Water and sewer in Lenexa
Lenexa is served by WaterOne for water and Johnson County Wastewater (JCW) for sewer (City of Lenexa). That means WaterOne’s water-quality report is the one that applies to your water heater and fixtures: its 2026 Water Quality Report lists average total hardness of 135 ppm (range 110–157), about 7.9 grains per gallon. That’s hard water, so expect sediment in tank heaters and scale in tankless units over time. WaterOne’s administrative office is in Lenexa, on Renner Boulevard.
In the Johnson County Wastewater (JCW) service area, which includes Overland Park and Lenexa, the service lateral from your house to the public main is private property. The homeowner is responsible for maintaining, repairing and replacing it, including its connection point on the public main. JCW asks that you or your plumber call JCW at 913-715-8520 before a lateral is repaired or replaced.
Two JCW programs are worth knowing about if your lateral needs work: a Street Restoration reimbursement of up to $6,355 when a qualifying lateral runs under a paved public street, and a Backup Prevention Program for homes with confirmed capacity-related backups. See who owns the sewer lateral.
