In recognition of the completion of Groton Utilities’ Water Treatment Plant construction project you are
cordially invited to a celebratory ribbon cutting ceremony taking place on June 10, 2022 at 11:00 am.
The construction of the new plant began in late 2017 and was completed in March of 2022. This $54
million project was the largest project that has been funded through the State of Connecticut’s Drinking
Water State Revolving Fund (DWSRF) program and the first project to receive state grant funds from the
DPH’s Public Water System Improvement Program.
The new main DAF (Dissolved Air Flotation) building is approximately 20,000 square feet and is where
the primary filtration functions occur. The new filtration plant can process 12 million gallons of water
per day. In addition, two new elevated water storage tanks were constructed, both of which can hold up
to 1.1 million gallons of water in reserve.
Groton Utilities provides water to approximately 45,000 people daily.
We request that you RSVP to gucommunications@grotonutilities.com by Friday, May 27th
