As a homeowner, if you’re not on municipal water and sewer services, you are responsible for maintaining your septic system. Proper design, construction, and maintenance of a septic system are essential for the health of your system and your family.

Big Sky Watershed Corps member, Jillian Henrichon, explains the basics of proper septic maintenance and their importance to keeping our waters clean.

The EPA lists four things you can do protect your septic system:

  • Inspect your system every year and pump the tank every 3-5 years, or as necessary
  • Use water efficiently
  • Don’t dispose of household wastes in sinks or toilets
  • Care for your drain field

Septic systems in Montana must meet state, city, and county regulations. Some regulations include having a drain field at least 100 feet away from the nearest 100-year floodplain and the bottom of the drainfield 4 feet above the 100-year flood elevation. Get in touch with your county health/sanitation department to learn about requirements and permits that you will need to install a new septic system.
