Wellpoint Dewatering System
Well point system is one of the most versatile and pre-drainage methods which can pump a few gallons per minuet in fine sandy silts or many thousands of gallons per minute in coarse sands and gravels. A well point system consists of a number of well points spaced along a trench or around an excavation site, all connected to common header pipe, which is attached to one or better point dewatering pumps.
Well point system is more suitable in shallow aqui...
Well point system is more suitable in shallow aquifers where water level needs to be lowered no more than 15-20 feet. Due to the vacuum limitation of the pump, excavations that are deeper will require multiple stages of well point systems.
