Ensuring water quality
To meet the increasing demand and ensure water quality during challenging conditions, a new facility called the Prospect Pre-treatment Plant will be built near the Prospect Water Filtration Plant.
About this project
We're building the new Prospect Pre-treatment Plant (PPTP) near the Prospect Water Filtration Plant (WFP), which supplies drinking water to over 4.2 million customers and 85% of Greater Sydney. Suez Acciona Joint Venture has been contracted to design and construct the PPTP for Sydney Water.
This project is a critical upgrade to Sydney's water supply system. It will ensure resilience and reliability in delivering safe drinking water, especially during extreme weather events such as storms, droughts and bushfires.The PPTP will provide additional treatment for raw water to support the water filtration plant. This will allow the Prospect WFP to continue providing safe, secure and reliable drinking water during periods where raw water quality has been impacted.
The PPTP augmentation and upgrade program is divided into 3 packages:
- Package 1: Construction and operation of the new 500 ML/day PPTP
- Package 2: Flood works, including a new tilting gate emergency release point to Prospect Reservoir and decommissioning old assets
- Package 3: Upgrades to the Prospect WFP, including solids and residuals handling and new backwash recovery pumps.
Packages 2 and 3 will be delivered by Prospect Water Partnership and will be subject to separate environmental impact assessments.
Package 1 is currently being built. This includes:
- New raw water inlet channel to transfer raw water from Channel 1, which will be screened
- Raw water pumping station to pump screened raw water to the pre-treatment technology process, with provision for emergency discharges to Prospect Reservoir
- Chemical storage and handling systems to enable dosing of chemicals to aid the pre-treatment process
- Infrastructure that discharges the pre-treated raw water into Channel 1, with the pre-treated raw water mixed with other raw water sources
- Infrastructure that dewaters and out-loads for off-site disposal the settled solids from the pre-treatment technology process
- An administration building, including control room, office and a car parking area
- Laboratory, equipment stores area and maintenance workshop
- SCADA control system to enable automatic operation of the pre-treatment plant facilities and integration with other assets
- Site services, including access road, power (low-voltage and high-voltage), water, wastewater, stormwater, compressed air, telecommunications, firefighting, site fencing and gates, security systems, etc.
The plant is expected to be operational in late 2027.
Benefits
- Consistent high-quality drinking water, even during adverse conditions like storms, bushfires and droughts
- Supports the main filtration plant, ensuring a reliable water supply for Sydney's growing population
- Reducing operating costs due to improved raw water quality that is more efficient and treatable.
