IMPORTANT INFORMATION RELATED TO COVID-19 (CORONAVIRUS)

All St. Louis County offices are open to the public. Currently, the COVID-19 Community Level is high in St. Louis County, which means facemasks are recommended inside St. Louis County buildings (and all indoor public places.)

 
Homeowner installations are allowed under the ordinance but require additional oversight. Please contact the county early to discuss for a successful installation. 

A property owner installing a SSTS to treat wastewater solely from their own dwelling or a seasonal dwelling may install their own system without a license providing the following conditions are followed:  

 
 A. Homeowner exemption will be limited to Type I and Type II systems only. 
  • Type I System: “Type I System” means an ISTS that follows a standard trench, bed, at-grade, mound, or greywater system design in accordance with MPCA rules, Minnesota Rules, Chapter 7080.2200 through 7080.2240.
  • Type II System: “Type II System” means an ISTS with acceptable modifications or sewage containment system that may be permitted for use on a site not meeting the conditions acceptable for a standard Type I system. These include systems on lots with rapidly permeable soils or lots in floodplains and privies or holding tanks.  Minnesota Rules, Chapter 7080.0040 through 7080.2240. 

B. The system must be designed by an individual licensed in accordance with Minnesota Rules, Chapter 7083.0700, Subp. B.
