Deep Well Systems

Deep Wells: For Large Water Volumes 

Deep Well systems are used when large volumes of groundwater must be pumped, highly permeable soils result in rapid recharging of the aquifer, and/or the depth of excavation excludes other dewatering methods.

The Deep Well System is also a versatile predrainage dewatering system which can pump high and low volumes of groundwater. This method is best suited to homogeneous aquifers that extend well below the bottom of the excavation. Deep well systems consist of one or more individual wells, each of which has its own submersible pump at the bottom of the well. Deep well systems are suitable for water-table or confined aquifers and will lower the water table 100 feet or more in a single lift without staging.
