The City of Butler Stormwater Collection System

The City of Butler owns and operates a system of combined and separate sanitary sewers for the collection and transportation of wastewater and stormwater runoff to a treatment plant owned and operated by the City.  Sewers date to the early 1900s and the Wastewater Treatment Plant (WWTP) dates to the mid-1930s.

Butler’s wastewater system consists of approximately eighteen (18) miles of separate sanitary and combined sewers, with seven (7) lift stations, serving approximately 950 customers and a population of 2,700 people; and a wastewater treatment plant that provides secondary treatment with single stage nitrification (since 1996)  before the effluent is chlorinated / dechlorinated and discharged to the Big Run Ditch.

Combined sewers in the Butler wastewater collection system were designed to convey wastewater and storm water through a single pipe to the wastewater treatment plant. The combination of wastewater and stormwater runoff from the combined sewer service areas may overflow and discharge, by design, at a permitted combined sewer overflow (per an NPDES Permit) during stormwater conditions.
