Each type of dewatering system has its advantages and limitations. The selection of the best solution for your project requires the review and evaluation of many factors including the size of the excavation, anticipated flow rates, permeability of the soil and substantially dry conditions.

Wellpoint systems are a series of wells connected to a common manifold and activated by a continuously primed pump. Vacuum wellpoints are highly effective when excavations extend to depth of up to 5-m below ground surface and work well in both high and low permeable soils. Vacuum wellpoint pumps come in both electrical, diesel and sound attenuated diesel configurations. Wellpoints are quick to install and easy to adapt to specific site conditions.

Eductors are a vacuum-based system where the vacuum is generated in the well with a venturi. Eductors are highly effective in stratified or low permeable soils. Eductors are not limited by the depth.

Deep wells use submersible pumps suitable for pumping large volumes of water. Deep wells are independently operated and are not limited by depth. Pumps are electrically operated. Vacuum can be introduced into a deep well system to aid in well performance.

Groundwater control for construction projects is an essential part of the success of the project. Water entering an excavation can cause slope or basal instability. Dewatering of the site can keep projects on schedule, keep working conditions stable and provide workers safety working in dry conditions.
