Septic & well regulations in Todd County, MN
Todd County is located in the North Central Lakes Country region of Minnesota. Todd County sits at the meeting of the Alexandria moraine and the sandy outwash plains to the north and east, so soils range from loam and clay loam on the rolling uplands to loamy sand along the river corridors. Percolation varies widely over short distances, which makes site-specific borings essential. Understanding local permit requirements and soil conditions is essential before installing, repairing, or inspecting a septic system.
Permits & Requirements
New Installation
Todd County requires an SSTS permit before a new system is installed outside sewer service in Long Prairie, Staples, and the smaller cities. The application must include soil borings and a design from an MPCA-licensed designer establishing three feet of unsaturated soil above the saturated zone. Shoreland districts around the county's lakes and along the Long Prairie and Crow Wing rivers add setbacks from the ordinary high water level. An MPCA-licensed installer must construct the system, and the county inspects it before backfill.
Repair
Todd County issues the repair permit before work begins, covering tanks, beds, and distribution changes alike. An imminent threat to public health and safety must be corrected within a month; a separation deficiency has ten months. The county's mix of dairy farmsteads and lake cabins means repairs range from a straightforward tank swap to a complete relocation. Drywells and seepage pits found during the work must be abandoned rather than reconnected.
Inspection
Compliance inspections by MPCA-licensed inspectors are required for building permits that add bedrooms and for many land use approvals in Todd County. Certificates of compliance are valid three years on existing systems and five on new construction. Seasonal cabin owners should still schedule the state-required three-year tank measurement, since solids accumulate regardless of how many months a year the cabin is occupied.

Soil & Terrain Characteristics
Todd County sits at the meeting of the Alexandria moraine and the sandy outwash plains to the north and east, so soils range from loam and clay loam on the rolling uplands to loamy sand along the river corridors. Percolation varies widely over short distances, which makes site-specific borings essential. Peat and muck fill the wetland basins between the hills and rule out conventional drainfields on those parcels.
County-Specific Considerations
The county's mix of lake recreation and dairy and crop agriculture means septic work here spans both seasonal cabins and working farmsteads, with very different design considerations. Sandy soils along the Long Prairie and Crow Wing rivers accept effluent quickly but offer limited treatment, so separation is enforced carefully. Arsenic testing is advisable on newly drilled wells given regional groundwater conditions.
