Floods are a frequent issue across Victoria and in many parts of Gippsland. Floods place pressure on infrastructure and cause damage to homes and businesses.
For water corporations floods can cause issues with sewer systems that become overwhelmed by stormwater and place pressure on water treatment systems around rivers that have been inundated by silt and soils.
For information on preparing your home or business for flood visit the SES Floodsafe page.
Impact on water supplies
Flood events may impact on water supplies if a treatment plant draws water from a river or creek. Run off of soils and silts may restrict the capacity of the plant to treat the raw water which may impact on the quantity and quality of supply.
Gippsland Water will communicate with customers and the wider community through traditional media and social media during such an event.
Impact on sewer systems
During flood events sewer systems can be inundated by storm water. These systems are not designed for such inflows as their primary purpose is to carry sewage from customer’s homes to treatment centres.
When systems are inundated by stormwater this places pressure within the system which can lead to sewage overflows into the environment.
This possibility reinforces the SES message to never drive, walk or cycle through flood waters.
Ensure you have an alternative water supply
In the unlikely event that water supply is disrupted you will need to access water for daily needs.
The Australian Red Cross suggests that you have three day’s supply of water on hand in the event of an emergency. Find out more on the Australian Red Cross website.
Ensure your stormwater does not enter the sewerage system
Inundation of the sewerage system is a major risk during flood events. This occurs largely when households allow storm water to enter the system through what is known as an overflow relief gully (ORG).
These are designed to allow a household sewerage system to overflow in a relatively contained area should the system be blocked by a tree root or other obstacle.
By allowing rain water drainage to enter the sewer system in this way households and businesses are increasing the risk of sewer overflows in another part of the system during rain events.If you are not sure whether your ORG is connected properly, contact Gippsland Water.
