Wastewater treatment works
We manage a network of wastewater pipes and wastewater treatment works (WWTW) throughout the Lower Hunter. Find out where each facility is located and wastewater is treated.
Wastewater systems
Here you'll learn about our entire wastewater treatment process, from the treatment plants and wastewater quality to beach water and the environmental safeguards we have in place.
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.
Beach water quality
We're committed to protecting the environment, especially our oceans. Find out the measures we take to monitor and protect our pristine beaches along our coastline.
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.
Pollution monitoring results
We collect pollution monitoring data as required under the Environment Protection Licences (EPLs) issued by the NSW Environment Protection Authority (EPA).
