If the Electrical Submersible Pumping System Size of a Water Well is Increased, Will the Supply of Underground Water increase?

Increasing the size of the pump to improve the water supply could be an alternative, but it is essential that the pump should not exceed the maximum safe pumping capacity of the well or the specific head at which the pump must raise the water.
If the pump is the correct size, and operating properly, replacing it with one that is too large may cause severe damage to the well. This is particularly true in small diameter drilled and completed wells.
Putting a pump with increased pumping capacity into a large diameter dug or drilled well will not provide more water. It will only provide the same amount of water at a faster rate, and your water supply will remain unchanged.
