Wellpoint systems and dewatering
Wellpoints - application and functional idea
Wellpoint systems are broadly used and recognized in the construction of drainage systems for building trenches/excavations.
Wellpoint systems are designed for draining fine-grained soils, which do not give water easily. Their characteristic feature is a system of densely spaced inlets with small cross-sections, connected in paralell via a suction header pipe with a pumping engine.

Main applications of wellpoint systems
Example applications:
-
Dewatering water from a ground when excavations below ground water level are needed
-
Dewatering construction excavations
-
Lowering of ground water level
Other applications of wellpoint system:
-
Dewatering in agriculture
-
To gain water for house, garden and irrigations

Jetting wellpoints into the ground
The typical sequence of operations when installing wellpoints is as follows:
- connect jetting pipe to water jetting pump or
hydrant, using jetting hose
- if you are setting the wellpoint manually, position the jetting pipe vertically with
its edge on a support (e.g. piece of thick board), next to the predetermined
wellpoint setting location
- when you set the wellpoint with jetting pipe using a crane, keep the pipe on the
crane rope 150-200 mm above the wellpoint setting location
- activate water jetting pump or open the hydrant
- when water flows out of the jetting pipe, remove it from the support and lower it
to the ground
