Water District No. 1 of Johnson County, Kansas, (WaterOne) awarded Garney this $74 million water treatment plant project. This new, state-of-the-art facility was designed to keep up with increased demands placed on the county’s existing water treatment plants due to the area’s rapid growth over the past few years. The 10 MGD (expandable to 30 MGD) plant included the construction of two aerators, basin flow splitter, primary basin, final basin, residuals control building, operations building with membrane filters, below ground cast-in-place treated water storage reservoir, chlorine contact basin, high service pumping station, surge control facilities, chemical storage and feed facilities, electrical, instrumentation and controls, mechanical work, and site work. The project included the placement of 22,000 CY of concrete and the excavation of 1,023,000 CY of dirt. The 19-month construction schedule was extremely tight and required precise coordination and detailed scheduling.
“Construction of this state-of-the-art water treatment plant presented your team with a multitude of challenges. In summary, the project was considered a success by all project stakeholders. The success of this project is directly attributed to Garney Construction’s dedication, experience, communication skills and teamwork.”
