What are dewatering pumps?:

The process of dewatering involves extracting and removing the water from a construction site, a riverbed, a mine shaft, or any other area. It’s frequently done prior to work beginning in the area. While there are several ways to do this, it usually involves the use of a submersible pump or vertical turbine pump. The process is most useful in areas where the foundation of a building to be constructed is below the water table level.

How do they work?

There are several ways to use dewatering pumps to remove water from an area, but the most common procedure involves digging a deep hole in the area and inserting a round liner with slots around the sides, allowing ground water to seep through. A submersible pump is placed at the bottom of the hole, and when the water rises to a certain level, the pump sends it out.
Some construction projects use a ring of such wells around the construction site. The wells may stay in continuous operation until the foundation of the building is complete and a water removal system such as a sump pump has been installed.
Another method is to insert a series of small, 50-mm tubes down into the ground, and then to have an above-ground dewatering pump draw the water out through the tubes. This may be done in stages, first from the ground level, and again later when the walls of the foundation have placed.

Where are they used?

Construction Dewatering:

Construction dewatering is the process of removing groundwater at a construction site before placing or finalizing a building’s foundation. Water in trenches, excavations, places with inadequate slope, or high water levels should always be removed to provide a safe workplace and environment.

Flood Control :

Flood control is crucial, both to improve and maintain quality of life, and during emergency situations. It is the process of preventing and reducing the possibility of or long-term effects of heavy water movement. Floods can happen via hurricanes, tsunamis, high tide, or severe rainfall from tropical storms.dewatering pumps help to maintain or restore balance no matter the event or situation.

Water Transfer :

Water transfer is a process that diverts water from rivers, oceans, canals, or other bodies of water to an area struggling with little or no water levels.

Bypass Pumping :

Bypass pumping is a temporary solution that operates a sewage treatment system while it is being replaced or repaired. Bypass pumping can be needed when storm water overflows the sewers or when there are leaky pipes, clogged pipes, replacement operations, or for nearby construction projects.

Water Infrastructure Security :

Water Infrastructure Security is the process of securing or protecting a water system, such as a river, canal, lake, aquifer, surface water, drinking water, water tower, or a water tank, from contamination or sabotage. Infrastructure Security deals with protecting important and critical structures in a community, society, or city.
