Western Australia's ambitious $2.8 billion Alkimos Seawater Desalination Plant has reached a critical construction phase with the completion of two record-breaking submarine tunnels. The intake tunnel spans 2.5km while the outfall tunnel extends 4km, representing some of Australia's most extensive underwater infrastructure projects. These engineering feats will enable the facility to efficiently transport seawater for desalination processes and manage brine discharge, significantly advancing the state's water security infrastructure and supporting growing population demands.
