Septic System Design & Inspections

All new septic systems must comply with Minnesota Rules 7080 outlining design standards for Subsurface Sewage Treatment System (SSTS), which not only dispose of sewage, but to also treat the sewage. Typically, SSTSs are installed for new home construction or to replace older failing systems, but depending in which county you reside, or if you are located within a Shoreland Zone, your existing system may or may not need to be updated upon property transfer or to obtain a building permit. Standard types of SSTSs include at-grades, drainfields, and mound systems. The type of system required for an individual site is contingent upon the geologic and hydro-geologic conditions, most notably, the depth to the high water table.
