The new, larger wastewater treatment plant will provide sanitary sewer service for the newly renovated marina building and additional buildings within the complex and will provide a higher quality effluent than the existing wastewater treatment plant.

Tappan Lake Marina Wastewater Treatment Plant and Sanitary Sewer

Environmental Design Group provided civil and environmental engineering to design the sanitary sewer and wastewater plant design for this project. In addition, the project team provided the Anti-degradation Study and National Pollutant Discharge Elimination System (NPDES) permit application to allow the new wastewater plant discharge into Tappan Lake.

The renovation of the Tappan Marina building is a part of a $6 million renovation project developed by the Muskingum Watershed Conservancy District. The plans call for development of a new restaurant on the main floor of the marina featuring seating for 250, including more than 100 seats on a covered outdoor deck overlooking Tappan Lake. The lower level of the marina will be redeveloped to make it easier and more accessible for the public to get to their docks, rent boats and buy fuel, bait, snacks and boating supplies.

A new sales and showroom building for boat sales is planned next to the main marina building. In a separate project, a new service building will be constructed on the north side of U.S. Route 250 to handle the area’s boat and storage need.

A new wastewater treatment plant is planned, which will service the marina complex as well as the Tappan Volunteer Fire Department station north of Route 250. The design of the new WWTP, planned improvements to the Tappan Marina building, including the expansion of the existing restaurant, required MWCD to proceed through the Anti-degradation Study process as outlined in the Ohio Administrative Code (OAC) Chapter 3745-1-05.
