10-Inch Subdredge – Remote Operated Submersible Dredge
Industries Served
Mining
The 10-Inch Subdredge is widely used in mine tailings ponds, slurry transport, and mineral recovery. Its ability to pump 40–70% solids by volume makes it efficient for handling abrasive mixtures such as iron ore fines, copper tailings, and coal slurry. The liner-safe rubber tracks prevent damage to protective pond liners, reducing environmental risks while maximizing reclamation efficiency.
Municipal & Industrial Lagoons
Municipalities and industrial facilities frequently encounter challenges related to sludge accumulation in wastewater treatment ponds and lagoons. Traditional methods are slow, labor-intensive, and risk damaging liners. The Subdredge offers remote, unmanned dredging, minimizing downtime and reducing operational costs. With real-time sensors and camera guidance, operators can achieve precision desludging while minimizing risks to worker safety.
Sand & Aggregate
Sand and aggregate producers rely on continuous removal of abrasive mixtures to maintain production levels. The Subdredge excels in harsh sand mining environments, efficiently handling large solids up to 9 inches in diameter. Its non-clog head ensures minimal downtime, while production rates of up to 350 cubic yards per hour keep operations on schedule.
Energy
Coal-fired power plants and other energy facilities must regularly remove fly ash and bottom ash from ponds and containment areas. The 10-Inch Subdredge offers a safer and more efficient alternative to mechanical excavation. With its remote operation capability, the unit minimizes human exposure to hazardous waste while ensuring high-volume ash removal for compliance and plant safety.
Marine Construction
For projects involving ports, docks, shipyards, and offshore platforms, the Subdredge allows operators to dredge beneath structures or ships where conventional dredges cannot access. Its remote-operated design and precision control enable targeted removal of sediments in restricted marine environments, making it invaluable for infrastructure maintenance and construction support.
Infrastructure
The Subdredge supports dam maintenance, canal dredging, and lined reservoir cleaning, where precision and liner safety are critical. Its rubber track mobility allows it to operate on lined surfaces without tearing or puncturing, ensuring regulatory compliance while extending the lifespan of critical water infrastructure.
Environmental Remediation
Contaminated waterways and industrial ponds often contain hazardous materials that cannot be handled with conventional dredging equipment. The Subdredge provides a controlled, unmanned solution that removes pollutants while reducing risk to workers. Its ability to transport high solid concentrations means fewer passes and lower project costs during cleanup operations.
Ports & Harbors
Sediment buildup in ports and harbors reduces draft depth, hindering shipping operations. The Subdredge delivers efficient maintenance dredging in restricted, deep, or hazardous locations, ensuring navigation channels remain clear. Its remote operation and high productivity make it well-suited for continuous port maintenance programs.
Case Study
Challenge
A major coal-fired power plant in the United States experienced a significant accumulation of fly ash and bottom ash in its containment pond. The pond’s storage capacity was reaching critical limits, creating both environmental and regulatory concerns. The EPA had issued compliance deadlines for ash pond remediation, requiring the safe and efficient removal of ash without damaging the pond liners. Traditional methods, such as mechanical excavation and diver-assisted dredging, posed several risks:
- High turbidity levels lead to water quality violations.
- Worker safety hazards from exposure to contaminated materials.
- Slow progress due to equipment limitations in handling dense, compacted ash.
The plant required a dredging solution that was fast, safe, liner-friendly, and compliant with strict environmental standards.
Solution
The power plant deployed the EDDY Pump 10-Inch Subdredge, a remote-operated submersible dredge (ROV) engineered for high-solids pumping and liner-safe operation. Key deployment steps included:
- Remote Operation: Operators controlled the Subdredge from the shoreline, eliminating the need for divers or direct human exposure.
- Cutterhead Attachment: Enabled the dredge to break through compacted fly ash deposits while maintaining flow efficiency.
- Real-Time Monitoring: Integrated turbidity sensors, pressure sensors, and dual low-light cameras provided continuous feedback, ensuring precise dredging within regulatory limits.
- High Solids Handling: The Subdredge pumped 300–350 cubic yards per hour with a solids concentration of up to 70% by volume, minimizing the number of passes needed.
Result
The 10-Inch Subdredge delivered exceptional outcomes for the coal power plant:
- Regulatory Compliance: All EPA requirements for fly ash pond remediation were met, with the project completed two months ahead of schedule.
- Cost & Manpower Savings: Remote operation reduced labor needs by 40% and eliminated diver-related risks, lowering overall project costs.
- Environmental Protection: Real-time turbidity monitoring ensured minimal environmental impact during the dredging process.
- Operational Efficiency: The plant successfully restored pond capacity, reducing the risk of overflow and enabling continued operations without costly shutdowns.
This project demonstrated the 10-Inch Subdredge’s ability to handle hazardous ash ponds more safely, efficiently, and economically than conventional dredging methods.

Frequently Asked Questions
What makes the 10-Inch Subdredge different from conventional dredges?
The Subdredge is a remote-operated vehicle (ROV) designed for unmanned operation in hazardous or confined environments. Unlike traditional dredges, it eliminates the need for onboard operators, improves safety, and can access areas beneath structures, in lined ponds, or in deepwater conditions where other dredges cannot operate.
Can the Subdredge operate on lined ponds without causing damage?
Yes. The Subdredge uses rubber tracks that are engineered to protect clay, poly, and concrete liners. This makes it an ideal solution for tailings ponds, wastewater lagoons, and other lined environments where preventing liner puncture is critical.
What types of materials can the Subdredge pump?
The 10-Inch Subdredge is capable of handling a wide range of abrasive and viscous materials, including sludge, slurry, mine tailings, fly ash, coal ash, and sand mixtures. It can transport 40–70% solids by volume and solids up to 9 inches in diameter, making it highly versatile.
How much material can it move per hour?
The Subdredge can pump up to 5,000 GPM and transport 300–350 cubic yards of material per hour, depending on material density and site conditions. This makes it one of the most efficient unmanned dredging systems on the market.
What is the maximum dredging depth of the Subdredge?
With its buoy-supported umbilical system, the Subdredge can operate at depths of up to 40 ft. Its remote-controlled design allows operators to maintain precision and productivity even in difficult underwater conditions.
