The Minnesota Pollution Control Agency (MPCA) issued its latest subsurface sewage sewage treatment systems (SSTS) annual report just in time for SepticSmart Week.

The overall compliance rate of septic systems for 2020 is estimated to be 81% (505,300 systems), which is an increase from 77% in 2011. This exceeds the Clean Water Council’s strategic plan goal of 80% compliance. Systems failing to protect groundwater (FTPGW) and systems with an imminent threat to public health and safety (ITPHS) have both decreased over the last 10 years.

The SSTS annual report is compiled with information submitted by local government units (counties, cities, and townships) that administer installation permits and septic systems inspections. To learn more about the number of permits issued, inspections conducted, and septic system professionals licensed and certified in 2020, visit the MPCA’s SSTS annual report page.
