Sewer Commission

The Sewer Department is managed by the Public Works Department and is operated by a private contractor.

The Town has three distinct wastewater systems:
The village of West Swanzey is serviced by an aerated lagoon treatment system with a design capacity of 160,000 gallons per day.

North Swanzey is serviced by a collection system and two pump stations. 
Wastewater in North Swanzey is pumped to the Keene Wastewater Treatment Plant.  Swanzey owns 4.7% of the Keene Plant for a capacity of 280,000 gallons per day. 

The third system is called the pass thru customers that flows into the Keene collections system for transport to the treatment plant.  The pass thru customers include Market Basket supermarket, Winchester Woods Apartments, residential and commercial customers on Matthews Road and five residential customers on Greenwood Ave.
