Sewage (wastewater)

If you notice damaged or overflowing sewerage mains or access-holes, please call us on 07 3412 3412 as soon as possible. 

If you have a problem with the sewerage pipes on your property, please call a licensed plumber in the first instance. 

We repair blocked and damaged sewerage mains outside of your property boundary.

Sewage Overflow

Heavy rain can cause stormwater to flow into the sewerage network. This can overload the network and make it overflow. Stormwater enters the sewerage network through:

  • illegal roof and property connections
  • damaged property drains
  • unsealed access-hole lids
  • leaks in the network due to damage.

We have designed our sewerage system to overflow at set points. This stops sewage from overflowing in private properties. To learn more, please download the following documents:

Overflow relief gully

An overflow relief gully (ORG) is a plumbing fitting that releases sewage if there is a blockage or overload in the network. The ORG grate will release the excess pressure and direct sewage away from your home. For more information, please download the Overflow relief gully factsheet (PDF 315 KB).

Risks of a sewage overflow

Sewage can contain micro-organisms such as viruses, bacteria, fungus and parasites. These can be harmful to humans, animals and the environment.

Sewage overflow can lead to illnesses such as:

  • gastroenteritis (diarrhoea or vomiting)
  • giardiasis and cryptosporidiosis (severe stomach cramps, diarrhoea or vomiting)
  • viral infections such as hepatitis (liver infections)
  • infections of the skin or eyes.

You can lower your risk of exposure by:

  • washing your hands
  • covering wounds
  • disinfecting wounds straight away if you have been in contact with sewage.

Sewage can also impact the water quality of our streams if it overflows near waterways.

Reducing sewage overflow

We work to reduce overflows by:

  • regularly inspecting and repairing damaged pipes and access holes
  • providing controlled overflow points
  • monitoring the performance of the network
  • reducing how much stormwater can get into the sewerage network.

You can reduce the amount of stormwater going into the sewerage network by:

  • making sure your roof water or garden drainage do not connect to overflow relief gullies
  • replacing faulty and damaged household drainage pipes.
