Nature Based Smart Water Grids for Integrated water and drought management
Abstact:
WATERGRID’s objective is to develop and demonstrate the Smart Water Grid (SWG) concept for more climate resilient water management, particularly targeting extreme drought, but framed within Integrated Catchment Management, addressing the whole catchment in a holistic approach.
The resource efficiency of Nature Based Solutions (NBS) previously established in eight sites will be analysed alongside the academic literature, forming an Evidence portfolio (Project Result 1 – PR1). Of these eight sites, five will be demonstrators, spread across the Atlantic, Continental, Mountain and Mediterranean biogeographical areas, with specific water scarcity challenges, NBS types and scales, in which 58 additional innovative and locally attuned NBS will be implemented to slow, move and actively store water for reuse as part of locally designed SWGs.
Three validation sites will mainstream potential of the SWG approach and demonstrate replicability of the Project Results (PRs) that have been co-created and co-deployed with 138 stakeholders in a participatory approach.
Protocols and standards will be developed, providing a step-by-step guide for the design, maintenance and operation of the SWG (PR2). A digital Platform (PR3) will display models of the catchment and a Design App will provide guidance to users on designing NBS into their SWGs.
This Platform will be linked to a Monitoring programme (PR4) to display real time information via a Digital Twin to support long term maintenance of SWGs. An Operationalising toolkit (PR5) will create enabling social, governance and economic environments for sustainable SWGs.
Finally, at least three Policy briefs (PR6) will display SWG benefits to various policies, from the EU to the local scale.
By 2035, WATERGRID expects to increase by 20% the water available for usage to compensate scarcity, decreasing 7 types of water pollutants and saving 10.6M €/year through 37 SWGs across Europe.
Leitat’s role in the project:
Leitat’s role will be to coordinate the Spanish validation site, in Valencia, where, together with local stakeholders, a series of NBS already present in the urban environment (Sustainable Urban Drainage Systems, SUDS) and peri-urban environment (constructed wetland of Tancat de Milia) will be monitored. Based on the data obtained, new urban NBS will be integrated into the SWG at tree pits, as well as a regenerated water retention system in the rice fields of the Albufera during the dry season of the cycle.
