The Water Pollution Control Facility, operated by Veolia Water North America, is a division of the Public Works Department and reports to the Director of Public Works.

The Water Pollution Control Facility provides preliminary, primary, and advanced secondary treatment of all sanitary sewer waste. The treatment of sanitary sewer waste is subject to state and federal NPDES permit requirements. No effluent violations were recorded during the past year.

Facility personnel provide operation and maintenance of the WPCF, nine pumping stations, and preventive maintenance of 110 miles of sewer lines. Facilities personnel performed 955 markings of underground sewer utilities as outlined in the "Call Before You Dig" program and performed 23 inspections of new sewer connections to the Town’s sanitary sewer system.

In addition to these duties, facility personnel provided preventive and corrective maintenance of all mechanical systems at the town swimming pool and eight emergency generators located throughout the town.

Facility personnel also celebrated 5,964 days without a lost time accident this past year.

The secondary treatment process at the facility was upgraded in 2005 to allow for the reduction of nitrogen in the wastewater. The reduction of nitrogen in the wastewater is required by the Connecticut Department of  Environmental Protection to achieve water quality standards for Long Island Sound. This past year the facility exceeded its allowable discharge limit resulting in the Town having to purchase $4,971 of nitrogen credits from the Connecticut Department of Environmental Protection.

Projects completed this year included cleaning of both primary and secondary digesters, upgrade of the ultra violet disinfection system, and replacement of the gravity thickener center drive mechanism.
