Castle Hill Water Resource Recovery Facility Compliance Project
Abergeldie is working with Sydney Water to deliver the Castle Hill Water Resource Recovery Facility Compliance Project. This upgrade is part of a larger initiative to connect three treatment plants in Sydney’s North-West, forming the new North West Treatment Hub. The hub will create a more efficient, integrated wastewater system to support growth in the area and help keep local waterways clean.
Scope of works
The scope of works involves:
- New inlet works.
- New odour control facility.
- Upgrades to the primary sedimentation process.
- Upgrade to the secondary treatment process including the addition of an anoxic zone.
- New tertiary filters.
- New and upgraded chemical facilities.
- Upgraded disinfection system.
- High and low voltage electrical works.
Innovative solutions to address complex brownfield challenges
The Abergeldie project team has collaborated closely with its design partners-GHD, Thompson Controls, Promech and client Sydney Water to address complex brownfield challenges during the design phase of the project. To address the intricate hydraulic requirements posed by the Peak Wet Weather Flow, an innovative serpentine weir arrangement was developed. This collaborative effort will result in a robust and buildable water-retaining structure.
Community benefits
The upgrades will enhance reliability and increase capacity of wastewater services and improve the quality of the treated water discharged into local creeks and waterways.
