Parks, Campgrounds & Trails


With the acquisition of Tappan Lake Marina, Muskingum Watershed Conservancy District (MWCD) chose to undertake a major renovation of the restaurant operations along with exterior and interior building and site/civil improvements. The project keeps the building footprint, but includes installing a new kitchen, public restrooms, elevator, retail store, employee offices, and family restrooms with showers. Exterior improvements include a new building façade, dining deck overlooking the lake, new parking lot with Green Infrastructure stormwater quality facilities with lighting, accessibility improvements, boardwalk, deck and patios to enjoy lake views, and improved vehicular, emergency and pedestrian circulation.

Included with the building and site improvements are upgrades to the existing water treatment plant (WTP) and distribution system along with the collection system and wastewater treatment plant (WWTP). The existing WTP and WWTP, along with the associated appurtenances, will be upgraded from 5,000 gpd capacity to 15,000 gpd new facilities with improved treatment processes for the removal of iron and manganese (WTP) and improved loading removal (WWTP). The increased discharge rate for the WWTP resulted in the authorization of a antidegradation study to verify the potential impacts to the receiving stream, in this case Tappan Lake, which is the drinking water source for Cadiz, Ohio.

Scope of Services

Environmental Design Group is providing planning, detailed design, bidding and construction administrative services for the proposed distribution system and new WTP treatment facilities and the collection
system and a new WWTP.


The Tappan Marina Improvement Project will provide a destination dining and service experience for the MWCD customers, and the utility improvements will provide improved drinking water for the marina and reduced pollutants to Tappan Lake. This project improves the customer experience and invites drivers passing by to stop and enjoy the site.
