Project: State Line Pump Stations & Forcemain
Project Notice - updated May 21, 2025:
-
There will be construction equipment near I-435 and State Line Road throughout May.
-
Intermittent lane closures in State Line Way, near 104th Street are expected throughout May.
-
Temporary Trail Closure:
-
A new sewer force main pipe is being installed across/under Indian Creek (near the Indian Creek Trail south of Indian Creek, at State Line Rd and I-435) and will continue for approximately 2 to 3 weeks.
-
A temporary trail, paved with gravel has been put in place for access. However, it may be closed at any time to restore the concrete paving or other needs by the construction team. Please follow all safety and signage notices. Weather permitting, the trail is scheduled to reopen permanently by June 13.
-
We apologize for the inconvenience. We are fully aware that the trail does not have a good alternative safe route for detouring and will make every effort to move as quickly as possible to get the construction work done safely and the trail restored.

-
We appreciate your patience as we work to safely complete the project. For the safety of the public and our workers, please follow all signage and safety guidelines.
Project Purpose:
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.
