Dam and Levee Groundwater Control


High-pressure, high-stability eductor systems for complex rehabilitation.

As our national dam and levee infrastructure ages, the pressure to stabilize construction sites and lower costs continue to rise. Griffin eductor systems provide a safer, more cost-effective dewatering solution for these geotechnically complex, high-risk projects.

Griffin’s eductor systems lower groundwater tables and create stable working conditions. A series of wells are drilled and connected to a common header. High-pressure water is pumped to the eductor device at the bottom of the well, creating a vacuum that lifts the standing water.

As high-pressure water is pumped into the wells, groundwater is removed. Our eductor systems perform in depths greater than 20 feet, where common wellpoint systems cannot. They can also successfully depressurize surrounding impermeable soil formations such as clays and silts.

• More versatile than wellpoint systems
• Lower the water table as much as 90+ feet
• Higher performance in stratified and/or low permeability soils
• Greater stability in fine grained soils
• Low maintenance
