If you are thinking about drilling a new water well, the first question is almost always the same: what is this going to cost? The honest answer is that it depends on how deep you have to drill and what is under your property — but there is a real, useful range. For most homeowners in the US and Canada, a complete new water well lands somewhere between $3,000 and $15,000, with the national average around $7,500 in 2025-2026.
The national range and what it means for you
Industry cost data for 2025-2026 puts a complete residential water well at roughly $3,000 to $15,000, with most homeowners paying somewhere in the $5,500 to $9,000 band. The widely cited average is about $7,500. Those are national figures, though, and the spread is wide for a reason: two homes a few miles apart can get very different quotes because the water table, the rock, and the required depth are different.
It helps to think in cost-per-foot rather than one lump sum. Drilling alone tends to run $15 to $25 per foot, while a complete system — everything you need to actually turn on a tap — runs more like $25 to $65 per foot. Since most wells land between 100 and 300 feet deep depending on your local water table, you can see how the total swings so widely.
What actually drives the price
How deep you have to drill
Depth is the single biggest lever on your quote. You pay by the foot, so a well that hits water at 120 feet costs far less than one that has to reach 280 feet. Nobody knows the exact depth until drilling begins, because it is set by where the water table sits under your specific lot — which is why a good driller quotes a per-foot rate plus an estimated depth rather than one flat price.
What is in the ground
The other big driver is geology. Softer ground drills faster and cheaper; hard rock is slow, tough on equipment, and more expensive. As a rough 2025-2026 guide:
| Ground type | Cost per foot | What it means |
|---|---|---|
| Soft soil / sand | $25–$40 | Easiest and cheapest to drill through |
| Sedimentary rock | $35–$55 | Moderate — the common middle case |
| Hard rock / granite | $55–$85 | Slowest and most expensive |
You do not get to choose your geology, but it explains why a neighbor's quote may not match yours. A local driller knows the typical ground and water-table depth in your area and can give you a far more grounded estimate than any national average. Our full well drilling cost guide breaks these drivers down in more detail.
"Drilling only" vs. a complete system
This is the part of a quote that trips homeowners up most. The drilling itself — boring the hole and setting the casing — is only about 50 to 60 percent of the total bill. A complete, working water system also includes the well casing, the pump, a pressure tank, the electrical wiring, and any required permits. If a quote looks unusually low, check whether it covers the whole system or just the hole in the ground.
| What you are paying for | Roughly how it splits |
|---|---|
| Drilling & casing | ~50–60% of the total |
| Pump, pressure tank, wiring, permits | ~40–50% of the total |
Don't forget the pump — now and later
The pump is part of any new complete system, but it is also the main thing you will replace down the road. A well pump generally lasts 8 to 15 years, while the well itself can serve 30, 40, or 50-plus years. When the pump eventually needs replacing, expect roughly $976 to $2,825, with about $1,900 being typical. Deeper wells cost more to service because there is simply more pump and pipe to pull and replace, so depth follows you for the life of the well, not just at drilling.
What about a geothermal loop well?
Some property owners drill not for drinking water but for a geothermal heating and cooling loop. The economics are different. A vertical geothermal borehole typically costs $8 to $40 per foot to drill depending on the ground, and a system needs roughly 150 to 200 feet of bore per ton of heating and cooling capacity. As with a water well, drilling is the lion's share of the loop cost — about 50 to 70 percent. The exact design depends heavily on your home, your climate, and your soil, so this is a conversation for a qualified installer rather than a number you can pin down from a national average.
How to get an accurate number for your property
National ranges are a sanity check, not a quote. Because the two biggest cost drivers — depth and geology — are specific to your lot, the only way to get a real figure is to involve someone who knows the ground locally. A few practical steps:
- Get a per-foot rate plus an estimated depth. That tells you far more than a single lump-sum number and lets you compare quotes fairly.
- Confirm what is included. Make sure the quote covers the complete system — casing, pump, pressure tank, wiring, and permits — not drilling alone.
- Ask the right people. A licensed local driller has likely drilled wells on nearby properties and can estimate your likely depth and ground type.
- Budget for permits and testing. Most states and provinces require a well-construction permit, and you will want your water tested by a certified lab once the well is in. These vary by location — check what applies where you live.
