Wastewater Division

The City's sewage treatment plants, located at 450 Environmental Drive, operate 24 hours per day and are permitted to treat 12.4 million gallons of wastewater each day with a maximum excess flow capacity of 24 million gallons per day.

Currently, the average daily flow through the treatment system is 5 to 6 million gallons per day. The plant is fed by nearly 300 miles of sewage collection lines. The entire collection system has 50 sewage lift stations that pump sewage from low-lying areas to the plant via sewer collection lines.

NPDES Permit

The National Pollutant Discharge Elimination System (NPDES) permit program, created in 1972 by the Clean Water Act, helps address water pollution by regulating point sources that discharge pollutants to waters of the United States. 

The permit provides two levels of control: technology based limits and water quality-based limits (if technology-based limits are not sufficient to provide protection of the water body).  In states authorized to implement Clean Water Act programs, EPA retains oversight responsibilities. Currently 47 states and one territory are authorized to implement the NPDES program.

East Creek Sewer Separation Project

The U.S. Army Corps of Engineers-St. Louis District and the City of Belleville have signed an agreement to begin work on the East Creek Sewer Separation Project. 

The East Creek Sewer Separation Project News Release explains the details behind this project to rehabilitate local infrastructure.

Construction of the East Creek Sewer Separation Project for the City of Belleville was also partially 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 the separation of storm sewers from the sanitary sewer system and the construction of two detention ponds. Once complete, it will improve water quality for area residents and businesses in the East Creek watershed area of Belleville by reducing potential sanitary sewer overflows. 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.
