New Septic System Installation in Marion, MT

New Systems in Marion

Most new homes in the Flathead Valley go up outside a sewer district, which means a new septic system is part of the build. We install complete residential septic systems across the valley: the tank, the lines, the drain field or whichever treatment system the ground calls for, and the Flathead County permit that has to come first. New construction here follows Montana DEQ rules through Flathead County Environmental Health, and the design depends on a site evaluation of your lot’s soil and groundwater. On a cobbly bench above the valley a conventional gravity system may be fine; on a lakeshore lot, a river bottom near Evergreen, or a parcel with shallow groundwater, the county may require a pressure-dosed, elevated sand mound or other engineered system, and the price and the layout change with it. We walk the lot with you before you commit, tell you what the ground will likely allow, handle the application and the inspections, and build a system sized for the house you are actually building, not the one the old permit described. We also replace systems that are past saving, on the same permit path.

Septic service in Marion

Marion is the far west edge of the ground we cover, about 25 miles out from Kalispell on Highway 2, where the valley has given way entirely to timber, ranch land and lakes. It is a small community spread around Little Bitterroot Lake, McGregor Lake and Bitterroot Lake, with year-round homes along the highway and a lot of cabins and second homes on the lakeshores and up the gravel roads into the hills. There is no sewer in Marion and never will be; every home is on a well and a septic system. Marion septic is remote septic. Many of the lake cabins were built decades ago with small tanks set close to the water and short fields squeezed onto rocky lakeshore lots, and they sit empty for months before a full family arrives in July. The hill properties have long gravel driveways, big snow loads and deep frost, and tanks that nobody has seen since the house was built. We make the drive. We pump, repair, inspect and install septic systems around Marion and the west valley lakes, we bring the hose length for a cabin below the road, and we know what freezes out here and when. Tell us where the property is, how the road in looks, and what the system is doing, and we will give you a straight answer and a price before we start.
