Septic Tank Ordering Steps for Flathead County, MT
STEP 1
Land Survey Approval
The first step to getting your septic tank is to fill out a Land Research Request Form with the County before submitting any septic tank application. You’ll answer a few questions and fill-out some information in the form.
Next, you’ll want to go to the Flathead County Health Department website and either apply for a Residential Evaluation and Septic System Application or a Commercial Evaluation and Septic System Application. If you’re unsure if you will need a Site Review or Evaluation, you can fill out this form.
Click the button and select the application that fits your project best.
Finally, after you get approval from both departments you can complete our Get an Estimate Form. This form will walk you through each question we need answered to give you the most accurate estimate possible. Select Residential Septic Systems or Commercial Septic Systems for your precast concrete septic tank project.
The process is different depending on what county you are in. All properties need to have Land Research Request approval before anything else. After that it is up to each county on what they require.
Please call your local county for permit requirements. The above steps are for Flathead County, MT*
