Project: State Line Pump Stations & Forcemain

April 15, 2024: Final development plan approved, Leawood City Council

The purpose of the State Line Road Pump Stations and Forcemain project is to capture flows from the Leawood Service Area that currently drain across the State Line into the Kansas City, Missouri (KCMO) collection system and send that flow to JCW’s newly completed Tomahawk Wastewater Treatment Facility.


JCW evaluated the business case for this project and determined that the project will save JCW over $100 Million over 20 years, compared to the cost of continued treatment of all flows by KCMO. Along with these long-term savings, this project will pay for itself in approximately 6 to 7 years, providing near term financial benefits to the residents of Johnson County.
