CASTWATER is the first Interreg MED project supporting sustainable tourism policies & practices on water efficiency in coastal areas. The transnational challenge is to reduce the impact of tourism activities on environmental heritage and to improve management of water resources. The project's overall objective is to support sustainable tourism water management in Med coastal areas, by improving the monitoring and assessment of the water sustainability performance of the tourism sector.

In this project a consortium of 11 partners representing 10 EU Regions will share knowledge in order to address the need for improving knowledge and practices regarding measurement & assessment methods, about ways to promote awareness on sustainable tourism water management and ideas to support the adoption of water efficiency solutions in the partnership areas.
