Considering that the pump is usually at the end of the deep well, there are no elevation restrictions as a result of vacuum lift, and also deep wells can lower the groundwater over 50 feet.

On the bottom of the wellpoint there is a 2 foot long screen as well as shutoff, water jets out of this shutoff and also develops an opening right into which the wellpoint pipeline can be decreased. This hole is typically made a bigger size (for instance 10 inches) to permit a coarse sand backfill to help filter the water (mini excavator).
