The Water Corporation propose to construct a seawater desalination plant to supply potable water to the town of Onslow, WA. Seawater intake and brine wastewater release will occur in Beadon Bay, approximately 1 km seaward from the shoreline. The desalination processing facility is to be located at Lot 551, 552 and/or 553 Beadon Creek Road, Onslow.

The proposal will involve the installation of permanent subtidal infrastructure in Beadon Bay (intake head, brine diffusers and transport pipes), a land-based processing plant, and piping to the existing town storage tanks.
