Keep stormwater out of sewer
We live in one of the most beautiful parts of the world and our environment is particularly close to our hearts. Tasmanian is home to some of the most stunning waterways and parklands and it is important that we all do our bit to protect the environment.
Stormwater inflow and infiltration
Our sewerage network is not designed to manage the inflow and infiltration of stormwater during rainfall.
Inflow is where stormwater enters the sewerage network, generally via private plumbing that is incorrectly connected to the sewer.
Infiltration is stormwater entering the sewerage network, generally by seeping through cracked, or unsealed underground infrastructure.
Below is a diagram that shows a correctly plumbed and incorrectly plumbed property.

The effect of inflow and infiltration
When the amount of stormwater entering the sewerage network exceeds the network's capacity, there is potential for the following:
- overflows to creeks, rivers and parklands
- increased risks to the health of our waterways and local environment
- increased sewage pumping and treatment.
How can you help?
We all have a responsibility to minimise sewer overflows by being aware of and fixing incorrect connections on our properties. we will be checking your downpipe is connected to the stormwater system, not the sewer network.
If an incorrect connection is identified you should:
- Contact your local council for advice on connecting to the stormwater system.
- Contact a licensed plumber to fix any stormwater cross-connections or sewer defects.
- Ensure your properties Overflow Relief Gully (ORG) is raised above ground level. Contact a licenced plumber before raising an ORG, if it is raised too high it can cause problems to your property.
