DPW Water & Sewer

The Water and Sewer Division is charged with the operation and maintenance of the Town's water supply, water treatment, water distribution, and wastewater collection systems. This entails oversight of the system's pumping and treatment facilities located at four (4) drinking-water well sites. Being a groundwater system, the Town treats its raw water with the addition of sodium fluoride for dental health, lime for corrosion control and sodium hypochlorite for disinfection. All of these treatment processes require daily manual monitoring by certified staff as well as with the department's recently installed Supervisory Control and Data Acquisition (SCADA) system. Drinking water is pumped into two (2) water storage tanks having a combined capacity of 2.8 million gallons. The wastewater system is comprised of approximately forty-four miles of gravity sewer that discharges into the treatment facility operated by the Charles River Pollution Control District. Through its recent sewer extension project, the department now operates and maintains a sewer pump station located in the Trotter Drive Industrial park area.
