Keeping our sewers healthy

Keeping our sewers healthy

We need your help to keep South Australia's sewers healthy, and limit the number of blockages and overflows.

When items other than the three Ps – paper (toilet), pee and poo – are flushed down the loo, or incorrect items are put down the drain, they make their way into sewer pipes and can easily become trapped. This causes a blockage, which can lead to overflows inside your home, yard or in your street, which can also impact on the local environment. These 'unflushable' items can also cause issues at our wastewater treatment plants, as they build up and need to be removed.

Spread the word and keep your sewers healthy by only flushing paper, pee or poo!

What not to flush

It’s simple - if it’s not paper, pee or poo, do not flush it down the loo. Cooking fats, greases and oils must not be put down the drain, rather let them cool and then put them in your bin.

The most damaging items are:

  • sanitary pads
  • tampons
  • wet wipes
  • condoms.

These items are not designed to easily break down in water, rather they get stuck in our pipes, tangled within tree roots in search of water, or collected at wastewater treatment plants and then taken to landfill. Wet wipes and feminine hygiene products account for around 90 per cent of materials removed from blocked sewers.

Smart technology and our sewer cleaning program

Our targeted sewer cleaning program sees us travel around South Australia to clean the9,000 kilometres of sewer network.

We are trialling smart wastewater technology in several targeted Adelaide suburbs, with smart sensors providing us with data to monitor sewage levels and proactively maintain the network to prevent a pipe blockage.
