Mound Septic Installation and Replacement in Good Thunder, MN
Mankato Septic installs mounds, converts failed fields, and runs SSTS permitting for Good Thunder, Minnesota and the rural country around it. We are MPCA SSTS certified, licensed, and insured, and we work the river-bottom parcels and the farm lots south of Mankato where the sewer never reaches.
Good Thunder sits on the Maple River, and the river bottom sets the septic problem here. The low ground along the river carries a high seasonal water table that climbs close to the surface in a wet spring, and a buried field sitting in that water cannot treat or drain. A drainfield needs three feet of dry soil above the water table, and on a bottomland lot there often is not three feet to be had. That is the plain case for a mound: build the treatment up on clean sand, above the water.
Back from the river, the ground turns to the same heavy clay and glacial till that runs under the whole valley, slow to accept water even when it sits dry. So the parcel near the river fights the water table and the parcel up the slope fights the tight clay, and both point to a mound. We open a pit and read which condition your lot actually shows, because the two problems ask for different sand depths and bed sizes.
Good Thunder is in Blue Earth County, so Blue Earth County Environmental Services reviews and permits the work under Minnesota Rules chapter 7080. We assemble the evaluation, the design, and the application, file it, and meet the inspector on site. Call (507) 555-0172 for a free estimate in Good Thunder.
