Dredge Sled – Patented Lagoon Dredging Equipment

The patented Dredge Sled lagoon dredging equipment is highly engineered for submersible dredging with the ability gently slide along the bottom to pump highly viscous or abrasive material, sludge, muck, paste, high solids, and other harsh pond pumping applications.


Efficient Lagoon Dredging Equipment

EDDY Pump is now able to offer a complete dredging solution for effective slurry, sludge, and solids removal, the patented Dredge Sled. With the latest technology, the Dredge Sled is a cost-effective solution for your pond, lagoon, canal, tailings pond, and settling tank cleaning.

The Dredge Sled is powered by the EDDY Pump which is a heavy-duty industrial non-clog slurry pump designed for industrial pumping and dredging applications.

Depending on your project, The EDDY Dredge Sleds are sized to meet our client’s requirements. Powered by the high-performance and low-maintenance EDDY Pump, our dredging equipment usually achieves 30-70% solids and handles high viscosity, high abrasion, and low pH materials without wearing down the pump or constant need for maintenance.

Main Applications: Lagoon Dredging, Dredging Containment Ponds, Settling & Digester Tank Cleaning, Heavy Metal Recovery, Fly Ash, Mine Tailings Transfer

How the Dredge Sled Works

The term slurry is widely used in industrial applications. Slurry widely varies depending on the size of the grain, aggregation, distribution, cohesiveness, pH levels, flow characteristics, sedimentation rates and the specific gravity of the material. The Dredge Sled has been deployed across remote mining sites in Australia for over 15 years to combat mine tailings. This rugged yet simple design uses commonly accessible parts to ensure maximum uptime and easy repairs. The main components include diesel-electric power station, floating barge attached to shore by a cable and winch system. The EDDY Pump is lowered into the lagoon and stabilized with a sled to begin dredging. Optional water jetting rings are available for maximum agitation when desired.

The patented Dredge Sled is a simple, efficient and easy to use alternative to more complicated heavy duty dredging equipment. The best solution for shallow pond or lagoon dredging.

Alternate Deployment Setup With Self-Priming Pump


EDDY pump offers multiple dredge sled pump deployment options, including using a standard submersible EDDY Pump or a Self-Prime Pump Trailer option.

Using a self-priming pump in conjunction with the Dredge Sled offers several advantages:

  • Limits pump corrosion in harsh environments
  • Less weight to float
  • Easier pump serviceability
  • Much safer for ponds with delicate liners

The Dredge Sled excels at removing sediment from bodies of water, lakes or holding ponds. The system is also deployed for desludging settling tanks.  A single Dredge Sled is typically deployed to bodies of water up to 20,000 square meters. In addition, the EDDY Dredge Sleds are engineered and sized to meet the clients’ requirements. Contact us to help with your project.

Applications – Pond & Lagoon Dredging

Mine Tailing Transfer

Mineral tailing ponds generate significant amounts of hazardous solid and liquid mine waste such as: heavy metals, metalloids, radioactive waste, acidic water, and process chemicals. These wastes (tailings) accumulate at the bottom of containment ponds, causing several environmental hazards and reduced water volume.

Containment Pond Maintenance

Containment ponds protect surface water and streams from dirty wastewater. Containment ponds are frequently used for water quality improvement, flood protection, and groundwater recharge. Sediment and sludge accumulate over time on the bottom, limiting water volume and creating environmental hazards. The dredge sled is a cost-efficient solution to desludge your settling tank.

Farm Pond Cleaning

A farm pond is used for irrigation, livestock feed, erosion control, or aquaculture. Over time within livestock farms, dense solid waste accumulates at the bottom while less dense materials float to the top, causing reduced water volume.

Lagoon Dredging

Lagoons are pond-like bodies of water that receive, store, and treat wastewater for a predetermined amount of time. Lagoon dredging is used when sediment buildup is accumulated over time. Neglecting to do lagoon dredging maintenance will cause excess muck and debris to float to the surface, creating a foul odor. When looking for lagoon dredging equipment, the dredge sled is an easy to operate and maneuver allowing you to easily deepen and restore its look and color.

Heavy Metal Recovery

Removing heavy metals within wastewater, such as copper, lead, zinc, silver, and other metals, is a challenge and often regarded as uneconomic. The dredge sled removes these harmful metals through physical agitation while retaining cost efficiency. Use a dredge sled to re-run target materials through your process plant to create an ROI with your Dredge Sled.

Wastewater Management

Proper wastewater management is essential to ensure optimal system functionality. It is vital to maintain proper sediment control and water depths, especially with digester tanks and settling tanks. Sediment buildup will reduce water volume and compromise the integrity of the wastewater system. Dredging is a necessary method to return the lake or pond to a functional and efficient system.
