St. Louis County, Minnesota
Inspections for closings. Designs for new builds. The permit work in between.
MPCA-certified. Results filed with the county.
The basics
Three parts, in order. Failures are almost always the third one.
Solids sink, grease floats, the liquid between moves on. Pumping is maintenance, not repair.
Spreads that liquid evenly. An uneven one kills a section early.
The drainfield. Where treatment happens. Once clogged, it does not come back.
New builds and replacements
Sized to the soil and the bedroom count, not the house. Up here the soil is the hard part.
Setbacks from the well, the lake, the line. Wrong spot, expensive system.
Minnesota requires three feet of unsaturated soil beneath the system. Up here that is the whole problem.
Minutes per inch. Too fast and effluent hits groundwater. Too slow and it backs up.
Flow comes from bedroom count. With the soil data, that picks the system type.
Your construction permit comes out of the finished design. Start early.
Without three feet of usable soil you cannot trench, so the design builds soil upward. That is a mound. Where even a mound won't fit, it is a holding tank — pumped on a schedule, at your cost.
Eats the three-foot separation.
Counts against separation like bedrock.
Tighter setbacks. 12-month deadline on failure.
Soil work is easier before freeze-up.

Three things we do
An inspection tells you what you have. A design tells the county what you're building.
Buying, selling, or you want to know what you have.
Does this system meet code. In St. Louis County you generally cannot close without a current answer on file.
Building, adding a bedroom, or replacing a failed system.
The document the county permits from. It starts in the dirt, because the soil decides the system — not the house.
Keeping a system legal and running between inspections.
The catch-all. Lapsed permits, county paperwork, operating permit renewals, and the ongoing maintenance a system needs to stay compliant. If you are not sure what the county is asking for, this is the one.
Multi-unit, resorts, campgrounds, or anything over 2,500 gallons a day is priced per site.
Buyers, sellers, agents
No current result on file, no transfer. These are the windows that matter.
Know what you are inheriting before the money moves.
If one of these is current, you generally do not need a new inspection.
None current? You need an inspection before it can transfer.
Certificate good three years.
Sale closes. Nothing else required.
Misses a standard. Not a health threat. Good three years.
Sale still closes. Plan for replacement.
Fails. Must be replaced.
12 months in shoreland. 24 months otherwise.
Sewage reaching the surface or a water supply.
10 months. The shortest clock the county gives.
Inspect before you list. Found in September it is a plan, not a price cut.
The sale proceeds — the buyer escrows 100% of replacement cost, with a signed transfer agreement and a contractor estimate.
Frozen ground doesn't stop a sale. The inspection defers. The agreement, estimate, and escrow are still due.
Where we work
Cook, Tower, Ely, Orr, Bear River, Britt, and everywhere in between.
We travel about 40 miles out. Past that, call and we will work it out.
Designs and results are filed with the county. That filing is what your closing depends on.
Who you are hiring
Septic inspections, designs, and permit work across the Arrowhead.
Shallow soil over bedrock, high water table, a lot of shoreline. What works downstate often does not work here.
