Watermaster proves success at Narrabeen Lagoon

Oct 09, 2023

The Narrabeen Lagoon in Pittwater, Australia, is the largest coastal lagoon in the Sydney region. It is a very popular destination for enthusiasts of leisure activities such as swimming, kayaking, snorkeling, sailing and fishing.

For locals, it offers a unique lifestyle of outdoor recreation.

The entrance to Narrabeen Lagoon periodically becomes clogged up and needs clearing to prevent flooding.

Recently, the task was assigned to Dredging Systems, who chose Watermaster as their tool of preference to ensure the best outcome.

Mr. Anto Pratten, the founder and director of Dredging Systems, mobilized two amphibious Watermaster dredgers for the project.

This was the first time the removal of excess sand build-up from the Narrabeen Lagoon was carried out hydraulically by suction dredging instead of mechanically excavating.

Watermasters dredged 40,000 m3 of sand into a dewatering basin on the shore through a floating pipeline in one go without having to handle the same materials many times, as was the case earlier with conventional machinery.

The sand was then scooped up by an excavator onto trucks and taken to nearby Collaroy beach, where erosion had depleted the sands.

As a result of Watermaster dredging, the Narrabeen Lagoon area is now more flood resilient. Locals can once again enjoy the outdoors normally.
