Butler County public works staff outlined two principal options to reduce sharply rising landfill leachate hauling and disposal costs: expand the existing leachate pond or install modular vertical evaporation towers marketed as EcoVap. Staff presented cost estimates, operational trade-offs and suggested follow-up steps including site visits to existing installations.
Jacob Riley, assistant director of public works, told commissioners the county currently pays about 8 cents per gallon to dispose of leachate and that nearby disposal sites — such as Wichita — have declined to accept the county’s leachate after lab analysis identified PFAS and other volatile organics.
