, removal of existing pressure-reducing valve (PRV) vaults, a new system wide SCADA system and new high lift pumps at the water treatment facility and well site were also included in Tata & Howard’s design. The purpose of this project is to separate the current single zone system into two pressure zones as required by an Administrative Consent Order from the MassDEP.

The creation of a two pressure zone system requires the replacement of the existing 200 horsepower (hp) pump at the Meadow Road Water Treatment Facility and 150 hp pump at the Cranberry Brook Well with lower head, high efficiency pumps and motors. The Meadow Road facility is the Town’s primary water supply source; therefore, changing of this pump requires coordination with the Department of Utilities and Facilities and the overall two pressure zone project construction sequencing to minimize the time this source is off-line.

Tata & Howard also verified the Town’s hydraulic model, which was used to select the best location for the new tank and select water main size for transmission and fire protection.  The model was also used to determine the boundary line between the two pressure zones.  A Capital Efficiency Plan™ is currently being prepared.  Assistance will be provided, as needed, for public education of the project and during Town meetings.  This project is being funded by the American Recovery and Reinvestment Act through the Massachusetts State Revolving Fund (SRF).  Due to an aggressive schedule required under the funding requirements, all design; permitting associated with planning, zoning, and wetlands; and project bidding were completed and approved within a six-month period.
