The first consideration is the distance water needs to travel to reach the surface. If your area has a stable supply of water near the surface, or a high water table, it will be much easier to access water for your home. Deep wells, on the other hand, require additional considerations.
Depth Considerations – Depending on Where Well Pumps Are Located
If less than 25’, use a shallow well jet pump
If 25’ – 110’, use a deep well jet pump
If 25’ – 400’, use a 4” submersible pump
To find out the depth of your well, check the well driller’s well report. If there’s no such report, you can determine water depth by tying a fishing bobber to the end piece of a string and lowering it until you feel the bobber floating. Take up the slack and mark the string.
