Dewatering
Dewatering or dry suction lower the groundwater level to enable earthwork to be carried out in dry conditions, e.g. for construction pits, sewers and utility lines. This can be achieved through various techniques: filter dewatering, deep wells, return dewatering, horizontal drains and vanes. Applications are permanent dewatering, groundwater purification plants and pump tests.
