Welcome to the CPWQA Facility Spotlight. Currently we are featuring the Mechanicsburg Wastewater Treatment Plant.
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.
