Our Mission Statement:

We are a Prideful Team that responsibly safe-guards and efficiently operates our most valuable resource. We provide a dependable supply and ensure the highest quality of treated drinking water is reliably delivered for protection of the health and well being in our community 365 24/7.


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 96 miles of water mains which feeds (3) storage tanks (one 4.5 million gallons and two 1.1 gallons) that supply the system.
