The Water Pollution Control Authority is responsible for the operation and maintenance of the town's wastewater treatment plant, compost facility, eight pump stations and more than 205 miles of sewer lines. The wastewater treatment plant discharges 10 million gallons of treated effluent per day to Long Island Sound. More than 95 percent of pollutants are removed and 5,000 tons of sludge are generated per year, which is mixed with discarded leaves and brush and composted into an organic soil amendment.
The 2009-10 budget for the Water Pollution Control Authority is $4.8 million, and the Water Pollution Control Authority is designed to be self-supporting through the collection of sewer use fees. Revenue in 2008-09 was estimated at $4.8 million.
The Water Pollution Control Authority consists of seven volunteers - a member of the Board of Selectmen and six members appointed by the Board of Selectmen.
The Water Pollution Control Authority meets in the Honorable John J. Sullivan Independence Hall and its office, the Sewer Department, is on the first floor of that municipal building.
