Deep well dewatering systems lower groundwater using a series of drilled wells, each fitted with an electric submersible pump. Deep well systems are often used to remove water from pervious formations that extend well below the excavation.
This solution is ideal when it is necessary to pump large amounts of groundwater or when significant drawdowns are required.
Deep well systems are a gravity drainage system, typically consisting of widely spaced wells. Systems are designed to pump large amounts of groundwater, which creates a broad cone of influence. This allows wells to be placed on relatively wide centers and requires that they be drilled much deeper than wellpoints.
