Where your sewerage goes

Western Water has seven recycled water plants that receive wastewater collected from our sewerage systems. Wastewater is treated to produce recycled water which is a valuable resource.

Recycled water produced from treated wastewater is beneficially reused locally for open space irrigation and approved agricultural uses. At most plants, recycled water can also be discharged to waterways or land as per requirements set out in the plant’s EPA Licence.

As the local population grows, generating more wastewater, our challenge is to find beneficial uses for the additional recycled water produced.

The below table shows where wastewater is treated for the towns Western Water services.

Find out about how recycled water is treated and what the different classes mean.
