Wastewater Treatment Plant

West Union, Ohio

New wastewater treatment plant deploying sequenced batch reactor (SBR) technology.

The Village of West Union, Ohio has a failing, antiquated wastewater treatment plant located in a valley on the south end of the Village. During the replacement of 15 lift stations throughout the Village the project scope expanded to replace the wastewater treatment plant. Built in the early 1950s, there was little information available about the existing treatment plant, so remote-monitoring flow meters were installed in the distribution system to assess the flow into the plant.

The Village purchased ten acres of land downstream of the existing plant with the intent of constructing a new plant. This required the design of a 200-ft-long, 6’ by 12’ wide box culvert in a stream, obtained a U.S. Army Corps of Engineers permit, and the valley was filled with 40 ft of fill for an entryway.

Facilities for the new plant include storm drainage, a new influent line from the existing plant, a screen building, a sludge drying, an operations building, an Aeromod Sequenced Batch Reactor (SBR), and a PAA disinfection station. Construction administration services involved meetings, shop drawing reviews, change orders, RFIs, pay requests, and budget monitoring.  The full-time Resident Project Representative services provided involved ensuring that all materials were approved and the installation proceeded per the specifications and evaluating issues that may become changes orders.
