Council to Vote on Sending $37M Mattabassett District Project to Referendum

The common council will vote Monday on sending the cost to build a pipeline connecting the city to the Mattabassett District Sewage Treatment Plant — $37 million — to referendum in November.

The proposed project includes building a new pump station off East Main Street in Middletown, building a pipeline along Route 9 connecting to the plant in Cromwell, and demolishing the city's sewer treatment plant on River Road, according to the Hartford Courant.

The Mattabassett District held a groundbreaking ceremony Wednesday, June 13, to mark the start of construction on a full renovation, expansion and nitrogen removal upgrade at its Water Pollution Control Facility.

The Mattabassett District currently processes wastewater from New Britain, Berlin, Cromwell, as well as parts or all of the contiguous communities of Middletown, Newington, Rocky Hill and Farmington. The plant discharges clean water into the nearby Connecticut River.

In operation since 1968, the facility treats an average of 15 to 20 million gallons of wastewater per day, with a peak flow in excess of 75 million gallons per day.
