SOLLAGUA: Promoting Nature-based Solutions (NbS) for Water Reuse in Southwestern Europe

Water Reuse Europe is happy to announce that the SOLLAGUA project, in which we will be acting as an associate partner, has been approved in 1st Interreg Sudoe call 2021-2027, for a January 2024 start.
The project aims to promote Nature-based Solutions (NbS) for water reuse in the SUDOE region (France, Spain, Portugal cooperation area), which faces major challenges linked to water scarcity due to a semi-arid environment climate change (CC) and a growing population. The project partners will more specifically address these challenges by implementing sustainable water management strategies in 3 rural communities in Portugal, Spain and France.
The overall ambition of the project is to provide a more resilient water supply while offering co-benefits such as climate change mitigation and adaptation. The project will change practices by encouraging the adoption of green/innovative technologies in public procurements. These changes promote a circular economy based on the reuse of local wastewater, while providing a new source of water and an alternative to end-of-pipe installations. This transition is suited to rural areas, which are generally less populated, with a more moderate economy than urban areas.
Achievements include capacity building on NbS for domestic wastewater reuse and the creation of 3 demo sites. These demo sites (location, solution, capacity, design) will be achieved through a new Living Lab strategy focused on water and NbS (NB-WoLL) and its action plan. These Nature-based water-oriented Living Labs (NB-WoLL) will lead to cooperation between governments, universities, companies, and users in an open innovation environment. The NB-WoLL strategy (i) will develop co-creation, (ii) will be oriented towards NBS with (iii) an adaptation to the needs related to water. The action plan mobilizes tools on the costs and benefits of NBS. This will raise awareness and demonstrate the feasibility of these innovations to public/private users.
The project will benefit all those involved in water management. Transnational cooperation will enable the sharing of experiences and lessons learned from the project and promote their replication. This strategy will also ensure alignment of the results with the EU legal framework for reuse.
The Sollagua consortium brings together 10 partners from across the SUDOE region and a range of expertise, including:
