What do Superman, Spiderman and a reusable aqua barrier have in common? They’re all superheros of course!

While the aqua barrier doesn’t have super strength or x-ray vision, it has been recognised for its sustainability superpowers when it comes to protecting a section of the Tom Bateman wetlands near the Cameron-Elliot footbridge.

The temporary water-inflated dam was used to reduced environmental impacts to the wetlands and has fittingly been recognised at the 2024 Civil Contractors Federation Awards for its effectiveness.

The aqua barrier was used to divert water from the footbridge construction site, trap sediment and prevent it from entering the wetlands – ultimately safeguarding the wetland's water quality and ecosystem. To further enhance sediment control, a silt curtain was also used.

Following installation of the aqua barrier, fauna traps were also set up to relocate turtles and fish and minimise any potential disturbance to the endemic fauna.

NEWest Environment and Sustainability Manager, Martin Von Kasche said the aqua barrier was key to safeguarding the wetland’s water quality and existing ecosystem.

"Before installing the aqua barriers, we carried out comprehensive planning to ensure the innovative system would protect the delicate wetland ecosystem while allowing construction activities to proceed,” he said.

“Thanks to the aqua barriers, we have been able to maintain the integrity and marine life in this wetland area.”

Given the overwhelming success of the aqua barrier, this humble superhero will certainly be making an appearance on future works across METRONET projects.
