Dewatering Techniques

Dewatering involves groundwater by planting, to groundwater levels in the vicinity of the excavation.

The simplest form of dewatering is sump pumping, in which groundwater is permitted to join the excavation where it is collected into a sump and pumped away by solids . Seepage into the excavation can create the danger of instability and other construction problems, although sump pumping could be effective in many circumstances.

To stop groundwater seepage and to ensure stability of base and excavation side slopes it may be required to reduce groundwater levels. This is known as'pre-drainage'.

Pre-waste techniques include:

  • Profound wells/Deep wells
  • Well points
  • Eductors
  • Vacuum wells
  • Flat wells

Other master dewatering procedures are additionally in some cases utilized:

  • Relief wells
  • Artificial recharge
  • Siphon drains

The determination of the dewatering procedure or methods at a specific site or nation will rely upon numerous variables. Groundwater Building's group has many years of involvement in dewatering ventures the world over, and we give an entire structure and establishment administration to control your groundwater issues.
