Braintree: Tri-Town Water Treatment Plant Construction Underway

BRAINTREE, MA — Construction efforts have begun on a tri-town water treatment plant that will provide over 12 million gallons of water per day for Braintree, Randolph and Holbrook.

A groundbreaking ceremony was held at the site of the $122 million plant on Dec. 13, which was attended by Braintree Mayor Charles Kokoros. Kokoros, in addition to his role as mayor, serves as the chair of the Tri-Town Board of Water Commissioners.

As for covering the cost of the project, Braintree will pay half of the construction costs, while Randolph and Holbrook split the difference on the remaining costs. Additional funding was provided through the Massachusetts Clean Water Trust and Massachusetts Department of Environmental Protection Drinking Water State Revolving Loan Fund, according to information from the water commissioners.

The project is located on the property edge of the current Braintree Water Treatment Plant off King Hill Road, according to officials.

A tentative schedule has been established for the project, with construction stretching now until sometime in 2025. From there, testing and startup activities should start sometime in late 2025, with full operations starting in Dec. 2025, officials said.
