The Erie County Sewer District No. 3 is soliciting sealed bids for Phase 2 expansion of the Southtowns Advanced Wastewater Treatment Facility. The scope includes constructing two new UNOX biological‑oxygen reactors, a new influent aerated channel, four clarifiers with flow‑distribution structures, a new Return Activated Sludge (RAS) pump station with tunnel extension, and extensive upgrades to existing process equipment, civil, structural, mechanical, electrical, and environmental remediation work (asbestos and lead‑based paint removal). The project will require coordination of heavy civil construction, process equipment installation, hazardous‑material abatement, and integrated utility upgrades.
• New UNOX reactors, clarifiers, and RAS pump station installation – specialized wastewater‑treatment equipment.
• Demolition, asbestos/lead‑based paint abatement, and extensive civil/structural concrete work.
• Full mechanical, electrical, instrumentation, HVAC, plumbing, and fire‑protection upgrades.
• Requires experience with large‑scale municipal wastewater plant projects, environmental compliance (NY SPDES permits), and joint‑venture or subcontractor management.
