In 2019 the DPW supplied a total of 1.24 billion gallons of treated drinking water to the town. The primary source of our drinking water is four wells located in Southwick, MA. The raw water is pumped from the Great Brook section of Barne’s Aquifer and delivered to the town’s treatment plant, which consists of 12 filtration vessels, each holding 20,000 pounds of granular activated carbon (GAC). The GAC removes impurities from the well water before it is sent to the town distribution system. To guarantee the water is free of coliform, it is treated with calcium hypochlorite before it leaves the treatment plant.
The town has interconnections with Springfield Water and Sewer Commission (SWSC) drinking water source. The SWSC water source is a surface supply known as Cobble Mountain Reservoir, located in Blandford. The reservoir water flows by gravity to a treatment facility in Westfield.
The water quality of our system is continuously monitored by the Town of West Springfield DPW Water Division, Mass DEP, and U.S. EPA to determine the effectiveness of existing water treatment and if any additional treatment is required.
