Water Infrastructure

Enhancing Rottnest Island with vital infrastructure upgrades to overhaul the ageing water production and supply network.

Overview

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.

The project aims to revamp the island’s outdated system, including the desalination plant, water mains and distribution network and essential services corridor. 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 future demand.

Frequently asked questions

The Northern Service Corridor is an alignment of buried infrastructure that includes water, communications and power.

Water and power infrastructure works optimally when reticulated in loops, as this provides electrical and hydraulic redundancy. The northern service corridor will complete the northern arm of the ‘ring main’.

The location was determined following extensive consultation with stakeholders across several years. The main factors affecting the choice of location were protection of environmental and cultural heritage, as well as constructability and engineering viability.

Construction works are projected to take up to four months to complete, commencing in June 2026 and concluding in September 2026.
