Closed 25 Oct 2022

Opened 28 Sep 2022


The Water Corporation is proposing to construct and operate the Alkimos Seawater Desalination Plant, a 100 gigalitre per annum seawater desalination plant and a 6 gigalitre per annum groundwater treatment plant, at the Alkimos water precinct. The project includes a 33.5 kilometre pipeline from the Alkimos site to the Wanneroo Reservoir.

Water Corporation has prepared an Environmental Review Document (ERD) in accordance with Environmental Protection Authority (EPA) procedures and is released for public review. The ERD describes the proposal, examines the likely environmental effects, and the proposed environmental management procedures associated with the proposed development.

The ERD also satisfies the requirements for an accredited assessment under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) (EPBC Ref: 2019/8453) and includes assessment of potential significant impacts of the proposal to Matters of National Environmental Significance (MNES).
