Rainwater Harvesting in the Mediterranean:Experiences from Implementation in islandsKonstantina Toli, MSc.Programme OfficerGlobal Water Partnership - Mediterranean
Water resources in the Mediterranean Water is a rare and fragile resource in the Mediterranean.The Mediterranean climate is typified by an enormous irregularity in the distribution of rainfall in space and time.

Water resources in GreeceGreece is a typical Mediterranean country, with unbalancedrainfall, where integrated water management systems are stilleither deficient or absentManagement efforts areconcentrating on theimplementation of provisions ofthe Water Framework Directive.There are parts of the country thatare under severe water stress, suchas numerous islands of the AegeanSea.

Continuing growth puts pressures on vulnerable water resources Causes Consequences• Demographic growth • Threats to the quantitative• Urbanization and qualitative regenerative• Intense irrigation capacities of freshwater• Touristic activities • Degradation of the quality of freshwater and ecosystems• Disposal of effluents • Growing cost of water• Climate Change
Urgent need for Non Conventional Water Resources• There is an urgent need to enhance water efficiency and to explore further alternatives to ensure water availability using innovative approaches.• The revival of traditional water harvesting and management techniques, which have been overlooked in favour of modern technologies, sometimes less sustainable, can be a move in this direction.
Rainwater Harvesting Project Aims & Objectives To position rainwater harvesting as a helpful tool for climatechange adaptation at local level. To promote rainwater harvesting as a sustainable way ofproviding community access to water in water scarce areas,thereby contributing to the improving ecosystem conservation. To promote multi-stakeholder partnership for local rainwaterharvesting initiatives. To promote knowledge and sharing of experiences on aspects ofrainwater harvesting systems and approaches. The project is essentially a “demonstration case” aiming at educating and stimulating people of all ages towards a “new” (eventually not so new) “water culture” necessary for addressing the current water needs.
RWH Project ActivitiesInstallation of Rainwater Harvesting Systems in selected publicbuildings/properties (schools, town halls etc.). The harvestedrainwater is for several non-potable uses (watering, toilet flushingetc.) contributing to water supply consumption reduction andwater saving.All installations are harmonized with the architectural identity ofthe islands and the landscape. They include both above- andunder-ground tanks.Educational Programme: (i) Production of educational material,‘The Gift of Rain’ (ii) Educational programme for students aged10-15 years old (iii) Teacher training on education for sustainabledevelopment, focusing on water issues.Training Seminars for local technicians/workers (constructionworkers, plumbers, engineers etc.).
Rainwater Harvesting Project 2008-2011 13 Cycladic Islands 2348 students participated (1298 in Cyclades & 1050 in Athens) 326 teachers trained91 technicians and citizens trained/informed* Installation of 15 RWH systems Repair of 15 RWH systems Installation of 1 Greywater system Estimated rainwater yield: 4.5-5.0 million liters of water *the 2011 Technician Training is still pending
A Success Story Rainwater Harvesting Project 2008-2011 Local Authorities Engagement & Ownership Acknowledgment, SustainabilityAwareness Raising on Rainwater Harvesting and water saving practices Publicity and Dissemination Award as Best Environmental Educational MaterialRegional Conference on Advancing Non Conventional Water Resources Management, Athens 14-15 September 2011
Other ActivitiesStakeholder Analysis & Consultation in Sifnos IslandExpected Outcomes:Stakeholder mapping and analysis (background & interview based),Stakeholder Consultation for (i) prioritization needs, (ii)development of shared vision, (iii) identification of potentialpractical applications, (iv)(potentially) voluntary agreementamong stakeholders for better water management through NCWR. • King’s College London • GWP-Med • Cornell University
Lessons LearnedNEEDS A new water culture Education for Sustainable Development Application of Non Conventional Water Resources Management methods and practices adapted to local needs Partnership – Stakeholder InvolvementOPPORTUNITIES Replication as best practice Knowledge Sharing
