Alexandria Phosphorus Removal System
Alexandria, IN
Improving safety and efficiency of wastewater treatment
Challenge: The City of Alexandria was shouldered with the responsibility of maintaining a phosphorus limit on its wastewater treatment plant discharge. It was able to meet that limit most months because of existing processes at the plant, but concentrated flow during summer months made removal difficult.
Solution: RQAW helped secure $700,000 in OCRA funding to meet recently imposed effluent limitations at their wastewater treatment plant. Failing clarifiers at the plant will also be rehabilitated to ensure the plant can treat peak flows. In response to a phosphorus limit imposed by the Indiana Department of Environmental Management (IDEM) at the wastewater treatment plant, RQAW helped fund, design, and construct the project. Part of the grant secured by RQAW allowed the City to replace additional failing components at their plant and construct a building to house equipment.
