Stearns County septic services.

Stearns County administers the only septic (SSTS) program in the county; MPCA's 2025 annual report lists no separate city or township program. Your permit runs under the county's own SSTS ordinance — required by Minn. Stat. § 115.55 and allowed to be stricter than the state rules — and the county must give you a written list of any differences from those rules on request (subd. 2(c)); ask before designing. The report lists the county among the 59 requiring a compliance inspection at property transfer: expect the system checked when you buy or sell.

The Mississippi River from the County State-Aid Highway 7 bridge at St. Cloud to the northwestern boundaries of Anoka and Champlin is a designated state wild and scenic river (Minn. R. 6105.0800). Inside its mapped land-use district, DNR-certified local ordinances impose the district's own standards, including a septic setback of 75 to 150 feet from the river by classification in place of the ordinary shoreland setback (Minn. R. 6105.0120). Check whether the parcel sits inside the district before planning a system.

The dominant constraint here is seasonal soil saturation close to the surface (60.4% of rated soils), followed by water standing on the surface (12.7%). NRCS's Minnesota-specific ratings put 61.1% of rated ground in the very or extremely limited classes for a conventional below-grade trench and 55.8% for a mound.
