Ejector Systems

Ejector dewatering system at the London Olympic Aquatic CentreEjector dewatering systems can dramatically improve ground conditions up to depths of 50m. WJ is the industry leader in the design, installation and maintenance of ejector systems, having installed then on some of the UK’s largest infrastructure projects in recent decades including the Conway Crossing, Crossrail, and the installation of new drainage along the M3.

Pictured right is our ejector dewatering system rigged for the Olympic Aquatic Centre, London.

Ejector pumping stations, located centrally, feed high-pressure water to the base of the wells via an ejector body. The flow of water through the nozzle generates suction in the well, drawing in groundwater.
