Update: In collaboration with Johnson County Wastewater, the Johnson County Department of Health and Environment has lifted the public health advisory to residents and businesses near 12560 State Line Road in Leawood put in place on May 22, 2025. Water quality test results indicate that bacteria levels have returned to normal.

In collaboration with Johnson County Wastewater, the Johnson County Department of Health and Environment has issued a public health advisory to residents and businesses near 12560 State Line Road in Leawood, due to an overflowed manhole that was discovered around 9:30 a.m. this morning. See the map below for impacted locations.

Crews are currently working to relieve the blockage from tree root encroachment in the sanitary sewer line. This blockage caused the overflow. JCW’s water quality lab team will be testing the waters in this area. Crews are working to clean up the area and prevent contamination into a nearby pool and pond.

Out of an abundance of caution, due to a potential risk of E. coli exposure, JCDHE advises individuals to have no contact with the contaminated water in this area until further notice. Residents are also advised to keep their pets from making contact with standing water in the affected areas. This does not represent any impact/implications to the public water system (i.e. tap water).

JCW will post signage in this area, is monitoring this location and conducting water quality tests to determine when this notice can be lifted. An update will be sent once this notice is lifted.
