Water Well Drilling in the Flathead Valley
Building a home on rural land, replacing a well that's gone dry, or adding water for a shop, barn or livestock? A new well is one of the biggest — and most important — investments on a rural property. We'll connect you with a licensed Montana water well driller who works in your part of the valley.
How getting a new well works
- Research the area. Nearby well logs (depth, water level, yield) give a good preview. Montana's Ground Water Information Center (GWIC), run by the Montana Bureau of Mines and Geology, has well logs searchable by location.
- Pick the site. Wells need setbacks from septic systems, drainfields and property lines. Plan the well and septic together on new builds — Flathead County Environmental Health can explain local requirements.
- Get on the schedule. Drillers in growing areas are often booked out, especially spring through fall. Call early.
- Drilling and casing. The driller drills until they reach adequate water, sets steel casing, and tests the well's yield.
- Pump and pressure system. A pump, pitless adapter, wire, and pressure tank are installed, and a line is trenched to the house.
- Paperwork. Montana requires a well log from the licensed driller, and most household wells under the exempt limits still need a Notice of Completion filed with Montana DNRC to establish the water right. Ask your driller whether they file it or you do.
In Montana, water wells must be drilled by a contractor licensed through the state Board of Water Well Contractors. Ask for the license number.
What affects drilling cost
- Depth — the biggest factor. Depths vary a lot across the valley, from shallow wells near rivers to much deeper wells on benches and hillsides.
- Geology — gravel, clay and bedrock drill differently; bedrock wells take longer.
- Casing and screen needed to keep the well open and clean.
- Pump system — pump size, wire, pressure tank, and trenching distance to the house.
- Access — steep or wooded lots and winter conditions.
Typical totals for a new household well (drilling, casing and pump system) often land in the tens of thousands of dollars. See our Flathead well cost guide for ranges.
