Septic System Permitting

The first step is to download and complete the Subsurface Sewage Treatment System (SSTS) permit application.
After the SSTS application is received staff will:

• Review the design, clarify details with the designer if necessary
• Verify soils on site with the designer if requested
• Issue the Permit To Construct the SSTS or return the application if more information is needed
• If it is determined that the design does not conform to the requirements of Ordinance 55 the owner is notified and the application is returned
• An owner may choose to apply for a Variance to be heard before the St. Louis County Board of Adjustment
• Appropriate forms and instructions on the variance process will be provided

Most common forms needed:   

• SSTS-Residential-Application.pdf 

• SSTS-Permit-Fees.pdf

• Board of Adjustment Schedule and Deadlines
