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.Systems are designed to pump large amounts of groundwater, which creates a broad cone of influence. To umožňuje umiestnenie vrtov na relatívne široké centrá a vyžaduje, aby boli vŕtané oveľa hlbšie ako WellPoints.
