Ideal for shallow aquifers where the water level needs to be lowered no more than 15 or 20 feet, Griffin well point systems allow you to pump anything from a few gallons per minute in fine sandy silts to thousands of gallons per minute in coarse sands and gravels. Our most versatile pre-drainage solution.
This system features well points spaced around an excavation and connected to a common header, which is in turn attached to one or more pumps. Deeper excavations will require multiple stages of well point systems due to the vacuum limitation of the pump.
