COMBINED SEWER OVERFLOWS
During wet weather conditions (rain, melting snow) , the combined flow of sewage and storm water is too great for the existing sewer lines to carry the flow to the KVWPCA plant for treatment. The excess flow is diverted directly to the river by the 30 diversion chambers located along the Kiski River. The flow that is diverted by the diversion chambers then is discharged to the river through Combined Sewer Outfalls. These Diversion Sewer Outfalls (total of 29) are identified throughout the Kiski Valley by Combined Sewer Overflow signs.
