How to Drill a Water Well Through Rock


While drilling a water well, my bit hit something solid and nothing seems to work to get past it. Any suggestions? -Jeff

Hi Jeff,

You’re drill bit is probably hitting rock, and while you can drill a water well through rock, it will definitely slow the process way down. Drilling through a big rock can slow drilling down to as little as half an inch per hour!

The real problem isn’t big rocks, however, but rocks about the size of a small melon. On rocks that size, the drill bit doesn’t have anything to bite into, so it just rolls off. While it’s not impossible to go around rocks when drilling a water well, it can be so time consuming that drilling the well in that particular location may not be practical.

You can always try drilling your water well in another location on your property, but there’s no guarantee that the layer of rock you’re hitting doesn’t run under the entire property.

Good luck with your project,
