Dredging in a dam reservoir


Dredging in a dam reservoir

Dragflow supplied complete equipment for dredging the dam of a hydroelectric power station in Colombia. An ideal solution for high depth dredging.


A Colombian hydroelectric plant needed to remove sand and sludge that have been accumulating at the bottom of the dam wall.


Dragflow supplied an electric dredge pump EL606 S with high depth package as the customer required to dredge up to 45 m below water level. Moreover, a spring driven reel has been supplied for the automatic recovering of the 60m electric cable of the pump. The reel, together with the electric control panel, was installed at the top of the dam wall. The equipment has been the best solution for this job as the hydroelectric plant did not need to stop any electricity production during all dredging operations.
