Keeping our sewers healthy

Keeping our sewers healthy

To help us keep our sewers healthy, minimising the number of sewer blockages and overflows, we need your help.

When items other than the three Ps – paper, 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, also known as a choke, which can lead to overflows inside your home and property, and external overflows in your street which can impact on your community. These items can also cause issues at our wastewater treatment plants as they build up and need to be physically removed.

Spread the word and keep our 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. 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, and
  • condoms.

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

Smart technology and our sewer cleaning program

Our targeted sewer program sees us travel around South Australia to clean the 9,000km of sewer network. In the past year, we cleaned around 250km of mains – that’s equivalent distance from Adelaide’s CBD to the Victorian border!

We are trialling wastewater technology in Stonyfell, having installed smart sensors to provide us with data to monitor levels and proactively maintain the network and prevent a choke.
