The $54 million project, which received a $15 million state grant, includes constructing a new nearly 20,000-square-foot building for treating and processing water and two new above-ground storage tanks, while repurposing elements of the 1939 facility, according to Groton Utilities. R.H. White Construction Co. of Massachusetts is the general contractor on the project. The water treatment plant project includes upgraded mechanical and electrical systems. Rick Stevens, manager for Groton Utilities in the water and wastewater division, said the upgrades to the plant, which are expected to be completed next year, incorporate measures for redundancy, resiliency and energy and water conservation, as well as new technology for processing and treating water.
