  • Lagoons
  • Ash slurry ponds
  • Water treatment facilities
  • Channels and canals

Benefits of Hydraulic Dredging

Hydraulic dredging is one of the most efficient forms of removal and transport of dredged sediment and debris, and because all material is contained within a sealed pipeline, there is minimal impact to the surrounding community and infrastructure. When combined with a proper debris management program, hydraulic dredging is one of the most economical and effective approaches for challenging dredge conditions.

Hydraulic Dredging Considerations

When considering a hydraulic dredging option, one should not assume that the presence of heavy debris will be an impediment to production.  Coupled with an aggressive debris management program, hydraulic dredging can be every bit as effective as a mechanical dredge plan.  At Brennan, we often implement a hybrid dredge plan that incorporates both surgical hydraulic dredging and mechanical dredging. This approach will maximize production while ensuring that any dredge residuals are minimized/ eliminated.  

In addition to our dredging capabilities, a complete environmental remediation and restoration often involves the installation of a barrier wall system and turbidty controls. When dredging is completed, the river bottom or lakebed is often covered with sand or an engineered cap to create a clean substrate for re-population of the benthic community.  

Hydraulic Dredging vs Mechanical Dredging

Brennan also offers mechanical dredging services using state-of-the-art positioning equipment to maximize production and preserve accuracy. You can learn more here.

Hydraulic Dredging Cost

Dredging projects are complex affairs that involve many components and significant planning before execution. The intricacy of these projects means that pricing is often multifaceted. Here are seven common areas that drive overall costs on a dredging project.

  1. Engineering & Permitting Costs
  2. Mobilization Costs
  3. Depth & Type of Sediment
  4. Allowable Run-Times
  5. Transport Distance
  6. Disposal
  7. Water Management
