How do you drill a bedrock water well? A drill bit at the end of a long pipe is rotated into the ground. It crushes the rock as it goes until the right depth is reached. A water and mud slurry is pumped down through the drill bit to clear the crushed rock out of the well.

How do well drillers know where to drill?
Geophysics methods can be used to identify the presence of water at depth. They are based on the changes in electric conductivity caused by the water. Finally bore holes can be drilled to assess the geological sequence of the strata and to identify layers potentially able to host an aquifer.
How deep should a well be for drinking water?
100 feet deep
For drinking water wells it’s best to be at least 100 feet deep so that surface contaminants cannot enter the well. The average well depth for private homes is between 100 to 800 feet [2]. You may need a deeper or shallower well if your area has different geology than another region of the country.

What type of foundation is suitable for hard rock?

When the soil is rocky with high bearing capacity, then shallow foundation of strap footing is good and work well.
Can you excavate bedrock?

That’s a no-brainer, and I’d question the judgment of any contractor who would suggest putting compacted fill on top of bedrock, then building a foundation on that. That’s a waste of materials and it’s not as reliable an approach.
