Welcome to the CPWQA Facility Spotlight. Currently we are featuring the Mechanicsburg Wastewater Treatment Plant.
The Mechanicsburg Wastewater Treatment Plant is an advanced wastewater treatment facility operated by employees of the Borough. It operates under a NPDES Permit based on an average annual hydraulic design capacity of 2.08 MGD.
Treatment consists of a comminutor, an aerated grit removal system, primary sedimentation, fixed-film filtration using trickling filters for BOD5 removal, anoxic tanks and activated sludge aeration tanks for nitrification/denitrification, alum addition for phosphorus removal, polymer addition as an aid in settling, final clarification, sand filters for additional denitrification and polishing, and chlorination.
The effluent is discharged to the Conodoguinet Creek through a five-mile pipeline. Biosolids generated during wastewater treatment are anaerobically digested and composted to produce an exceptional quality soil amendment that is sold to the public.
