Liner-Safe Dredging Options
Liner-Safe Dredge Options are engineered for sediment removal in clay-, poly-, and concrete-lined ponds without damaging the liner. These systems use non-clog EDDY Pump technology to move high-solids slurry while maintaining precise control at the liner surface. Configurations include sleds, subdredges, excavator attachments, cable-deployed systems, and full-scale barge dredges like the T3. Each solution is designed for low ground pressure, controlled contact, and accurate positioning, allowing operators to restore capacity, improve water quality, and extend liner life in the most sensitive containment environments.
Built for Sensitive Dredging Conditions
- Protects clay, poly, and concrete liners using low ground pressure designs and controlled surface contact, preventing punctures, tears, and premature liner failure
- Uses non-clog EDDY Pump technology to move high-solids slurry directly, eliminating the need for screening, dilution, or frequent shutdowns
- Maintains precise dredging depth so operators can remove sediment without exposing or stressing the liner surface
- Supports multiple configurations, including sleds, subdredges, excavator attachments, cable-deployed units, and full-scale barge dredges to match any site condition
- Enables remote and cable-based operation for confined, hazardous, or restricted-access ponds where personnel entry is limited
- Reduces downtime by avoiding clogging, wrapping, and manual cleanouts common with conventional dredge pumps
- Handles abrasive, viscous, and debris-laden material that defeats centrifugal, vortex, and positive displacement pumps
- Scales from small retention ponds to large industrial containment areas without changing core pump technology
- Removes sediment evenly across the liner surface, preventing high spots, gouging, and uneven wear
- Extends liner life while restoring pond capacity, hydraulic performance, and long-term operational reliability

Liner-Safe Dredging Across Industries
Retention Ponds and Stormwater Basins
Lined retention ponds and stormwater basins accumulate sediment, organic matter, and debris, reducing capacity and hydraulic performance. Liner-Safe Dredge Options allow operators to remove buildup without draining the pond or risking liner damage. Low-ground-pressure designs, controlled contact, and precise positioning enable safe volume restoration while preserving clay, poly, and concrete liners.
Wastewater and Treatment Lagoons
Municipal and industrial treatment lagoons rely on intact liners to protect surrounding soil and groundwater. Liner-safe dredging systems remove biosolids and sludge while maintaining continuous plant operation. Subdredges, sleds, and cable-deployed systems enable targeted removal in confined basins, extending lagoon service life and improving treatment efficiency without disrupting the liner.
Mining Tailings and Process Ponds
Mining operations use lined ponds to contain tailings, slurry, and process water. These environments demand high-solids handling without compromising containment barriers. Liner-Safe Dredge Options scale from compact systems to full barge dredges, allowing safe removal of dense, abrasive material while maintaining liner integrity in critical containment zones.
Coal Ash and Industrial Waste Ponds
Coal ash, byproduct, and industrial waste ponds require routine sediment management under strict environmental controls. Liner-safe dredging enables the removal of compacted ash and sludge without puncturing synthetic or clay liners. Non-clog EDDY Pump technology ensures consistent transport of heavy material while maintaining controlled contact at the liner surface.
Environmental Remediation Sites
Remediation projects often involve lined containment areas where sediments must be removed without disturbing isolation barriers. Liner-Safe Dredge Options provide remote, low-impact dredging for hazardous or restricted-access environments. Cable-deployed and autonomous systems allow precise depth control and uniform removal across sensitive surfaces.
Industrial Process and Cooling Ponds
Power plants, refineries, and manufacturing facilities depend on lined process ponds for cooling and waste handling. Sediment buildup reduces efficiency and increases maintenance risk. Liner-safe dredging systems restore capacity and flow paths without shutdowns, enabling operators to maintain compliance while protecting long-term liner performance.
