The City of Ashland was required to remove the majority of the phosphorous from its effluent outfall being sent to Ashland creek. The two-story building consisted of a concrete lower structure, housing pumps and tanks on the dry side and Zenon filters on the wet side. The upper structure, built out of CMU and structural steel houses an electrical room, blower room and control office.
Alum pumps and a holding tank are used to pump alum into the oxidation ditch to drop out phosphorous in the clarifiers before the wastewater reaches the filtration building. Since going on-line May 1, 2002 the city has met their DEQ requirements.
Total Project Value: $4,700,000
