N.Y. wastewater treatment plant installs AD system

The Watertown Pollution Control Plant in northern New York is being modified to replace the existing sewage sludge incinerator with enhanced anaerobic digestion technology through funding from the New York State Energy Research and Development Authority and the Gov. Andrew Cuomo’s Regional Council Initiative.

NYSERDA’s funding will cover the preliminary design and final design phase engineering services, including conceptual layout, product marketing, preparation of a preliminary design report and final design and preparation of documents.

By replacing the existing sludge incinerator, the plant will eliminate the need for auxiliary incinerator fuel and transportation of ash to the landfill. Additionally, the modification is projected to save the city $250,000 and replace 28,000 gallons of fuel oil per year.

“Our regional plan recognizes the economic importance of greener, cleaner processes, from business operations to wastewater treatment plants,” said Garry Douglas, co-chair of the North Country Regional Council. “Thanks to Governor Cuomo and the City of Watertown, we will now have yet another project in the North Country that highlights the possibilities and implements the vision.”

“The North Country Regional Economic Development Council identified ways to capitalize on the region’s assets and to build one of the greenest energy economies in the state,” said Anthony Collins, president of Clarkson University and co-chair of the North Country Regional Council. “Projects like this recognize that we need to invest in clean energy sources as well as address an aging infrastructure to support additional development.”

The current facility produces 10,000 cubic feet of methane gas each day from its two digesters. This gas is then used as the main fuel to heat the digester complex.
