Schedule an Appointment

The Hazardous Waste Facility is open April through October, on select dates and by appointment only.


ISWR is able to accept hazardous waste items through an obtained permit with Wyoming Department of Environmental Quality (WDEQ). To stay within the permit parameters, we are limited in the quantities of hazardous waste we can collect and for a limited number of days each year. We collect hazardous waste on the 1st and 3rd Wednesday's of the month from April - October.

These appointments are in high demand, if you cannot make your scheduled appointment time please call 307-733-7678 ASAP.
