Wellpoint dewatering can be used to lower and control groundwater levels in excavations, in order to create a dry and stable working environment. Some of the suitable applications are pipeline construction, shallow foundations and trench works.
A typical wellpoint dewatering system will consist of a number of wellpoints which are installed at an effective depth and appropriate spacing around or parallel with the excavation. These wellpoints are installed into the ground using a high pressure jetting technique, by hand . The wellpoints are connected to the surface, via a riser pipe, and in turn, connected to a common header main pipe. The main header pipe is connected to a wellpoint dewatering pump and then discharged via a settling chamber to a designated/approved discharge location.
