Lifting the lid on wastewater blockages in Perth
While our network is only designed to transport wastewater, we often see things like toys, clothes and even dentures flow through our pipes. When these items enter our wastewater network, they can collect and eventually clog the system resulting in a blockage. This can cause wastewater to head back up into streets, gardens and sometimes even homes, causing what can be a costly and nauseating mess.
Last year, our team responded to more than 2,300 wastewater blockages across Perth at a cost of nearly $3.3 million. So where are Perth's most blocked-up suburbs?

It’s a team effort to prevent wastewater blockages
Here are some ways you can avoid blocked pipes and off-putting smells in your suburb:
- Only flush the three Ps: pee, poo and (toilet) paper. While some wet wipes may be labelled ‘flushable’, they don’t disintegrate like toilet paper, so they should never be flushed down the toilet.
- Scrape food scraps straight into the bin and use a sink strainer to catch any remaining scraps.
- Dispose of cooking oils and fats by pouring them into a container and, once hardened, toss them in the bin.
Wastewater blockages can also occur in your internal plumbing. If your toilet won't flush or there is wastewater overflowing at your home, please call us immediately on 13 13 75 (available 24/7). We can help you identify if the blockage is located on your property or the sewer main, and discuss what to do next.
