About The Dedham-Westwood Water District

Thank you for allowing us to continue providing your family or business with high quality drinking water and water for fire fighting and fire protection.

The Dedham-Westwood Water District is a governmental entity created by the Massachusetts State Legislature in 1985 to operate as an independent, self-supporting unit of local government. Rates are set by the Board of Water Commissioners to cover all costs of delivering public water supply in compliance with all federal and state requirements including the federal Safe Drinking Water Act. Policy is also set by the Board, a six member commission with three commissioners from both Dedham and Westwood, appointed by the Select Boards of both Towns. Public meetings are held each month at the District’s office at 50 Elm Street in Dedham, generally the second and last Tuesday evenings each month. Dates and times of meetings are posted at both town halls and on this site. All customers are encouraged to attend these meetings.

In our continuing efforts to maintain a safe and dependable water supply, it will be necessary to continuously improve your water system. We ask that all our customers help us protect our water sources, which are at the heart of our community, our way of life and our children’s future. Important educational information on resource protection, conservation, and other current issues is included in the District’s newsletter mailed with bills or posted on our customer portal.
