Water Infrastructure

The Water Infrastructure upgrade addresses the critical need for a robust water supply network that can adequately support the increasing demands of both tourists and island businesses in peak visitation periods.

With a $34.1 million investment, the project aims to revamp the island’s outdated system, including the desalination plant, water mains and distribution network. This strategic upgrade is vital for meeting both current and future water demands as well as enhancing firefighting capabilities. The Water Infrastructure Master Plan guides the multi-stage delivery, ensuring a sustainable and efficient water service for the next two decades.

This project is a key priority of the Rottnest Island Management Plan 2023-28, which includes a strategic focus on strengthening the island’s infrastructure to address legacy issues and ensure the island can sustainably meet demand over the next two decades.

Early works completed to date include the installation of new water mains within Kingstown and the Settlement Mall in 2021, and South Thomson, Longreach and Fay’s Bays in 2022.

The expected completion dates for the remaining areas are:

• Geordie Bay – Due to be completed over winter 2024
• North Thomson – Planning underway to be completed in winter 2025
• Upgrade of water production infrastructure – Planning underway to be completed in Winter 2025
