Belleville's Wastewater Treatment Plant was constructed in 1939 and has been upgraded every ten years as industry and population increases in the City of Belleville.
The current plant was expanded as part of the City’s Long Term Control Plan (LTCP). The expansion increased the plant's treatment capacity by 4.4 million gallons per day (MGD) to 12.4 MGD total. The additional capacity of the expanded plant could potentially serve an estimated 120,000 residents, setting the City up for future residential, commercial, and industrial growth.
