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.

    The work is subject to a Review of Environmental Factors (REF). The Addendum includes a detailed Noise and Vibration report that predicts the project's possible impacts. It does this by measuring current noise levels at certain locations and considering typical construction activities, including specific machinery to be used, to come up with a worst-case scenario for the local community.

    The addendum considers project mitigation measures such as temporary noise barriers that will reduce noise while the works are underway. This helps us predict which residents and businesses will be most impacted at various project stages.

    The contractor will monitor compliance with the recommended noise and vibration levels throughout the project to ensure they do not exceed allowable levels. We will speak to the community before and throughout the project, to ensure we address any specific concerns.
