Well point system
- These are used to lower groundwater levels and help provide safe working conditions during excavation.
- Wellpoint systems consist of a number of small diameter wells, which are connected with a header pipe to a wellpoint pump.
- The wellpoint pump then creates a vacuum that draws water up from the ground.
Additional InformationDehydration
- Dehydration typically refers to the removal of water from substances, and it may not be directly related to lowering the water table. In the context of groundwater control or dewatering, other methods like well points or dewatering systems are more relevant.
Dewatering
- Dewatering is a general term that encompasses various methods used to remove or control groundwater.
- It includes techniques like pumping, well points, sumps, and other drainage systems.
- Dewatering aims to lower the water table temporarily to allow construction or excavation in a dry environment.
Water suction method
- The term "Water Suction Method" is somewhat general, and its effectiveness in lowering the water table depends on the specific techniques and equipment involved.
- Suction methods often involve the use of pumps or vacuum systems to draw water away, similar to the principles used in well-point systems.
