The North West Treatment Hub (NWTH) services catchments within the North West Growth Centre and priority growth areas spurred by the Metro North-West Line. The NWTH includes the Castle Hill Water Recycling Plant (WRP), Rouse Hill WRP and Riverstone Wastewater Treatment Plant (WWTP).

North Western Sydney will continue to experience rapid population growth in coming years, spurred by investments in housing, job-creating industries, transport projects and other infrastructure. Sydney Water is working closely with customers, the community and government partners to establish new water, wastewater and recycled water services for the North West while supporting the NSW economy and the productivity, liveability and sustainability of the Greater Sydney Commission’s Central River City.

We keep our customers at the heart of everything we do. We want to develop true collaborative relationships, where we are comfortable challenging each other and thinking differently to benefit our business, your businesses and ultimately our customers and the community.

The North West Treatment Hub project has been shaped by the need to:

• Provide the best value solution
• Service growth to 2056
• Ensure servicing meets EPA compliance requirements
• Stage investment in line with forecast growth, and
• Protect waterway health.

This document provides information for an Expression of Interest (EOI) to the market for two (2) projects that are part of a planned program of works across the three north west treatment plants through to 2029.

The two projects are:

1. Castle Hill 2024 Compliance project
2. Rouse Hill 2024 Compliance project

Through this Expressions of Interest (EOI) process, Sydney Water invites proponents (comprising one or more companies covering the required capabilities) to demonstrate that they have the right experience, capability, understanding and commitment to work with Sydney Water to deliver the project outcomes.

This is not just about building infrastructure; we are looking for contractors that will share Sydney Water’s vision for sustainability, enhance Sydney Water technically and culturally, share the benefits of success and share responsibility for delivering the agreed outcomes.
