Fields Point Wastewater Treatment Facility

The Narragansett Bay Commission required a new design for their Fields Point Wastewater Treatment Facility to reduce the total nitrogen discharged into 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. The new facility features the largest IFAS (Integrated Fixed-film Activated Sludge) biological wastewater treatment process in the world.
