January, 2019


This Northern NSW WWTP site was undergoing a major upgrade and a major element of this project was that two sludge lagoons needed to be dewatered to provide space for a future solar farm.

Our Approach:

650  dry tonnes of sludge was removed using our DINO 6 auger suction dredge and dewatered via our VITONE V9 centrifuge. The material was subsequently transported to the designated stockpile on site for further consolidation (pictured).


The two lagoons were comprehensively desludged and back filling was then performed on Lagoon One to allow for re-purposing. Dredging Solutions were  subsequently engaged  to assist with removal of sludge from the digesters on site during the same upgrades.
