Green Light for Alkimos Seawater Desalination Plant in WA

Home » News » Green Light for Alkimos Seawater Desalination Plant in WA

In a significant stride, the Alkimos Seawater Desalination Plant (ASDP) gained approval from state and federal regulators. The Commonwealth Department of Climate Change, Energy, the Environment, and Water gave the green light to the 100 billion-litre-a-year plant. This marks a crucial milestone for ensuring a reliable water source for Perth’s residents.

This milestone follows the thorough evaluation by the Western Australia Environmental Protection Authority. Subsequently, conditions received approval from Western Australia Environment Minister Reece Whitby in August 2023.

These ministerial conditions outline how the Water Corporation will handle the plant and its infrastructure. They stress responsible environmental stewardship on both terrestrial and marine fronts.

Ensuring a commitment to sustainability, the approved conditions mandate achieving net zero scope one and two greenhouse gas emissions throughout the construction and operation phases. This involves strategic measures such as procuring renewable energy to fulfil the plant’s total annual energy requirements.

Securing Tomorrow’s Water: Alkimos Seawater Desalination Plant Milestones Propel WA’s Water Security

Gaining development approval in October 2023 from an independent Development Assessment Panel, the Alkimos Seawater Desalination Plant (ASDP) project paves the way for initial site works. These are set to commence later in the same year.

Originally revealed in June 2022, the ASDP is crucial for over 2.5 million Western Australians reliant on the Water Corporation’s Integrated Water Supply Scheme for drinking water. The colossal project will unfold in two stages, each producing 50 billion litres annually, with water anticipated to flow by 2028.

Designed with meticulous care for the environment, the plant will nestle behind expansive, vegetated dunes, acting as both a visual shield and noise buffer. During construction, ASDP will employ a specialized tunnel boring technique to minimize disturbance to the seabed and beach.

The Western Australian government underscores the project’s significance with a committed financial allocation of $2.1 billion from consecutive state budgets.

Simone McGurk, Western Australia’s Water Minister, noted, “This marks a significant milestone for a project crucial to long-term water security.” Recognizing climate change’s impact on traditional water sources, McGurk stressed diversifying supply methods. She commended the state’s pioneering role in large-scale desalination.

Reece Whitby, the Environment Minister, echoed, “Water security amid climate change is a global challenge.” He expressed confidence in the Water Corporation’s ability to execute the ASDP safely and sustainably, adhering to stringent environmental conditions. Whitby emphasized the contribution to broader efforts to decarbonize Western Australia’s electricity grid.

As the Alkimos Seawater Desalination Plant surges forward, it signifies not just a solution to water scarcity but a testament to Western Australia’s commitment to responsible resource management in the face of a changing climate.
