The Ohio Department of Natural Resources (ODNR) owns and operates a wastewater treatment and collection system at West Branch State Park located at 5570 Esworthy Road, Ravenna, Ohio 44266. The existing extended aeration wastewater treatment plant has an average daily design flow of 100,000 gallons/day and has outlived its useful life. Professional Engineering services are requested to evaluate the current wastewater flows within the park, provide projected flows based on future needs of the park, and design a new wastewater treatment facility to meet the needs of ODNR and Ohio EPA. Through this project, it is anticipated that a new extended aeration treatment facility capable of treating an average daily flow of 40,000 to 50,000 gallons per day will be constructed adjacent to the existing facility to allow easy connection to the influent sewer and electric power supply. The new plant may include a flow splitter, two treatment trains, equalization basins, aeration tanks, settling tanks, sludge holding tanks, disk filters, ultraviolet disinfection and a mobile sludge dewatering system. A new building to house the disk filter, UV disinfection, blowers, restroom, and laboratory space will be included. Upon completion of the new facility, the existing treatment plant would be demolished.
