Our mission at the Princeton Wastewater Treatment Plant is to protect public health and enhance the environment by treating and reclaiming water, and recycling solids. With a population of 7600, the city maintains 13 lift stations, and miles of sanitary sewers. With a jet-vac truck, crews maintain and clean sanitary and storm lines throughout the city. The city has finished an aggressive Inflow and Infiltration program study with Chamlin Engineering.
City of Princeton wastewater plant was last updated in 2000; the plant is a 2.15 million gallons per day advance oxidation treatment facility. The plant effluent passes through automated screening prior to grit removal. The secondary treatment is an advanced process, which is designed to perform nitrification, through oxidation and secondary clarification. The facility operates aerobic digesters for processing of the secondary waste sludge treatment. The 1.5 million gallons of digested liquid sludge is belt pressed for further processing and disposal by land application.
The effluent travels to Epperson Run. Epperson Run is considered to be a "no-flow" stream by the Illinois Environmental Protection Agency. It is a tributary of Big Bureau Creek.
