Septic systems in Carver County: the state’s count
MPCA counts 4,906 septic systems (SSTS) in Carver County in 2025, the 41st highest number of Minnesota’s 87 counties. Licensed inspectors and the county did 139 compliance inspections of existing systems that year: 2.8% of the county’s systems, against 2.11% statewide (the 12th highest share). The county issued 102 construction permits in 2025 and 2,479 from 2002 to 2025. MPCA’s table marks the county as requiring a compliance inspection at property transfer, which matches the rule on this page. The county figures include the city and township septic programs inside it (MPCA footnote).

MPCA counts all compliance inspections of existing systems, whatever the trigger (property transfer, building permit and others).
Private wells in Carver County
In 2015 about 14,681 of Carver County’s 98,741 residents (15%) got their drinking water from a private well, by the USGS estimate. That is the 78th highest share of the 87 Minnesota counties in the USGS table, and the 30th highest number of private-well users.
As we read it, this rule covers the septic system, not the well.

Soils and septic systems here
USDA soil surveys rate 98% of Carver County’s rated land “very limited” for a conventional septic drain field, 2% “somewhat limited” and 0% “not limited”, the 22nd highest “very limited” share of 85 Minnesota counties with survey data. The most common limits: slow percolation (dense or clay soil) on 91%; a high water table (saturated soil near the surface) on 89%; ponding on 17%.
Where soils are limited, inspections more often find drain fields that sit in seasonally wet soil, and replacement systems are often mounds or other engineered designs. A county-wide rating, not a test of one lot: a site evaluation decides.
