University Area Joint Authority – Centre County, PA

The University Area Joint Authority provides sanitary sewer collection and treatment services for the Centre Region municipalities, including the Borough of State College, that surround The Pennsylvania State University’s main campus. The population of the service area has increased dramatically over the past 20 years, necessitating expansion of the existing facilities. However, the high quality receiving stream limited the authority’s ability to discharge above 6 MGD, so HRG recommended treating a portion of the wastewater to drinking water standards and reusing it for industrial heating and cooling and other non-potable applications.

Wastewater Treatment Plant Expansion Project

The wastewater treatment plant was expanded from its 6 MGD configuration to 9 MGD through the addition of microfiltration and reverse osmosis units to produce up to 3 MGD of effluent suitable for beneficial reuse.  The project included construction of the following elements:

  • Rehabilitated Main pump station
  • Grit collection and fine screening
  • Two additional primary clarifiers
  • New A2O BNR system
  • One additional final clarifier
  • New UV disinfection system
  • New utility water sytem
  • Two new centrifuges with one polymer feed system
  • Six composting bays

Other projects HRG has completed for UAJA include:

  • Regulatory agency permitting
  • Sewage facilities planning update
  • Sewage flow study
  • Sanitary sewer extensions
  • Pump station design & construction
  • Beneficial reuse pilot test
  • Big Hollow interceptor design
  • Fuel station
  • Big Hollow Diversion pump station design
  • Developer plan reviews
  • BNR optimization study
  • Operation and maintenance manuals
  • Record drawing preparation
  • Construction inspection
  • Sanitary sewer rehabilitation
