The Wastewater Division collects and treats the wastewater produced by the citizens and businesses of Gillette. The Wastewater Division operates and maintains about 200 miles of sewer line and 10 lift stations. The wastewater is treated at a conventional activated sludge treatment facility with anaerobic digestion and UV disinfection.

The wastewater treatment facility (WWTF) treats an average of 3.04 MGD (million gallons per day). We also reclaim the solids which are composted and sold to the public as the Class A biosolids product known as Stonepile Soil Amendments.

The Stonepile Soil Amendments are available for purchase $20 per cubic yard for Biosolids, and $20 per cubic yard for Yard Waste compost.

Please check in advance for availability by calling (307) 686-5274.
