Completed in spring 2022, the Tomahawk Creek Wastewater Treatment Facility project was designed to handle the increased flow due to the population growth of Leawood, Overland Park, Olathe and Prairie Village.

The new facility replaced a facility that was originally built in 1955. Prior to rebuilding the facility, 60% of wastewater had to be sent to Kansas City, Missouri.

With Tomahawk now equipped to handle the flow, this project will save almost $800 million in operating costs over the next 35 years. It was completed on time and on budget.
