NSW Australia
John Holland Pty Ltd
Sydney's north west is experiencing rapid population growth and needs to be supported by essential infrastructure capable of servicing growing demand. In response, Sydney Water is undertaking staged upgrades to the NWTH to support growth to 2056 in line with the NSW Government's long term population forecasts and Sydney Water's operating licence obligations. This requires balancing treatment capacity upgrades, improving environment and community outcomes and complying with environmental regulatory requirements as the NWGA develops. In particular, the NSW EPA's Hawkesbury Nepean Nutrient Framework imposes new nutrient load and concentration limits in our Environment Protection Licences (EPLs) effective from mid 2025. Upgrades to the NWTH in response to new EPL load and concentration limits as well as EPL pollution reduction program (PRP) obligations are currently underway.
The upgrade works involve upgrades at both Riverstone WRRF and Rouse Hill WRRF as per below:
1. Rouse Hill Water Resource Recovery Facility (WRRF):
- Amplification and augmentation of the secondary treatment process
- Odour containment and treatment from new odorous sources
- Augmentation of the disinfection facilities
