The village of Millersport, Ohio, located about 30 minutes from Co- lumbus, is an idyllic community with Buckeye Lake to the east and rural farms throughout the surrounding area. A well preserved portion of the Ohio-Erie Canal cuts through the center of town enhancing the colorful picturesque community of nearly 1,100 people. The Terrace Street Lift Station acts as the main lift station for the vil- lage of Millersport. Prior to 2018, the station operated with two surface pumps and two 30 horsepower (HP) submersible pumps in a wet well. The surface pumps handled normal daily operation. During rain events, the surface pumps cycled off and the submersible pumps took over. Challenge By 2017, the surface pumps had reached the end of their life cycle. Flow went through the surface pump wet well first and overflowed into the submersible pump wet well. But rags and trash settled in the bot- tom of the wet well and plugged the surface pumps when rain events ended. After each rain event, crews often spent hours unclogging the pumps. Along with decreased pump efficiency, the constant repairs added $3,000 per year in maintenance costs. Additionally, the village population didn’t grow as expected and the 30HP submersible pumps were oversized, causing inflow to the facil - ity. That resulted in increased treatment costs and added capacity to the collection system. The Millersport Water Department employs Josh Lutz as the sewer superintendent. The unreliability of the existing pumps at the Terrace Street Lift Station left Lutz wary, to the point that he felt the need to be on site there during rain events. Solution The village of Millersport needed to replace the existing equipment at the Terrace Street Lift Station swiftly. But like many municipali- ties nationwide, the Millersport Water Department works under tight budget constraints. Millersport mayor Gary Matheny and the village administrator had some previous experience with design/build (DB) projects, and wanted to look to optimize costs. DB project delivery methods allow the Owner more input into the design and equipment selection. DB also reduces the overall project schedule, which gets the Owner to the end result faster. And with that time saved, the DB process can create a lower overall price tag for the project. Ultimately, the village of Millersport worked directly with Xylem representatives to engineer a complete DB solution with full technical support. Direct procurement saved the village of Millersport $40,000 Ohio utility collaborates with Xylem to upgrade outdated lift station Design-build project provides turnkey solution in quick fashion

and allowed the village to work directly with Xylem experts during the entire process. Xylem and Stutske Construction partnered together to design a turn- key solution for an upgrade of the Terrace Street Lift Station. Stutske Construction owner Mike Stutske found flow issues on Terrace Street and in the canal. All of the sewage flows toward the Terrace Street Lift Station and when the village had heavy rains the infiltration caused backflow issues.
