The 'Zero Drop' Project

The Zero Drop water resources protection program saves more than 10 million litres of water annually and supports Folegandros' transformation to a 'zero water loss' island.

Through Zero Drop, new seawater boreholes were drilled that supply the 5 existing desalination units with more water for treatment.

Zero Drop is empowering the local community with a view to improving water resources management, educating Folegandros’s schoolchildren and providing capacity building activities and tools for the hospitality sector.

Aiming to promote innovation in the water sector for areas with limited water availability, ‘Zero Drop’ is introducing in Folegandros a new pilot technological application, which generates water by using only solar-powered water vapor condensers. Tapping into an unlimited water source, this application converts atmospheric moisture into high-quality drinking water.


In Folegandros, water is precious! As natural water resources on the island are very limited, most of the island's water supply comes from reverse osmosis units which desalinate seawater. While seawater is unlimited, the treatment comes at a high energy cost and the capacity of the desalination plants mean that during the peak summer months, water supply barely meets demand.

Minimizing water waste can greatly help alleviate the strain on the island's netowork and help ensure you enjoy a stress-free holiday without water interruptions. There are many ways you can help, starting with how you use water in your hotel accommodation.


The ‘Zero Drop’ program is implemented by the Global Water Partnership - Mediterranean (GWP-Med) with the support of The Coca-Cola Foundation, in collaboration with the Municipality of Folegandros.

'Zero Drop' builds on the experience accumulated through 16 years of collaboration between GWP-Med and The Coca-Cola Foundation. Across Greece, Cyprus, Malta and Italy, the GWP-Med/Coca-Cola partnership has yielded 122 technical applications resulting in the saving of 2.1 billion liters of water in Mediterranean water-scarce islands and mainland coastal areas. More than 330,000 beneficiaries have benefited from these interventions, as well as youth engagement and educational activities designed to build capacities around water management.
