The flood monitoring device on Foam and Wave streets features flashing lights which activate automatically to warn drivers about oncoming floodwater across the road.
If the floodwater continues to rise to a higher trigger level, Council officers are alerted via text message and close the road.
The lights have been triggered multiple times since being installed after high tides and rainfall on Wave Street.
Council officers have seen drivers stopping and turning around when the lights are activated rather than attempting to drive through the submerged road.
The devices are also allowing Council staff to respond even faster to flash flooding events.
Always remember to never drive through floodwater. It can take just 15cm of flowing water to float a car.
