Septic service in Bigfork
Septic help for Bigfork and the lakeshore and foothill homes around the north end of Flathead Lake.
Bigfork is an unincorporated community of 5,118 (2020 census) at the north end of Flathead Lake, where the Swan River runs into the lake in the middle of town. Homes spread out from the village along the lakeshore, into the foothills of the Swan Range and down the east shore.
Septic near the lake
Some of the village is served by a water and sewer district, but many homes beyond it, on the lake, along the Swan River and up in the hills, depend on septic. Lakefront lots bring tight setbacks and groundwater close to the surface, and older cabins may have systems that were put in long before current standards. If you're buying a lake place, ask for the permit history and an inspection before closing.
Where does pumped septage go?
As of 2024, septage pumped in Flathead County was disposed of by land application. That year the county agreed to have the Lakeside County Water and Sewer District build and operate a regional septage treatment facility, with a deadline to finish construction by the end of 2026, to handle up to about 40,000 gallons a day that needs pumping and treatment countywide. Licensed pumpers know where they can legally take a load.
Typical jobs
- Pumping and inspections for lake homes and seasonal cabins
