What is a Wellpoint system?

Wellpoint systems are used to lower groundwater levels to provide stable working conditions in excavations. … A wellpoint system consists of a series of closely spaced small diameter shallow wells. The wellpoints are connected to a common header pipe and are pumped with a high efficiency vacuum dewatering pump.

How does a Wellpoint pump work?

The wellpoint pump creates a partial vacuum in the header main, which draws up the water so that it can be discharged at a designated point. Typically, wellpoints are installed around the perimeter of an excavation, or parallel to a pipeline trench, by either jetting, auguring or traditional drilling techniques.
