    How the drainage system works

    While it’s impossible to design a drainage system that can prevent all floods, under today’s standards:

  • underground drainage systems can generally cope with frequent storms that have a 20% chance of occurring each year
  • overland flow paths carry excess floodwater away from properties, preventing flooding during storms with up a 1% chance of occurring each year
  • other benefits to waterways are considered, such as litter traps, stormwater treatment wetlands and stormwater harvesting

    Drain safety

    Entering stormwater drains is illegal, dangerous and in some cases, fatal. Conditions inside a drain can change quickly without warning:

  • Water levels can rise or suddenly arrive from kilometres away, even on a sunny day
  • slow moving flows can become raging torrents
  • poisonous gases and low oxygen areas can be deadly
  • Steep, hidden slopes are easy to slip on and can prevent others from hearing you call for help
  • We can’t cover all stormwater drains and grilles — this would restrict water flow and make litter and debris build up, causing flooding. Warning signs are placed at drain across.
