The Washington Court House WWTP Project is upgrading its existing Wastewater Treatment Plant capacity to 15.9MGD for dry weather flow and 22.9MGD for wet weather flow.

The work on the project renovates 19 existing structures and adds 5 new structures. The renovation work consists of adding 12 pumps, 82 valves, 100+ instruments, and approximately 2,000 linear feet of ductile iron and stainless-steel pipe. The new structures include a new Influent Pump Station, Secondary Clarifier, Dewatering Structures, Electrical Feed Building, and Maintenance Shop. The most significant structure is the new Influent Pump Station, 38ft in total depth, utilizing a secant wall for earth retention as well as part of the permanent structure.

The D&M project team has worked extensively with the design team and subcontractor to propose a VE Design for repairing the existing EQ tank. This VE Design was significant in eliminating unnecessary risk for both Dugan & Meyers and the Owner in partnership with our piling subcontractor. The VE design eliminated the need for excavating 15’ deep around the entire structure perimeter and added one-sided interior walls, and redesigned foundation piles.
