Fields Point WWTF

The Narragansett Bay Commission required a new design for their Field’s Point Wastewater Treatment Facility to reduce total nitrogen before discharging to the bay. The new design enables NBC to meet water quality requirements of the discharge permit for the wastewater treatment facility. Additionally, it provides new equipment, facilities and buildings, including a new operations building. Once completed, the facility will feature the largest IFAS (Integrated Fixed-film Activated Sludge) biological wastewater treatment process in the world.
