Wellpoint System

Well Points: The Versatile Solution

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.

When designing a well point system, Griffin will take into consideration a variety of factors, including:

• Physical layout
• Adjacent areas
• Soil conditions
• Permeability
• Amount of water to be pumped
• Depth to imperviousness
• Stratification
• Friction losses developed in the suction side system
