Water Commission



The Windham Water Works draws surface water from the Willimantic Reservoir. The Reservoir is part of a 164-square-mile watershed. The Fenton, Mount Hope, and Natchaug Rivers are the largest rivers that contribute to our Reservoir.

The Windham Water Works treatment facility, located at 174 Storrs Road, Mansfield Center, consists of a pump house and a water treatment facility. The Windham Reservoir Dam and pump house was constructed in 1885 and houses all of the pump equipment.

The water treatment facility was built in 1936 and has seen many upgrades, the latest in 1997. This building contains all the chemical applications needed to make potable drinking water. We treat an average of 2.5 million gallons per day. We maintain 84 miles of water mains which feed (3) storage tanks (one 4.5 million gallons and two 1.1 gallons) that supply the system.

Water/Sewer bills may be paid at the Windham Town Hall's Revenue Collection office, located at 979 Main Street, Willimantic. Billing inquiries should also be directed to the Revenue Collection office at 860-465-3029.

We are on-call 24 hours a day for Emergency services. We can be reached at 860-465-3086 (7:00 am to 3:00 pm, Monday through Friday). After regular hours, we can be reached at the Willimantic Fire Dispatch, 860-465-3126.
