Description
The City of Cincinnati is soliciting bids for the design‑build conversion of the Polk Run Wastewater Treatment Plant (WWTP) from a conventional activated‑sludge system to a Biological Nutrient Removal (BNR) process. The scope includes installing a new anaerobic selector, re‑configuring piping, adding valves and actuators, and modifying the Primary Settling Tanks to function as an anaerobic reactor while preserving operational flexibility for high‑flow conditions. All work must be performed on‑site in Loveland, Hamilton County, Ohio, and must comply with local, state, and federal regulations, including prevailing‑wage and small‑business‑enterprise (SBE) goals. Bidders must attend a mandatory pre‑bid site visit, submit electronic bids, and provide required bonds, guarantees, and insurance.