Auger Dredge in a Food Processing Waste Pond
Case Study
The Problem
A large food processing facility relied on a poly-lined waste pond to manage organic byproducts, washdown water, and suspended solids from daily operations. Over time, heavy organic material settled and compacted along the pond floor, reducing effective storage volume and disrupting downstream treatment processes. Odor complaints increased, and the facility began approaching regulatory thresholds for overflow risk. Draining the pond was not an option, as it would halt production and require costly temporary containment. Mechanical excavation posed a significant risk of tearing the liner, resulting in environmental exposure and costly repairs.
The Solution
The facility deployed a liner-safe Auger Dredge powered by EDDY Pump. The floating platform allowed in-situ dredging while operations continued. The rotating auger gently loosened compacted organic material without gouging or stressing the liner surface. As material was conditioned, the EDDY Pump transported dense slurry at high solids concentration directly to shore, eliminating the need for dilution water. Cable-based positioning provided precise depth control and consistent coverage across the basin, ensuring uniform removal without liner contact pressure spikes.
The Result
The pond’s full working capacity was restored without draining, shutdowns, or liner damage. Odor levels dropped significantly as stagnant organic buildup was removed. Treatment efficiency improved, and the facility reduced the frequency of emergency maintenance. By establishing a liner-safe dredging routine, the plant eliminated future production disruptions, reduced disposal costs, and extended the service life of the containment system.

Frequently Asked Questions
What makes a dredge system “liner-safe”?
Liner-safe dredge systems are engineered to remove sediment without puncturing, tearing, or scuffing clay, poly, or concrete liners. They use low-ground-pressure designs, controlled contact at the bottom, and precise positioning methods, such as cable deployment, floating platforms, or remote operation, to preserve liner integrity during dredging.
What types of liners can these systems operate on?
Liner-Safe Dredge Options are designed for clay liners, geomembrane liners (HDPE and PVC), and concrete-lined basins. Each configuration is matched to liner type, depth, and site conditions to ensure safe operation without surface damage.
What materials can be dredged from lined ponds?
These systems handle sludge, biosolids, silt, sand, grit, tailings, fly ash, coal ash, and industrial byproducts. EDDY Pump technology moves slurry at high solids concentrations, typically 40 to 70 percent by volume, without clogging or excessive dilution.
Can liner-safe dredging be done without draining the pond?
Yes. Liner-safe systems are designed for in-situ dredging, allowing sediment removal while the pond remains operational. This prevents shutdowns, avoids dewatering, and maintains continuous plant or site operations.
How is the dredging depth controlled to prevent liner damage?
Depth is managed using cable systems, winches, GPS positioning, and operator feedback from shore or a control station. These controls maintain consistent contact pressure and prevent over-penetration, ensuring sediment is removed without stressing the liner.
Which liner-safe dredge configuration is right for my site?
Options range from compact Dredge Sleds and Subdredges to excavator attachments, cable-deployed pumps, Auger Dredges, Autonomous Dredges, and full-scale barge dredges like the T3.
What pump sizes are available across the Liner-Safe product range?
All liner-safe systems use industrial EDDY Pumps ranging from 4-inch to 12-inch. Smaller pumps are suited to confined and shallow environments, while larger pumps support high-production industrial and mining applications.
How do liner-safe systems differ from conventional dredges?
Conventional dredges rely on spuds, high cutting forces, or aggressive excavation, all of which can damage liners. Liner-safe systems eliminate bottom penetration, reduce surface pressure, and use controlled movement combined with non-clog pumping for safer, more predictable results.
Are these systems suitable for hazardous or restricted environments?
Yes. Many configurations operate remotely from shore or from a protected control station. This allows dredging in contaminated, hazardous, or restricted-access basins without placing personnel in the water or on unstable surfaces.
How do liner-safe dredge systems reduce downtime and operating costs?
Non-clog EDDY Pump technology eliminates frequent blockages and the need for manual cleanouts. High-solids pumping reduces water usage and disposal volume. Combined with continuous operation and minimal site disruption, this results in faster projects, fewer shutdowns, and lower total operating costs.
