What does CSO mean?
Combined Sewer Overflow (CSO) is an overflow occurs in a Combined Sewer System (CSS). Combined Sewer System is a type of sewer system designed to collect storm water runoff, domestic sewage, and wastewater in the same pipe. Under normal conditions, combined sewer systems transport all of their wastewater to a sewage treatment plant, where it is treated and then discharged to a water body. During heavy rainfall or snow melt the volume of wastewater can sometimes exceed the capacity of the treatment plant. When this occurs, untreated water discharges directly to nearby streams, rivers, and other water bodies. The location of the discharge along with the actual discharge event is called the Combined Sewer Overflow (CSO).
