Best suited for
This approach is particularly suitable for river basins with connected alluvial aquifers where groundwater and surface water exchanges naturally occur. It is most relevant in regions experiencing recurring droughts, declining summer baseflows and rising water temperature stress, especially where agriculture, ecosystems and urban water demand depend on the same hydrological system.
Stakeholders' role
The model relies on a multi-stakeholder governance system combining regional and local authorities, water agencies, farmers, researchers, landowners and citizens. This collaborative structure is critical for negotiating water allocation trade-offs, ensuring acceptance of reuse options and embedding solutions into existing water governance frameworks.
Built-in scalable tools
The nature of the approach allows for the gradual expansion of infiltration zones along the river, enabling modular and site-specific replication without major system redesign. Stakeholder and citizen engagement, particularly in water reuse, supports acceptance, reduces conflicts and enables wider uptake across the basin.
Funding pathways
Pilot actions are funded through Horizon Europe, while scaling up is enabled by integrating solutions into regional water management and climate adaptation plans, unlocking access to national and EU funding and supporting long-term investment.
