When installing a water well outside your home, one of the first questions on your mind is how deep it has to go. It may affect not only the overall cost of the drilling but the quality of the water and the well itself. The exact depth is something that a professional well-drilling contractor is trained to determine, but you can get some idea by becoming familiar with your area and the process of well drilling.

How to Figure Out How Deep the Water Well Must Be

water wellAs a general rule, healthier and more mineral-infused water is found deeper in the ground, so the well should stretch as far beneath the water table as possible. This is the layer of ground just underneath the level where it’s saturated with water. It rises and falls depending on the time of year, so the well needs to go below its lowest expected point, but it’s not easy to figure out its precise distance from the surface. Surrounding rock formations must also be taken into account, as the well will need to hold and store water if the aquifer doesn’t refill quickly. 

To estimate how deep your well will be, a drilling contractor will find out the depth of wells from nearby homes. They’ll also consider the geology of the area and what they know about the aquifer. However, they can’t provide an exact measurement before drilling.

What Happens When the Well Drilling Starts?

A well-drilling contractor makes all the necessary calculations before they start drilling. The water well could end up as deep as 1,000 feet, though most only need to reach between 100 to 500 feet. In any case, the contractor will continue drilling until they find an acceptable water source.
