The present two multi-stage flash distillers at Waterport were commissioned in 1984. These plants are each rated at 1,350 cubic metres per day and are able to use waste heat from the electricity generators, at the Waterport Generating Station. In 1991 the desalination plant complex at Waterport was expanded to include two Reverse Osmosis Desalination plants each rated at 240 cubic metres per day. An Agreement was entered into by GOG, in 1990, for the construction of a refuse incinerator that was to produce steam from waste heat and in turn 650,000 cubic metres a year of potable water via three distillation plants. The incinerator is no longer functioning.
