DEWATERING SYSTEM

What is dewatering?
Dewatering is the process of removing surface or groundwater from a particular location. It can also be known as the process of draining rainwater or groundwater. Every construction site's technique for dewatering will be different from others.

Methods of dewatering?
Construction dewatering system methods refer to unique techniques such as well points, deep wells, bypass, flood control, etc. Everyone has a different procedure for dewatering. Here are the different methods of dewatering which is as follows.

Wellpoint
Deepwells
Bypass Dewatering
Flood control
Tunneling Dewatering

Wellpoint
In wellpoint dewatering, the well will be drilled around the excavation area with submersible pumps installed in the good shaft. These pumps are connected to a header pipe allowing the groundwater to be drawn up by the pumps into the Wellpoint and then discharged. There are three types of well-point systems:

Single-stage system
Multiple-stage system
Vacuum System

Deepwells
In deep well dewatering system ...
... it consists of bored wells in series fitted with submersible pumps at the bottom. Each well will be capable of creating a cone of depression around itself while drawing water to the surface.

Bypass Dewatering
When sewer lines need maintenance, the sewage flow is pumped around the damaged pipe section using dewatering water pumps. The pumps are installed upstream of the maintained pipe section. The bypass technique is also common in irrigation and construction projects.

Flood Control
Flood control refers to all methods used to reduce or prevent the harmful effects of flooding.

Tunneling Dewatering
Tunnel constructions are complex worksites where many variables should be considered first. Significant volumes of water from the construction site need to be removed to stabilize the ground or prevent flooding of the work area.

Necessity of dewatering:
Dewatering is the safety of the structure around the pit in the following conditions:
Ease of concreting or masonry in the foundation
To protect concrete
To prevent soil erosion
Deep excavation
Construction in a water-logged area
Docks
Pile Foundation

Tips of Dewatering System:
Choose the proper discharge area
Check the signs of instability or erosion in the area during dewatering system
Shouldn't pump water directly into slopes
Channels used for dewatering system must be safe
Avoid dewatering under heavy rain
Water contamination with any chemical products must be solved before starting the project
Don't discharge contaminated water
Enquire about the permit details and requirements for dewatering
Analyze the conditions of water in the project area

CONCLUSION:
Selecting a dewatering method will be based on soil conditions and the water stability.
