DAM & LEVEE GROUNDWATER CONTROL

As our national dam and levee infrastructure ages, the pressure to stabilize construction sites and lower costs continue to rise. There is high demand for stability & performance for projects with complex geotechnical conditions like dams & levees.

EDUCTOR SYSTEMS FOR
COMPLEX DAM REHABILITATION

Griffin’s eductor systems are a safe, cost-effective dewatering solution for high-risk and geotechnically complex projects.

  • Eductor systems lower groundwater tables
  • Create stable working conditions
eductor system

EDUCTOR SYSTEM DESIGN

  • Series of wells are drilled and connected to common header
  • High-pressure water is pumped to the eductor at the bottom of the well, creating a vacuum that removes groundwater
  • Systems perform in depths greater than 20 ft.
  • Depressurizes surrounding impermeable soil formations such as clays & silts

EDUCTOR SYSTEM CAPABILITIES

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