WWTP Nutrient Removal Upgrade
CWSRF No. 4458
Construction of upgrades and improvements to the City of Pittsfield, MA Wastewater Treatment Plant (WWTP) is partially financed by the Massachusetts Clean Water State Revolving Fund (CWSRF). The CWSRF program is administered by the Massachusetts Department of Environmental Protection with joint funding from the U.S. Environmental Protection Agency and Massachusetts.
The overall objective of this project is to upgrade the Pittsfield WWTP to reduce phosphorus levels in the effluent that is discharged to the Housatonic River and meet the City’s NPDES Permit and EPA Consent Order. This Upgrade requires a multi-faceted solution, with four major components necessary to achieve compliance: Tertiary Treatment Upgrade, Sludge Dewatering Upgrade, Biological Process Upgrade, and Secondary Clarifiers Upgrade. This project will provide water quality benefits for the surrounding Housatonic River Watershed by reducing phosphorus that causes increased algal growth in downstream waterbodies. CWSRF programs operate around the country to provide states and communities the resources necessary to maintain and improve the infrastructure that protects our valuable water resources nationwide.
