Fredonia Wastewater Treatment Plant Upgrades

Portfolio Filter

The Village of Fredonia retained Wendel to perform complete engineering services to evaluate, design and construct various upgrades at the Village’s 3.3 MGD Wastewater Treatment Plant (WWTP). Wendel utilized NYSERDA’s FlexTech Program during the preliminary evaluation phase to identify energy operational efficiency measures that will assist the village in improving the energy and operational efficiency of the WWTP while simultaneously addressing the facility’s upgrade needs.

The following measures were chosen and included in the design of the project:

  • Replacement of the existing RAS pumps with optimally sized pumps.
  • Installation of a new WAS pump system with associated controls.
  • Replacement of the existing process water pumps with new pumps and control system.
  • Replacement of the existing DAF and centrifuge dewatering system with new dual mode thickening and dewatering belt presses and associated polymer feed system.
  • Replacement of the existing fine bubble membrane diffuser system with a new ultrafine ceramic bubble diffuser system.
  • Replacement of the existing backwash pumps with new, more efficient pumps.
  • Replacement of main aeration header from the main control building to the aeration tanks.
  • Replacement of existing grit classifier.
  • Upgrades to the existing tertiary filtration system including new automated valves, a mono media filtration system, a dual lateral filter underdrain system, air scour backwash system with positive displacement blowers and aeration piping and a fully automated control system.

Wendel is also working with grant writers and the New York State Environmental Facilities Corporation (NYSEFC) to apply for 0% interest loans, which would allow for an increased scope of work at the WWTP. The original project, with a scope encompassing $4.7 million in work, had earned $1.2 million in WIIA grant funding. In response to an increase in the project’s scope, Wendel is also working with the village and NYSEFC to apply for additional funding through WIIA grants.
