A brief description of the institution’s sustainable wastewater systems and technologies:

Penn State owns and operates a Wastewater Treatment Plant (WWTP), and is permitted to treat up to 4 million gallons per day of wastewater. The plant is comprised of two treatment trains: activated sludge and trickling filters. The trickling filter processed water is sent through a Biological Nutrient Removal (BNR) process to reduce the nitrate levels in the wastewater. The disinfected treated water from these two parallel treatment trains is combined and spray irrigated on approximately 516 acres of farmland and forests near the University (Living Filter) and helps to recharge the groundwater system.
