Our eight WATERGRID sites
Our five Demonstration sites
At five Demonstration Sites, carefully designed and locally adapted Nature-Based Solutions (NBS) will be implemented to slow, move, and store water. By integrating these new interventions into a smart, monitored network—together with existing NBS—we will establish Smart Water Grids at each site, supported by digital tools for monitoring, maintenance, and decision-making.
Tamar, Devon & Cornwall, United Kingdom
The Region: Atlantic
The Challenge: Enhancing catchment-scale water retention and resilience
The NBS Measures: Ponds/small lakes across the catchment
Learn more
The Upper River Tamar catchment comprises an area of 47,688 ha and lies in southwest England, spanning north-east Cornwall and west Devon. It flows from the river’s source near Morwenstow, close to the Atlantic coast, southwards to Launceston through gently undulating terrain composed primarily of Devonian slate and sandstone formations.
The Upper Tamar catchment is a rural area dominated by livestock farming and pasture.
Averbode Forest & Heath, Belgium
The Region: Continental
The Challenge: Restoring water levels in sandy heathland ecosystems
The NBS Measures: Counteracting historic drainage by weirs and blocking ditches
Learn more
Averbode Bos & Heide consists of a variety of open and closed naturetypes. Fens, heather and graslands alternate with deciduous forests ans former pine plantations. The historical landuse large scale pine forestation has dramatically changed the sight and hydrology of the landscape. Since a few decades, Natuurpunt is working hard to restore the landscape, hydrology and biodiversity of the area.
A rare area of relative peace and quiet, not affected by construction and spatial disorder.
Bioclimatic Park, Slovakia
The Region: Mountain / Pannonian (Continental)
The Challenge: Maximizing natural storage for agricultural drought mitigation
The NBS Measures: Infiltration strips, terraces and terrain depressions
Learn more
It represents a rare biodiversity hotspot in the Rajcanka River basin, combining pastures, orchards, vineyards, wetlands, small water bodies, and a network of nature-based solutions (NBS) designed to restore the water cycle and soil health.
City of Valencia, Spain
The Region: Mediterranean
The Challenge: Integrating urban NBS for sustainable storm-water management
The NBS Measures: Modular sustainable drainage systems in tree pits, storm-water harvesting and treatment for irrigation
Learn more
Spanning 83,000 m2 in the heart of Valencia, Parc Central acts as a critical green lung within a dense urban environment that faces significant runoff risks. As the city’s first large-scale park to utilize advanced Sustainable Urban Drainage Systems (SUDS), it integrates permeable pavements and retention tanks to demonstrate the power of circular water use in Mediterranean cities.
This innovative space balances functional water management with aesthetic beauty, offering visitors an educational glimpse into the future of climate-adaptive urban design.
Qlejjgha dry-valley, Malta
The Region: Mediterranean
The Challenge: Enhancing aquifer recharge in water-scarce island catchments
The NBS Measures: Desilting and rehabilitating dams, habitat renaturation, bank and soil stabilization, infiltration strips
Learn more
Beyond its ecological significance, the site provides a scenic, cool microclimate for visitors, demonstrating how restoring historic water-management infrastructure can revitalize both national biodiversity and community spaces.
Our three Validation sites
To complement this, three Validation Sites will broaden the evidence base by applying the developed protocols and tools across diverse catchment scales, water scarcity levels, governance and management challenges, and socio-economic contexts Together, these sites will pave the way for future replication and catalyse the upscaling of SWGs.
Gelderse Poort, The Netherlands
The Region: Atlantic
The Challenge: Scaling natural floodplains for climate-adaptive water buffering
The NBS Measures: Large-scale water retention schemes, drought-adaptive discharge management, and water quality optimization
Learn more
The area is appointed as ‘Natura 2000’-area (European Nature directive) and as ‘Dutch National Landscape’.
Schwerin Lakeland, Germany
The Region: Continental
The Challenge: Implement a climate-adaptive water buffer for water supply and agriculture
Learn more
Through WATERGRID, we are developing climate-adaptive water buffers designed to store seasonal surpluses, ensuring a reliable water supply for both farming and nature during periods of drought.
Danube Alluvial Zone National Park, Austria
The Region: Continental (Pannonian influence)
The Challenge: Restoring river-floodplain connectivity for groundwater recharge
Learn more
This rare combination of stunning natural scenery and regional productivity makes the site an outstanding recreational space, highlighting the essential balance between ecological preservation and local food security.
