We use the Well Point System which is an advanced system that is far superior to the old steel system. It is highly efficient and has a successful track record as the most satisfactory method of eliminating problem of sub-surface water from construction sites besides lowering the on-site water table to a grade below the level of proposed excavation.
The Well Point System offers a wide range of pumps to cater to different applications in standard sizes of 4" (110 mm) through 10" (250 mm) suction. Custom-built pumps are available on order. They are designed for discharges ranging from 30 to 200 Lt/sec. All of them come with either a diesel engine or electrical motor drive with skid mounting or wheeled trailer chassis as needed. Standard units come with a high capacity vacuum system which can be used with either oil lubricated oil cooled or water lubricated water cooled. The vacuum pumps can pump 1.5 to 2.0 mm of free air.
Well Point system consists of a number of Well Points spaced along a trench or around an excavation site, all connected to a common header, which is attached to one or more Well Point pumps.
Well Point systems are most suitable in shallow aquifers where the water level needs to be lowered not more than 15 or 20 feet. Due to the vacuum limitation of the pump, excavations that are deeper will require multiple stages of Well Point systems.
