Urban Wetland Systems: Green Infrastructure for Sustainable Water ManagementAs cities expand and become densely populated, there is a respectively growing demand for improved sanitary and ecological conditions and a more intelligent way to exploit urban space. Green Infrastructure is a modern
approach to the urban environment and an attractive alternative to traditional infrastructure made of concrete
(grey infrastructure). Adoption of GI could make a more beneficial use of the multiple ecosystems services and could help in impact mitigation. One of the main fields where GI can play an important role is water management, mainly stormwater management and wastewater treatment services. The eco-friendly technology of Constructed Wetlands is an attractive solution with added values to ecosystem services.
