  • The Four Major Dewatering Methods and How to Choose One

    The eductor well method is a dewatering process used to control pore water pressures in materials with low permeability characteristics, such as fissured clays or silts. This method uses the venturi principle, where high pressure water is circulated through eductors in the base of each well to create a vacuum that helps promote drainage.

  • The Four Major Dewatering Methods and How to Choose One

    This dewatering method uses rings or lines of closely spaced wells that are installed around the excavation area. The wells, or wellpoints, are then connected to a headerpipe and pumped by wellpoint pumps that can handle both water and air. This system primarily works using the suction principle, so drawdown using this method is limited to around five to six meters below the wellpoint
