What is Dredging?

Dredging is used when you need to remove or move sediment from resources. Sediment is material deposited by water, wind, or glacier or is already existing on the bottom of a water body. This is why sediment can be found in numerous places such as streams, lakes, coastal waters, the earth, and more. With all the different places that sediment can be found, there are different classifications of dredging.

What is Dredging Used For?

Dredging is used for a number of reasons such as:

  • Environmental Dredging- This type of dredging is used to clean contaminated areas and restore the area to non-contaminated levels.
  • Construction Dredging- This is used during construction projects to help remove land, create land, create channels, or other various construction needs.
  • Restoration Dredging- Dredges are used to restore coastlines, wetlands, lakes, streams, and beaches by pumping materials ashore to create new land or restore eroded material.
  • Navigational Dredging- Dredges can be used to widen or deepen waterways and channels to help improve navigation.
  • Mining Dredging- Dredging can be an effective way to excavate for precious metals, coal, phosphates, and other minerals that are mined.
  • and more

At Handex we are experts in Environmental Dredging, we have over 50 years of experience in cleaning up contaminated areas in numerous industries to ensure everything is running efficiently. We can help you find the best dredge type for your project and ensure your project runs smoothly and meets regulations.

Dredge Types

There are two primary types of dredges:

  • Hydraulic dredges move sediments by slurry and pumps.
  • Mechanical dredges move sediments by picking them up.

At Handex we regularly use hydraulic dredges to clean up lagoons, pits, and ponds to ensure they are running at optimal efficiency.

How Lagoon Dredging Works

A dredge is used to remove sludge and sediment from the bottom of a lagoon. Dredges are equipped with a submersible pump that uses suction to suck up debris from the lagoon. In order to loosen up debris, a dredge uses a rotating cutter-bar. That loosens debris is then suctioned up from the bottom of the lagoon to the surface. Once it reaches the surface the debris is transported away for final processing.

Why Dredge your Lagoon?

It is important to dredge your lagoon as over time sludge and sediment accumulate at the bottom, which causes unpleasant odors and appearance. Lagoons also need regular maintenance as the added sludge or sediment can cause the lagoon to exceed its original capacity. The main benefits of dredging your lagoon are:

  • Eliminate sludge, sediment, and odor
  • Improve the appearance of the lagoon
  • Restore and maintain original capacity
  • Ensure optimal efficiency
