First, you pay for the drill rig and the crew. These aren’t your neighbor’s DIY auger. We’re talking 40-foot-tall machines that cost $500 an hour to run, and the crew is a mix of hydraulic wizards and mud-wranglers.
Then there’s the casing—the steel or PVC pipe that prevents your well from collapsing like a cheap party streamer. Expect to spend $20 to $40 per foot just for the casing, and yes, deeper wells mean more pipe, more money.
Don’t forget the pump, pressure tank, and electrical wiring. This “finishing” package—called the well completion—can add $1,500 to $3,000. It’s the difference between a hole in the ground and a working shower.

If you live in the Texas Panhandle, you might hit water at 60 feet. In the Rocky Mountains, you’ll be drilling through granite for 400 feet. Geology is the moody artist of this project—and it always charges extra for drama.
A fun fact: the world’s deepest well is the Kola Superdeep Borehole in Russia, drilled to 40,230 feet. It cost billions, they found no gold, and the rocks at the bottom boiled at 356°F. You’ll have a much better time with your 200-foot well.
Local permits also matter. Some counties in California require a hydrogeological study that can cost $2,000 before you even scratch the dirt. Check your town’s rules first—or risk a fine that tastes worse than sulfur water.
