New Septic System Installation in Somers, MT

Building on a lot outside the sewer line, or replacing a worn-out system? We handle the county permit, the site evaluation and the install.

New Systems in Somers

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 Somers

Somers sits at the very north end of Flathead Lake on Somers Bay, about ten minutes south of Kalispell on Highway 93, an old rail and sawmill town that has become a quiet lakeside community of year-round homes, cabins and a growing number of new houses on the slopes above the bay. Some of the town is served by a local sewer district; the homes along the lakeshore east and west of the bay, the places up the hill toward Highway 82 and the farm and acreage ground north toward the Lower Valley mostly run on their own septic systems. Somers septic is a mix of lake and valley floor. Near the bay the ground is low and wet, with groundwater close to the surface in spring and a drain field that has to make do with little dry soil. Up the hill the soil is cobbly glacial gravel that drains fast. And because Somers has long been a place people retire to or keep a cabin in, we see a lot of older systems, often undersized, often with no records, on properties now changing hands to buyers who want an inspection before closing. We pump, repair, inspect and install septic systems in and around Somers. Tell us where the tank is and what is going on and we will give you an honest answer and a real price.

Common Septic Issues in Somers

The septic problems we see most around here, and how we handle them.

Low, wet ground near the bay

The ground around Somers Bay sits low, and the water table rises close to the surface every spring. A drain field there is working in wet soil for weeks at a time, so keeping solids out of it with on-schedule pumping is the single best thing an owner can do.

Older cabins that became year-round homes

Plenty of Somers places started as summer cabins with a small tank and a short field and are now lived in full-time. Those systems are undersized for the load. We pump them more often, inspect the field honestly, and tell you when it is time to plan a replacement.

Sewer or septic, and which lots are which

Part of Somers is on a sewer district and part is not, and the line between them is not obvious from the street. If you have no sewer charge on a bill and do not know where your tank is, we locate it and tell you what you have.

New Systems in Somers: FAQs

Do you cover Somers?
Yes, and it is a short run from our Kalispell yard. We cover Somers Bay, the lakeshore on both sides of town, the hill above Highway 93 and the Lower Valley ground north along Highway 82. Call or text and we can usually get to you quickly.
How do I know whether my Somers home is on the sewer district?
Look for a sewer charge on your utility bill. If there is none, you are on a private septic system. We can locate the tank and confirm what you have, which is worth knowing before you sell or add a bedroom.
My cabin was built in the sixties. Can the old system keep going?
Often, with care. We pump it on a shorter interval, check the baffles and the tank for cracks, and watch the field each visit. When it is time to plan a replacement we will tell you plainly, and we handle the county permit when that day comes.
Do I need a permit for a new septic system in Flathead County?
Yes. Every new or replacement system goes through Flathead County Environmental Health under Montana DEQ rules, and the design depends on a site evaluation of the lot. We handle the application, the evaluation and the inspections as part of the install.
How long does a new system take?
The install itself is usually a few days once the permit is in hand. The permit and site evaluation add time ahead of that, and the county’s review time varies with the season. Frozen ground limits test pits in deep winter, so if you are planning a spring build, start the septic application in the fall.
Will my lot need a sand mound or an engineered system?
It depends on the depth to groundwater and the soil. Lots on the valley floor, near the river, or on the lakeshore often do; benches and hillsides with deep gravel often do not. We can look at your lot and the county records before you buy and tell you which way it likely leans, so there is no surprise in the budget.
Can you replace a system that has failed?
Yes. A replacement follows the same permit path as a new system. If the old field has failed we will tell you honestly whether a repair is realistic first, and if not, we design and build the replacement the ground and the county call for.
