Wellpoint Dewatering

Wellpoint dewatering

Wellpoint systems are used to lower groundwater levels to provide stable working conditions. They consist of a series of small diameter wells that are connected by a header pipe to a wellpoint pump. The pump creates a vacuum in the header pipe drawing water up from the ground.

Welpoints are typically installed along or around an excavation. The height to which water can be drawn by vacuum in this way is approximately 6 metres. To function at greater depths, well points can be installed in stages as the excavation proceeds.

Why Use Wellpoint Systems?

Wellpoint systems are particularly suited to dewatering for shallow foundations and excavations, so they are often used for pipeline trench work. A wellpoint system can be installed quickly in most ground conditions and they are easy to maintain.

WJ Middle East is well equipped to deal with all wellpoint requirements. Our highly qualified team have worked on many projects across the Middle East (as well as the UK and around other parts of the world), including a single-sided wellpoint system at Dubai International Airport.
