Technical background
Site De-watering is commonly required when excavations are required to be deeper than the natural water table.
For shallow excavations (generally under 4 meters) well-point De-watering is commonly adopted achieve an adequate draw down in permeable soils. (i.e. sand, clayey sand etc.)
Deep well De-watering is recognized as a cost effective and efficient way for medium to long term De-watering of larger projects where the excavation is greater than 4 meters or when a well point system is deemed inefficient.
Our system has many advantages:

Our system has many advantages:
- Minimal noise
- Easy to install
- Does not rely on vacuum inducement that is typically associated with spear point (well point) De-watering systems.
- Relatively maintenance free as the submersible pump sets are housed in the deep well and cooled by the flowing groundwater.
