Dewatering and water management are essential aspects of many construction or quarry operations. SP International Services(SP co) takes a planned and integrated approach towards water management, incorporating the overall construction development strategy, operational requirements, and environmental considerations.
Common Groundwater Control Techniques by Pumping
- Sump Pumping: A basic and widely-used method where water is collected in a sump and pumped out.
- Wellpoints: A more advanced method using a series of small-diameter wells to lower the water table.
- Deep Wells: Suitable for deeper excavations, where deep wells are drilled and equipped with submersible pumps.
Less Common Dewatering Techniques
- Eductor Wells: Uses a venturi effect to draw groundwater out, ideal for low-permeability soils.
- Electro-osmosis: Employs electrical currents to move water, often used in fine-grained soils.
- Horizontal Wellpoints and Relief Wells: Specialized systems for controlling water flow in challenging conditions.
