Water Corporation’s Seawater Desalination Plant Construction

Water Corporation has advised WAFIC that marine construction for the Alkimos Desalination Plant is scheduled to commence in mid-December 2025 and is expected to be completed by mid-2026.

Two construction barges will operate at both intake and outfall locations during January and February 2026. From March 2026, one barge will continue operating at the outfall location until construction is completed. Marine exclusion zones will be in place around both locations for the duration of the works.

Please refer to the attached information here for details on the locations of the exclusion zones.

Water Corporation has requested fishers to remove all equipment from the marine exclusion zone as soon as possible and stay clear of the area during construction. Removal of fishing gear such as cray pots and octopus traps from the area will ensure gear is not inadvertently damaged.

Water Corporation has confirmed that DOT temporary notice to mariners (Exclusion Zones) came into effect from Wednesday, 10 December.
