Dewatering processes are important for construction sites. Dewatering techniques in construction allow the construction of the foundation in dry conditions. Due to dewatering, groundwater control changes, and properties such as land physical change get formed.
The well-point system consists of more than one point known as well to dewater water from the trench. All such wells are connected to the common header pipe. This header pump sucks the water out of the pipe.
Generally, there are various water techniques to control the most common and complex problems like groundwater. If dewatering is ignored during project planning of a construction project then it can lead to project delays and overrunning costs. Thus, dewatering is very important in construction projects.
What is Dewatering?
Dewatering is a process of the removal of groundwater intentionally from a specific location. Dewatering is the process of removing surface water or groundwater from the construction site or any other site by pumping. In construction sites, dewatering is required because it creates dry and stable soil for construction site preparation, and foundation excavation is done by temporarily lowering the surrounding water table.
What is a Well Point Dewatering System?
A well-point pump is nothing but two separate pumps combined that pump water out of a header pipe. The well-point system consists of a vacuum pump to remove air. Air control plays a vital role in a well-point system because if there is excess air in the header pump then it will reduce the efficiency and performance of the pump.
The dewatering pumps used in the well-point system are specially designed for the dewatering function and they are available in sizes of 4” to 10” of different capacities.
A well-point dewatering system is used for a construction site working in stable working conditions. A well-point system is used for various purposes, including trench work, shallow foundation, and dewatering utility.
Benefits of Dewatering Construction Site or Advantages of using a Well Point Dewatering System in Construction Projects
As we have seen above, unattended dewatering of a construction project can lead to project delays and overrunning costs. Therefore, in construction projects, dewatering is very much essential.
Some of the benefits of Well-Point Dewatering include:-
- Worker Safety :
With the help of the dewatering process, employees become happy, healthy, and most importantly safe. However, standing water is often contaminated and thus it causes various health risks for crews, site managers, their families, and also for surrounding communities. It also increases the risks of worksite injuries due to slips and falls. All this can be avoided with the help of a well-point dewatering system
- Stable Soil and Stable Work Area :
The dewatering process removes the excess water carefully and safely. Thus, it prevents dangerous and harmful hazards like unstable foundations, mudslides, and equipment failure due to bogging. The process of dewatering makes sure that your worksite is in a condition ready for excavation, then it is ready for foundation preparation, and then for cement footing pours. The dewatering process controls the hazards, which in turn almost guarantees a stable work environment for site managers and crews.
- Protect Valuable Equipment:
We all know that construction equipment and building materials are very expensive. Standing water can produce excess moisture. This excess moisture can impact your equipment’s integrity and destroy materials essential for keeping your worksite on schedule. To avoid these project delays you can employ preventative dewatering measures to keep your worksite and storage warehouse free from excess water.
- Scheduling :
When you incorporate an effective dewatering strategy it helps you to keep your construction project on schedule. There can be many adversities during any stage of construction such as flooding from continuous rain and unexpected storms. But effective well-point dewatering techniques can decrease such unnecessary delays.
Less Impact on the Surrounding Environment :
When you incorporate an effective dewatering strategy it helps you to keep your construction project on schedule. There can be many adversities during any stage of construction such as flooding from continuous rain and unexpected storms. But effective well-point dewatering techniques can decrease such unnecessary delays.
Amongst all the other methods, the well-point dewatering method is the most effective method of dewatering for the construction site. Even if you are not well versed in this method, you don’t have to worry as many providers specialize in this.
Wellpoint dewatering is one of the most cost-effective methods of dewatering. It consists of several small wells drilled into the ground to a specific depth and spaced appropriately around the excavation. These wells are connected to the surface and to a header pump to deplete the water below the surface.
This method is also capable of removing a significant amount of solids. It is appropriate for shallow depths to 6 meters, and thus it is suitable for most sites.
However, multi-story projects may need to employ other dewatering methods as per their requirements.
