Our sewer network

All the water that is used at home, at work and in the community flows through a complex network managed by Hunter Water. There are things you can do to help us keep this network operating efficiently.

Recycling and Reuse

The used water (sewage) from homes, factories, shops, and other places is often called wastewater, but it's no longer considered a waste product. It's a valuable resource we can recycle and use in new ways. Recycled water is used in homes and gardens, in industry, and on sporting fields. Biosolids, also from our wastewater treatment plants, is beneficially re-used in mine site rehabilitation and farming.

Wastewater quality

We carefully monitor and treat our wastewater, ensuring that it complies with Environment Protection conditions. See how each wastewater treatment works (WWTW) is performing in our monthly reports.

Additional information

Wastewater and COVID-19

There is no evidence that COVID-19 has been transmitted to people via wastewater. COVID-19 is susceptible to our current treatment processes. Sewage also contains detergents and other substances that inactivate (kill) the virus before it reaches the treatment plant.

As part of our day-to-day operations, we have stringent hygiene and safety measures in place across our treatment plants. Our workers continue to employ best practices for protecting water quality and their occupational health, including the use of personal protective equipment.

The NSW Health COVID-19 Sewage Surveillance Research Program tests untreated sewage for fragments of the COVID-19 virus to provide data to support NSW Health's response to the pandemic.
