The SHARE.MedWATER Project, co-financed by the Interreg Euro-MED 2021–2027 Programme, aims to address increasing water scarcity in rural and island areas of the Mediterranean. By focusing on alternative and non-conventional water sources — such as rainwater, greywater and wastewater — the project promotes their treatment, reuse and sustainable management, offering innovative solutions and participatory governance models.

With a budget of approximately €3,997,735 and a duration of 45 months (September 2025 – May 2029), SHARE.MedWATER involves 10 partners and 11 associated partners across 7 Mediterranean countries.
SHARE.MedWATER develops scalable models for unconventional water reuse across seven countries (Cyprus, Italy, Spain, Albania, Greece, France, and Malta), fostering cross-border cooperation and supporting a sustainable, circular “water transition” in rural and peri-urban areas.

Goals
The Mediterranean is one of the most climate-vulnerable regions, facing droughts, irregular precipitation patterns and increasing water stress that threaten the availability of freshwater resources.
Through a cross-border and inter-regional approach, the project aims to develop innovative solutions for the water transition, defined as a “major structural change to water supply and consumption in a water system”, contributing to the reduction of pressure on existing water resources and to their sustainable management.
In this framework, the project pursues the following objectives:
- Reduce dependence on overexploited freshwater resources through the sustainable reuse of non-conventional water sources.
- Develop and test technologies for the collection, treatment and reuse of rainwater, greywater and wastewater.
- Define and test a hydro-economic model for community-level water management (SHARE.water community), inspired by energy community models.
- Transfer the model to district level and test its integration into existing water systems.
- Develop a Decision Support Tool (DSS) to support stakeholders, public authorities and communities in water management decision-making.
- Strengthen cooperation and knowledge exchange among Mediterranean regions.
Subdivision
- Study: mapping of best practices, regulatory frameworks, and stakeholder engagement.
- Test: 7 local pilot sites and 2 district-scale applications across six Mediterranean countries.
- Transfer: scalability assessment, capacity building, and policy guidance for sustainable adoption.
Expected Impact:
- Reduction of water stress and improved resilience in rural and coastal areas.
- Uptake of innovative, decentralized water reuse technologies.
- Harmonization of regulatory frameworks across the Mediterranean.
- Strengthened transnational cooperation and knowledge transfer for sustainable water governanc
Intended for
- Local communities and citizens in Mediterranean areas
- SMEs and water/environmental sector operators
- Public authorities and local administrations
- Research centres, universities and industry stakeholders
- Civil society organisations and associations
Research Output
- Innovative technologies for unconventional water reuse
- SHARE.water community hydro-economic model
- Pilot implementations and district-level testing
- Decision Support Tool (DSS) for water management
- Policy recommendations and best practice guidelines
- Strengthened inter-regional Mediterranean cooperation

The SHARE.MedWATER project, co-financed by the European Union under the Interreg Euro-MED 2021–2027 Programme, aims to address increasing water scarcity in Mediterranean areas by promoting the reuse of non-conventional water sources and the sustainable management of water resources. The total project budget is approximately €3,997,735, with an EU contribution of around €3,198,188.
