Combined Sewer Overflows

Combined Sewer Overflows (CSO) Pamphlet

The combined sewer system is designed to collect water from storm events as well as normal sewage in the same pipe. The combined sewer system transports all of the sewage to the City’s Wastewater Treatment Plant, where it is treated and then discharged to the Mad River. However, sometimes during large rain storms or when the snow melts, the volume of sewage in the combined sewer system exceeds the capacity of the collection system. When this occurs, the combined sewer system is designed to overflow and discharge excess wastewater directly into the Mad River and at various points along Buck Creek and its tributaries.

These overflows are called combined sewer overflows (CSOs). At each discharge point along the Mad River, Mill Creek, Buck Creek, and tributaries, there are informational signs describing the overflow. Click here for a list of CSOs in Springfield.

Wastewater Treatment Plant Improvement History - The Springfield Wastewater Treatment Plant was originally constructed in 1935 and placed into operation with preliminary and primary sewage treatment and single stage anaerobic sludge digestion followed by a vacuum filter.

Municipal Industrial Pretreatment Program - This program regulates the commercial and industrial discharges to the collection system. Industrial wastes can harmfully impact streams, damage sewers, and interfere with treatment plant operations; so industrial customers use pollution control technologies to remove pollutants from their wastewater before releasing them into the public sewer system. The program is […]
