Johnson County Wastewater responding to a manhole overflow near 11000 Oakmont Street in Overland Park

Johnson County Wastewater, in collaboration with the Johnson County Department of Health and Environment, is actively responding to an overflow of a manhole adjacent to a creek near 1100 Oakmont Steek in Overland Park. The overflow was discovered around 9:30 a.m. on Tuesday, June 23. The overflow was caused by a blockage in the sewer line due to a buildup of grease. Sanitary sewer service in the area is not affected.

The overflow has been resolved. The main line has been cleaned and crews are working to clean up the area to prevent further contamination, and JCW's water quality lab team will be testing the water in this area.

JCW has posted 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 the streamway cleanup is complete.

Notice for the public

Out of an abundance of caution, due to a potential risk of E. coli exposure, JCDHE advises individuals to have no contact with standing 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 wants to remind the public that fats, oils and grease should never be poured down the drain, including in toilets. Please properly dispose of all fats, oils, grease and wet wipes into the trash and/or recycle oil at the Johnson County Household Hazardous Waste Facility.
