Dredging and Dewatering


The client was required to empty one of their blowdown ponds in order for them to be relined with a dual layer of HDPE. Dredging Solutions were engaged to remove 1,400 dry tonnes of sediment.

Our Approach:

We utilised our remote controlled FLUMP auger suction dredge to harvest and pump in-situ material, via an inline polymer dosing system, to a tiered configuration of bunded geotextile dewatering containers. The close proximity of the dewatering areas to the pond meant that filtrate released from the dewatering tubes was able to be captured and returned via a gravity drainage process.


The initial proposed 1,400 dry tonnes of material was successfully removed within the required time frame and Dredging Solutions were quickly engaged to undertake a subsequent dredging campaign on a neighbouring blowdown pond.
