Sewer Division

Sewer lines are underground and out of sight, few know of the efforts of the Division.  The Sewer Division is not only tasked with keeping those lines flowing freely, but also with keeping lift stations operational which are part of the sanitary system. 

WASTEWATER TREATMENT PLANT (WWTP)
The plant serves approximately 1/2 of the residents of Shiloh and 3/4 of the residents of O'Fallon.  The Caseyville Township plant serves the remainder of O'Fallon residents. 

Construction of Wastewater Treatment Facility Improvements Phase II to the City’s Wastewater Treatment Facility, located at 10378 Rieder Road, Lebanon, IL 62254 were financed by the Clean Water State Revolving Fund (SRF). The SRF program is administered by the Illinois Environmental Protection Agency and receives a portion of its money to fund these types of projects from the U.S. Environmental Protection Agency. This project includes constructing tertiary filters; sludge pump station; sludge dewatering facilities; conversion of existing package plant to aerobic digester; and associated site piping and site improvements. Once complete, it will improve water quality for area residents and businesses in O’Fallon by reducing nutrient loadings in Silver Creek. SRF programs operate in each state to provide communities the resources necessary to build, maintain, and improve the infrastructure that protects one of our most valuable resources: water.
