3 demonstrators created during the project in France, Spain and Portugal. These sites will be the result of the NB-Woll (Water-Oriented Living Labs) strategy aimed at finding the best combination of demand and innovation with the help of 3 Woll (platform). Its design will be based on water demand (quality/quantity), context (uses, locations, stakeholder sensitivity) and regulations. These demonstrators will be adopted by the 3 local authorities responsible for public procurement.
