Preparing for floods
Floods can impact sewer systems, which can become overwhelmed by stormwater
They can also put pressure on water treatment systems near rivers that have been inundated by silt and sediment.
How we prepare for floods
Impact on water supplies
Flood events may impact water supplies if a treatment plant draws water from a river or creek. Run-off of sediment and silt may reduce a plant's capacity to treat raw water at the usual rate.
If this happens and water supplies are interrupted, we’ll aim to notify customers in several ways, including text message, our website and social media.
To make sure you can be quickly contacted, check your most up to date mobile number is registered with us or call our Customer Care team on 1800 050 500.
Impact on sewer systems
Sewer systems can be inundated by stormwater during flood events.
This can lead to wastewater overflows into the environment, which can be hazardous. Follow the SES guidance: never drive, walk or cycle through flood waters.
If you notice a potential sewer spill, call our 24/7 faults and emergencies line on 1800 057 057.
What you can do to prepare for a flood
Ensure you have an alternative drinking water supply
In the unlikely event that your water supply is interrupted, you'll need to access drinking water.
Three litres per person per day is the recommended amount. Drinking water can be stored in receptacles like water bottles or jugs.
You can also consider storing additional water for drinking, cooking, brushing teeth, and other uses.
Ensure stormwater does not enter the wastewater system
Sewerage systems on your property can become inundated during flood events. This can occur when stormwater enters the system through such as an overflow relief gully (ORG)
Overflow relief gullies are designed to allow a household sewerage system to overflow in a relatively contained area should the system become inundated with flood water, blocked by a tree root or other obstacle. Make sure these are not covered and are free from obstructions.
Rain water drainage entering the sewer system can increase the risk of sewer overflows during rain events.
If you’re not sure whether your ORG is connected properly, call us on 1800 050 500.
Who is responsible for managing stormwater?
Local councils manage the stormwater drainage network downstream of private properties (public drains). Property owners are responsible for drainage up to the point of connection with council’s system. For more information, contact your local council or visit your local council's website.
