SURFACE DEWATERING

Surface dewatering system enable one to lower the groundwater table adequately in cohesive and low permeable soils. Water is pumped off directly from sumps (ditches) along the toes of the slopes of the excavation works. The suction hose with strainer is merely placed in the sump and the collected water is primed and discharged. This makes the open dewatering system easy to install and simple to operate. The open dewatering system utilizes self priming and vacuum assisted centrifugal pumps.

WHY USE SURFACE DEWATERING

Controlling surface water is also an important part of any excavation. Surface water comes from many sources, including direct seepage from lakes or rivers, leaking water mains and sewers, cleaning of on-site equipment, runoff from concrete installation, or rainfall. Most commonly used for removing surface water are French drains and sump pumps.
