What is Dewatering?
Dewatering, also known as unwatering or water control, is a method of removal of groundwater or surface water from a riverbed, construction site, caisson, or mineshaft, by pumping or by evaporation.
What is the process of execution?
- A trencher installs an un-perforated pipe followed by a synthetic or organic wrapped perforated pipe.
- The drain length is determined by the drain diameter, soil conditions and the water table. After installation of the drainpipe, a pump is connected to the drain. After the water level has been lowered, the intended construction can start.
How is Dewatering used?
Dewatering is a necessary aspect of many underground construction projects. Construction sites near coastlines, rivers, dams and other bodies of water and in other situations require dewatering every day, to execute their projects.
