What you can do to help reduce overflows

Good to know

Sewage overflows usually occur during times of significant wet weather. During times like these, sewage is likely to be heavily diluted with stormwater.

When there is persistent heavy rain or a flood event, large volumes of stormwater often get into the sewerage system. This happens due to run-off or incorrect piping that channels stormwater into the sewer. At times like this, sewage can discharge through manholes and other overflow points.

We strongly advise all residents and visitors to stay out of flood-affected waters during and after a storm, as the water may contain snags, sharp objects, stormwater-diluted sewage, chemical waste, fallen powerlines and wildlife.


What you can do to help on your property

You can help stop sewage overflows by checking your downpipe connections and Overflow Relief Gully, and making sure that stormwater is able to run off away from your property without being channelled into the sewer.

Most people don't realise that the sewerage and stormwater systems are two very different networks.

They are each designed to keep stormwater out of the sewage system and vice versa.

Large amounts of stormwater however can enter the sewerage network, especially during heavy wet weather. This increases the chances of sewage backing up and spilling into streets, parks, beaches or even into people's homes.

In many cases the problem is incorrect drainage connections such as downpipes running into the sewer or Overflow Relief Gullies positioned too low.
