Can we save 25% of the water we use?


The first stage of the Water Saving study is now complete: total water consumption and water supply on the eight islands Tilos and Ithaca (Greece), Vis and Lastovo (Croatia), Sein and Houat (France), Cape Clear and Inis Oírr (Ireland) have been mapped, in detail. Now Mayors and Water Officers take next step, gathering for a challenge meeting on island Vis, September 22-24.

The challenge is: can we save 25% of the water we use? Is it possible to achieve such savings through a balanced blend of actions including information, household technologies, industrial technologies, governance and pricing?

If so, these islands will save 180 million liters of fresh water. If one hundred islands join the challenge, 18 billion liters of water will be saved. If we can extend this knowledge to all of Europe’s 2,400 islands and coastal communities, the saving on one of nature’s most precious assets is almost unimaginable.

The project’s sponsor, EU Parliamentary, former Foreign Minister of Croatia, Tonino Picula, is hopeful:

  1. There is a solution to our water
    problem.We save it before it leaves
    our homes and by the time it goes
    through a process it’s drinkable.

    • Dear Michael, how interesting! This is part of what is called non-conventional water resources, as researched by for example prof Michale Scoullos, Athens. Please tell me more: how do you go about it, what technology do you use, what are the costs, how many households are doing like this? Kind regards, Christian
