Products - Wellpointing

The wellpoint system is one of the most versatile of dewatering methods.  It involves installing or jetting a series of closely placed small wells (wellpoints) spaced along a trench or around an excavation site, all connected to a common header that surrounds the excavation and attached to one or more wellpoint pumps.

This system is very effective in a wide range of soils from fine silted sand to coarse gravels, and is most suitably implemented for relatively shallow excavations up to approximately 6 metres deep in stratified soils. Due to the vacuum limitation of the pump, excavations that are deeper will require multiple stages of wellpoint systems.

At Carrier Rental Systems , we understand requirements may sometimes vary drastically from one job to another. Whatever your job requirements, we have the equipment available to meet your needs.

** All equipment can be combined to provide the necessary flow capacity requirements.

Factors that must be put into considerations when designing a wellpoint system are:

  • The physical layout
  • Adjacent areas
  • Soil conditions
  • Permeability
  • The amount of water to be pumped
  • Depth to imperviousness
  • Stratification
  • Friction losses developed in the suction side system
