North West Wastewater Connection

We're building a more resilient wastewater system
Sydney Water is delivering a transformative investment to ensure our water, wastewater and stormwater systems meet the needs of our customers now and in the future.
The population in Sydney’s north west is expected to double by 2056. Development in the Metro North West Growth Corridor and North West Growth Area has accelerated, so we’re delivering the North West Wastewater Connection project as part of a suite of projects to ensure the ongoing reliability and enhance the resilience of wastewater treatment in the region.
What is the project?
The North West Wastewater Connection project will connect the pumping station at Taylee Place to the Rouse Hill Water Resource Recovery Facility (WRRF) via a new 800 metre underground pipeline.
We will also upgrade the pumping station at Taylee Place and install an emergency generator for back-up power supply. All of this work will reduce the risk of wastewater overflows to the environment.
Early work will start in late 2024. Major construction will start in early 2025 and be completed in 2026.
