How deep is a well for water?

Most household water wells range from 100 to 800 feet deep, but a few are over 1,000 feet deep. Well yields can be increased by fracturing the bedrock immediately around the drill hole and intercepted rock faults.

How deep does a well have to be dug?

Since it is so difficult to dig beneath the ground water table, dug wells are not very deep. Typically, they are only 10 to 30 feet deep.

What is considered a deep water well?

If you don’t have a water source close to the surface or your property sits on rocky geography, you may have to look into deep wells. These wells tap into a water table deep underground, as far down as 1000 feet. Deep wells have higher protections against potential surface contaminants.

Do deeper wells mean better water?

In general, when it comes to water quality and well depth, there’s one golden rule: the deeper the well, the better the water quality. As you go deeper down, there’s a higher chance that the water you encounter will be rich in minerals.

How far can a pump push water vertically?

Typically, atmospheric pressure limits vertical suction lift of pumps to 25 feet at sea level (see chart below). This does not mean that you are limited to 25 feet of pipe, you could use upwards of 200 feet of suction pipe, so long as the liquid source is not lower than 25 feet below the pump center line.
