ABOUT THE TOUR

The present day wastewater treatment plant is designed to treat an average daily flow of 34 million gallons per day (mgd) with a peak design of 56 mgd. The City has negotiated with the Environmental Protection Agency (EPA), a CSO bypass order in which the Wastewater Treatment Plant will take up to 80 mgd. Flows in excess of the secondary capacity of the plant will go through primary treatment, bypass the aeration tanks, and go directly to chlorination and dechlorination.

There are 11 pumping stations within the City of Manchester. Ten of these stations convey wastewater to the main influent pumping station. All flow is pumped to the Plant from the main pumping station called the Crescent Road Pump Station Annex. The sequence of treatment processes is further explained by visiting the below links.

A “Facilities Plan” was completed in 2009 that sets the road map to increase the plant’s hydraulic capacity.  Upgrades are ongoing with secondary clarifiers being completed in 2010 and the Fluidized Bed Incinerator in 2011.  The Grit Collection System upgrade is slated for completion in 2013 with along with all of the 11 Pump Stations.  Learn more.
