Septic & well regulations in Clearwater County, MN
Clearwater County is located in the North Central Lakes Country region of Minnesota. Clearwater County straddles the divide between sandy morainal uplands around Itasca and the flat, wet peatlands sloping toward the Red Lake basin in the north. The upland soils are loamy sand to sandy loam that percolate acceptably, while the northern half holds extensive organic peat and poorly drained silt where conventional trenches are impossible. Understanding local permit requirements and soil conditions is essential before installing, repairing, or inspecting a septic system.
Permits & Requirements
New Installation
Clearwater County requires an SSTS permit before any new system is installed, with an application that includes on-site soil borings and a design from an MPCA-licensed designer. The county spans the Mississippi headwaters at Itasca State Park and a long list of lakes, all of which fall inside shoreland districts with added setbacks from the ordinary high water level. Designers must document three feet of unsaturated soil above the saturated zone, and on the wetter northern townships that means an above-ground system. A licensed installer must build the system and the county inspects it before backfill.
Repair
Repair permits are required for replacing tanks and drainfields or changing effluent distribution. An imminent threat to public health and safety - surfacing sewage or a direct discharge - has to be corrected within 30 days. Systems failing only the separation standard get ten months, and Clearwater County staff advise starting early because the construction season is short and licensed installers book out. Older cabin systems built around drywells cannot be brought into compliance and must be replaced.
Inspection
The county requires a compliance inspection by an MPCA-licensed inspector before issuing building permits that add bedrooms and in connection with many land use applications. Certificates of compliance run three years for existing systems and five for new construction. Clearwater County also reminds owners of the statewide requirement to have the tank measured and maintained at least once every three years.

Soil & Terrain Characteristics
Clearwater County straddles the divide between sandy morainal uplands around Itasca and the flat, wet peatlands sloping toward the Red Lake basin in the north. The upland soils are loamy sand to sandy loam that percolate acceptably, while the northern half holds extensive organic peat and poorly drained silt where conventional trenches are impossible. Water tables are high enough across much of the county that separation, not permeability, is the limiting design factor.
County-Specific Considerations
A portion of the White Earth Nation reservation extends into southern Clearwater County, where tribal environmental staff may administer septic and well permitting. Shoreland lots near Itasca State Park and Clearwater Lake face heightened scrutiny because of their proximity to the Mississippi headwaters. Rural wells in the county are usually finished in buried sand aquifers, and both iron and arsenic testing are advisable on any newly drilled well.
