Tighe & Bond Evaluates Wastewater Cogeneration Project for City of Easthampton
The City of Easthampton owns and operates a 3.8 million gallons per day (MGD) wastewater treatment facility (WWTF) and currently pays for sludge removal from the site. Tighe & Bond was hired by the City to study the feasibility of a food waste/wastewater sludge AD cogeneration project at the Ferry Street WWTF.
Since Easthampton has been approached by renewable energy developers interested in developing the project, the City wanted to become more educated regarding a potential facility. Easthampton also wanted to understand the accompanying benefits and public impacts prior to entering an agreement with a developer. To that end, Tighe & Bond completed an initial site assessment and estimate of project capacity and impacts. Tighe & Bond also obtained a $40,000 grant from MassCEC under the Commonwealth Organics to Energy program to conduct a comprehensive Feasibility Study for the project.
The Organics to Energy Feasibility Study included a comprehensive overview of the following project components:
- Site history, environmental constraints, zoning
- Evaluation of volume of potentially available feedstock including wastewater biosolids and other source separated organics, preliminary chemical composition of feedstock
- Digester sizing
- Estimate of biogas and potential energy generation production
- Estimate of digestate production and evaluation of digestate
management approaches - Evaluation of operational and treatment impacts to existing WWTF
- Project permitting requirements
