Dewatering is an essential component of any large-scale construction project, the purpose of which is to dry out and stabilise ground to allow for safe excavation and construction work. Without dewatering – in cases where it is required – there would be a substantial risk of ground instability, resulting in the failure of any future construction.
There are a number of factors that need to be considered when carrying out dewatering for construction sites:
- The level to which the water table is to be reduced
- Geology and typography of land
- Construction layout
- The volume of water to be removed.
