Kalispell, Montana
Well drilling in Kalispell and the Flathead Valley
Call (406) 407-9468 or request service below. Licensed Montana water well contractors and pump techs handle the work after you request service.
New domestic wells are the core job for Flathead acreage outside city water. A licensed Montana Board of Water Well Contractors contractor supervises construction. After the hole is completed and cased, a submersible pump and pressure system usually follow so the house has reliable flow.
Most Flathead household wells use Montana’s exempt groundwater path under § 85-2-306, MCA: flow of 35 gallons per minute or less and volume of 10 acre-feet per year or less. Starting January 1, 2026, DNRC requires Form 602I (Notice of Intent to Appropriate Groundwater) before putting that water to use. DNRC notes the Notice of Intent may be filed before or after the well is drilled; authorization of Form 602I isn't itself a water right. After the development is completed and water is put to beneficial use, the owner files Form 602 (Notice of Completion of Groundwater Development) with DNRC by the completion deadline on the authorized Notice of Intent (DNRC’s guidance also describes filing Form 602 within 60 days after the development is put to use).
Flathead Environmental Health setbacks between wells and septic tanks or drain fields apply. County staff often advise getting septic approval sorted before drilling so the well head lands in a legal location. Neighboring well logs in Montana’s GWIC database are the best first clue for expected depth and yield on your parcel.
Published contractor and industry guides describe wide typical cost bands for Montana domestic wells; we don't publish a fixed price here because access, depth, casing, grouting, and pump setting change the number. Ask for an itemized estimate from a BWWC-licensed contractor after neighboring GWIC logs and site access are reviewed.
Winter frost and snow can delay mobilizing a rig. If you're building through a Flathead winter, start the conversation early so the drill schedule and DNRC filing sequence stay aligned with your building permit.
Questions about this service
Do I need a permit to drill a domestic well in Flathead County?
Drilling is performed by a BWWC-licensed contractor (or licensed driller under a contractor). Separately, most household wells use DNRC’s exempt groundwater path: Form 602I before putting water to use (from January 1, 2026), then Form 602 after completion and beneficial use. Flathead Environmental Health also enforces well-to-septic setbacks.
How deep will my Kalispell well be?
Independent summaries of Flathead County GWIC well records often place the countywide median completed depth near 190–195 feet, but your parcel can differ. Pull neighboring logs from MBMG’s Ground Water Information Center (GWIC) before budgeting.
Can you quote a price over the phone?
No firm quote without site details. Published Montana ranges are a planning guide only. Call with the parcel, access notes, and whether septic is already approved.
