(Waukesha, WI) – Waukesha County will host four Household Hazardous Waste (HHW) One-Time

are free to Waukesha County residents with proof of residency.

“Keeping dangerous materials and chemicals out of our landfills is important,” said Analiese Smith, 
Recycling & Solid Waste Supervisor for Waukesha County. “Providing ongoing collection sites and
