WELLPOINT SYSTEMS

Wellpoint Dewatering is a simple, efficient method of temporarily lowering the groundwater table in a localized area to accomplish the construction of a foundation, pipeline or any other below-ground structure. The system consists of a series of small wells called wellpoints installed around the excavation and connected to a manifold or "header pipe" which is connected to a wellpoint pump. This wellpoint pump is designed to handle the water as well as entrained gasses found in the water. The entire system affects only the area of the construction site and has minimal effect on water quality.

Pictured here is a wellpoint system installed about 15' down inside an excavation to lower the groundwater in a troublesome site where conventional deep-well dewatering was unable to completely dry the footing, due to low-permeability layering of the soils.
