Riverstone and Rouse Hill - Growth REF Addendum is now on public display
In 2022 we publicly displayed a Review of Environmental Factors (REF) outlining our plans, including to build a pipeline. We had originally planned to build a new pipeline to transfer partially treated wastewater from Castle Hill WRRF to Rouse Hill WRRF, and from Rouse Hill WRRF to Riverstone WRRF for further treatment.
We have refined these plans and have made some changes to the proposed designs. Most of these won’t have a substantial change in how the project impacts the community. One of the key changes is that we are now proposing to use a more efficient process called carbonisation to treat and reuse biosolids (a by-product of the current treatment process) at Riverstone WRRF.
To provide the community with more detail on the proposed changes, a Review of Environmental Factors Addendum (REFA) has been prepared.
The REFA looks at all the potential benefits and environmental impacts of the project as we build it and once it's up and running. The REFA needs to cover all scenarios, even though there will be opportunities to improve or even eliminate some of these impacts as we continue to fine-tune this project. It includes:
- the background to this project
- proposed construction activities, including work locations within the Riverstone and Rouse Hill Water Resource Recovery Facilities
- Potential environmental impacts, including noise, traffic and access.
The REFA is on display from Monday 17 June to Tuesday 9 July 2024.

Feedback from the community is invited during this time via email at and you can email us NorthWestTreatmentHub@sydneywater.com.au
You can view and download the REFA from the Document Library.
We will continue to engage with stakeholders and the community throughout the project, and keep you updated on work in your local area.
If you have any questions about our plans, please come along to a community information session or attend our webinar in the coming weeks. We’d love to hear your thoughts – check out the timetable below.
