B&N provided detailed design and permitting services for the replacement of an existing wastewater treatment system at Camp Otterbein facility in Logan, Ohio. The existing 40-year-old treatment plant was not consistently in compliance with the National Pollutant Discharge Elimination System (NPDES) permit limitations.
Following consideration of various wastewater-handling alternatives, B&N recommended a treatment process that simulates a natural wetland. It consists of a new extended aeration system with flow equalization, aerated sludge holding, and a constructed wetland polishing cell. This solution was selected based on its ability to maintain compliance despite the inherently wide loading fluctuations experienced at the youth camp and retreat center, lower operating costs, and natural setting that matches the outdoor appeal of Camp Otterbein.
