SOLLAGUA is a research project funded by the European Interreg SUDOE programme. Its aim is to promote nature-based solutions (NBS) for wastewater reuse in France, Portugal and Spain. The initiative seeks to address shared challenges such as water scarcity, climate change and growing water demand in particularly vulnerable environments.
The project, which will run until January 2027, is implemented by a consortium of ten organisations coordinated by the University of Toulouse.
At the heart of SOLLAGUA is the NB-WoLL (Nature Based Water-Oriented Living Labs) strategy, a network of collaborative spaces focused on designing, validating and implementing sustainable solutions for the management and reuse of reclaimed water in rural environments.
These living labs bring together public authorities, companies, research organisations and other stakeholders in the water ecosystem to develop solutions tailored to the actual needs of each territory. Through participatory methodologies and co-creation processes, the NB-WoLLs promote knowledge exchange and accelerate the adoption of innovative strategies related to water reuse, climate resilience and the circular economy.
SOLLAGUA Nexus is an online platform developed by the project consortium to intelligently connect public and private stakeholders involved in water reuse and the circular economy.
The tool helps identify needs and capabilities related to the supply and use of reclaimed water, fostering new collaborations, joint projects and cooperation opportunities among organisations in France, Portugal and Spain.
