Construction Dewatering
Installation
Insitu provides engineering support and installs:
- Educator Wells
- - to dewater below 6 m depth in fine sands
- Vacuum Wellpoints
- - to dewater to depths of 6 meters
- Deep Wells
- - to dewater in high permeability soils
Wells can be installed by several techniques using Insitu’s custom-designed equipment:
Jetting
Predilling
Auger drilling
Vacuum Wellpoint System
- Flexible
- Effective in a range of soil types
- Maximum lift 6 m at header line
- Diesel or electric pumps
Vacuum Wellpoint System
Eductor Well System
- Not limited by depth, best in low-yielding wells
- Energy intensive
- Venturi in base of well creates vacuum
- Effective to greater depths
Eductor Well System
Deep Well / Electric Submersible System
- Most efficient production in high-yielding conditions
- Effective in deep coarse aquifers
- Least impact on surface traffic
