Sydney Metro West Western Tunnelling Package

The Sydney Metro West project will support a growing city and deliver world-class metro services to more communities.This new underground railway will connect Greater Parramatta and the Sydney CBD.

The Western Tunnelling Package (WTP) is a vital component in the development of essential metro infrastructure, critical for facilitating the future expansion and economic progress of Greater Sydney. This project plays a pivotal role in building a sustainable transport network, ensuring that mobility services are accessible to all. It encompasses approximately nine kilometres of metro rail tunnels, extending from Sydney Olympic Park to Westmead, and includes two additional spur tunnels branching off the primary tunnels to enhance connectivity and accessibility.

WSce undertook detailed design and Water Services Coordination for wastewater assets as well as potable water assets. In addition, we took a pivotal role in the termination and decommissioning of existing water and wastewater infrastructure.

This included the decommissioning of a wastewater pump station as part of the Sydney Metro West demolition works. Moreover, we played a crucial part in facilitating stakeholder engagement and interface management with Sydney Water. We conducted specialist engineering assessments and led design coordination workshops to ensure a seamless integration of our designs with Sydney Water’s systems.
