How to Plan a Dewatering Project - Checklist

Developing an efficient dewatering management plan is the first step in a successful dewatering project. Utilize our project checklist to ensure you don’t miss a step when gathering important information and planning dewatering activities.

Collect Project Information

dewatering project information
  • Type of project (utility, commercial, infrastructure)
  • Excavation size, depth, type
  • Shoring Method
  • May be limited on discharge capacity

Understand Site Hydrogeology & Flow Rate

Groundwater modeling
  • Boring logs
  • Lab analysis (soil grain size)
  • Geologic setting
  • Pump/slug test data
  • Groundwater modeling
  • Analytical calculations

Groundwater Discharge Considerations

dewatering discharge consideration
  • What contaminants are in the water?
  • How much water will be discharged
  • Where will water be discharged?
  • Discharge permitting needs

Dewatering System Selection & Installation - Project Factors

Dewatering system layout drawing
  • Geologic conditions
  • Subsurface water table
  • Depth of excavation
  • Amount of drawdown
  • Required pumping rate
  • Installation technique: bucket auger, jetting, sonic
