The Kiski Valley Water Pollution Control Authority (KVWPCA) plant was originally constructed in 1972. The current plant provides preliminary, primary and secondary treatment along with disinfection prior to the treated effluent being discharged to the Kiskiminetas River under the terms of NPDES Permit Number PA0027626.
The newly expanded wastewater treatment facility has an average daily design hydraulic capacity of 7.0 Million Gallons per Day (MGD), with the capacity to accept and treat peak flows up to approximately 31 MGD meeting the requirements of the Environmental Protection Agency (EPA) regarding combined sewer systems (CSS) and their combined sewer overflow (CSO) Control Policy.
In 1994 the United States Environmental Protection Agency published new regulations for communities and sewage treatment plants that have sewer lines that take in sanitary sewage and storm water. In the Kiski Valley area there were 31 combined sewer outfalls. These outfalls discharged rain water and sewage to the Kiski River during moderate to severe wet weather events.
The Kiski Authority was required by the PA Department of Environmental Protection to prepare a long Range CSO (Combined Sewer Overflow) Control Plan. The Authority selected the EPA CSO Control Policy "presumption" approach criteria ii through their Long Term Control Plan (LTCP) requiring elimination or capture for treatment of no less than 85% by volume of combined sewage collected in the CSS (Combined Sewer System) during precipitation events. Through sewer separation and upgrade projects in tributary communities the number of diversion outfalls has been reduced to two (2) currently thus increasing the volume of collected sewage and reducing the volume of stormwater treated at the treatment plant. Additionally, the Plant Expansion Project has provided the necessary additional capacity to meet the EPA requirements.
GIS/GPS mapping replaces the traditional construction blueprints. In the mapping below, sewer manholes are identified as red dots and the sewer lines are yellow lines.
