With the threat of Cyclone Alfred overhead, authorities in Goodna are relying on innovative flood protection devices to shield critical electrical infrastructure from potential damage. The installation of Flood Tuff units is part of flood resilience measures ahead of expected heavy rainfall and potential inundation.
Learning from the 2022 Floods
The February 2022 floods saw Brisbane record almost 793mm of rain in just six days, inundating key transport corridors and causing widespread damage to Intelligent Transport Systems (ITS) equipment. The Queensland Department of Transport and Main Roads (TMR) worked rapidly to restore operations but faced delays of up to 15 months due to supply chain shortages.
To prevent future disruptions, engineers designed the Flood Tuff system, drawing inspiration from Edmond Halley’s 1690 dive bell invention. The units, made from low-density polyethylene, can be quickly deployed and protect electrical infrastructure from water damage up to five metres in height.
How Flood Tuff Works
Flood Tuff units are lightweight, compact, and easily installed in high-risk flood zones. Developed in collaboration with Tri Underground and the University of Queensland, the design features an active pressure system powered by compressed air, ensuring continued protection even in extreme conditions.
According to the State, the ITS network is critical for managing traffic flow, speed regulations, and road safety signals. Ensuring these systems remain operational during flood events is essential for public safety and transport efficiency.
Community Reaction in Goodna
Locals have taken to social media to share their curiosity and concerns about the new installations. Some questioned their purpose, while others welcomed the initiative, given the area’s history of flooding. One Goodna resident wondered what they were, while another joked if the State could put a massive one over a house.
Future Implications and Preparedness
With 36 Flood Tuff units now manufactured and deployed across 29 sites in Queensland, the technology represents a proactive approach to flood resilience. Residents in Goodna and other flood-prone areas are advised to have emergency kits ready, stay updated with official warnings, and take necessary precautions.
