Groundwater Control and Dewatering Methods

Understand the basics of dewatering design, potential pitfalls relating to dewatering, and several options for how to specify dewatering systems.

Groundwater control on construction projects is often misunderstood. The techniques involved in dewatering are generally not taught at the undergraduate level in civil engineering programs and the entire process is often relegated to 'Contractor Means and Methods' without consideration of important details. This presentation will give attendees the basics regarding advantages and disadvantages of common dewatering techniques and an understanding of the information dewatering designers consider when designing a system.

Learning Objectives

  • You will be able to discuss various methods of specifying dewatering.
  • You will be able to explain how the three major dewatering techniques work and their pros and cons.
  • You will be able to identify potential pitfalls and hazards of dewatering.
  • You will be able to review a dewatering proposal and assess its appropriateness for a given project.
