The Catfish™ mini dredger is compact, robust and easily transportable. Catfish is ideal for cleaning tailings dams, sludge ponds and waste water ponds. The Catfish is readily transportable between job, being less than 2 tons and capable of being placed in a 20 foot container or on a std flat bed track. Transportability enables dam maintenance to be undertaken without decommissioning or dewatering the dam to remove material such as silt, sludge or tailings to return the dam to its original design specification and capacity.
