Deepwell Systems

Deepwell dewatering system

A deep well system consists of an array of bored wells, each fitted with a multi-stage electric submersible borehole pump. As water is pumped from each well, the groundwater is lowered creating a cone of depression or drawdown around itself.

Why Use Deep Well Systems?

Deepwell dewatering is suited to deep excavations and where soil permeability is moderate to high. Deepwell systems also work well where artesian groundwater pressures threaten base stability. Capable of pumping tens of thousands of gallons of water per minute, deepwell systems are effective when there are large volumes of groundwater. The flexibility on the well depth and the well spacing means access restrictions are kept to a minimum.
