Supplementing Perth’s drinking water supply

Alkimos Seawater Desalination Plant

As a part of Perth’s integrated water supply strategy, the Western Australian Water Corporation is looking to construct the Alkimos Seawater Desalination Plant to supplement the current metro water supply. We were brought in coordinate the approvals strategy and ensure the development could meet environmental objectives.

The fully integrated project considered the full spectrum of environmental habitats, from terrestrial and coastal to the offshore marine environment—needing our team’s multidisciplinary approach.

We prepared the environmental gap analysis, outlining the key technical environmental data needed to support the development of the public environmental review, and we also coordinated the public environmental review process. Our supporting documents included technical risk assessments (satisfying state and federal legislation), the construction environmental management framework, and a biodiversity offset plan.

The turnaround time needed was limited, but we managed to deliver within the Western Australian Water Corporation’s eight-week timeframe—helping to inform the next stages in the process.
