City of Polo Wastewater Treatment Plant
The new water reclamation facility was built to replace the aging and deteriorating plant that was building in the 1930’s and upgraded in the 1960’s. The existing plant could not meet their ammonia effluent requirements in their National Pollution Discharge Elimination System (NPDES) permit. The new facility will now meets current effluent standards, with enough space to expand for future community needs and additional effluent standards. The new facility is designed for a 0.5 MGD utilizing the following processes: influent lift station, fine screening, grit removal, activated sludge oxidation ditch, final clarification, aerobic sludge digestion, liquid sludge storage, a lab/office/building and a headwork building. The activated sludge oxidation ditch, aerobic digestion and liquid sludge storage plant is designed to utilizes common wall construction which in turn reduces the concrete tank construction cost and the overall footprint of the facility. The project also includes upgrades to the existing wet weather flow lift station and the conversion of the tertiary lagoon into additional wet weather flow storage.
This project was designed and supervised engineers from Willett, Hoffmann & Associates.
