Septic System Ownership in Montana

Big Sky Country is known for its stunning natural beauty, quiet rural residences, and of course, its fishing. The State of Montana works to maintain this environment by protecting its water sources. Careful management of septic systems by the Solid Waste Managment Program of the Department of Environmental Quality protects the environment and helps keep Montana beautiful.


The Waste and Underground Tank and Management Bureau is responsible for administering training, licensing, certifications, inspections, technical reviews and compliance monitoring to protect the public water supply. In addition, homeowners must apply to the Waste and Underground Tank and Management Bureau for septic system design approval and installation.

Engineers will evaluate land slope, soil quality, as well as land usage to determine the best system for the homeowner’s needs.
