Could a radical Australian idea for floating self-powered desalination reservoirs be a timely solution for water supplies, changing the way we handle water on land? Enter the 'Aquadam Project' - a starkly innovative scheme to capture and store rainwater, stormwater and desalinated seawater in a flexible, floating dam sited some 2 to 5 km out to sea. A guaranteed supply of purified water will then be piped to neighbouring cities or towns, easing the growing burden on catchments and rivers.
