Tseung Kwan O Desalination Plant (TKODP) will be put into service in 2023. In order to enrich the public understanding of the desalination plant, the Water Supplies Department (WSD) set up an exhibition booth at the “InnoCarnival 2022”, which was held between 23 and 31 October 2022, to explain to the public the reverse osmosis technology adopted in the desalination process and showcase the reverse osmosis module.
