Because the pump is normally at the end of the deep well, there are no height limitations due to vacuum lift, as well as deep wells can reduce the groundwater over 50 feet.

On the base of the wellpoint there is a 2 foot long screen and also valve, water jets out of this valve and also develops an opening into which the wellpoint pipe can be reduced. This opening is often made a larger diameter (as an example 10 inches) to enable for a crude sand backfill to help filter the water (trencher).
