Water scarcity and wastewater management are two major challenges that affect the ecosystem and the urban environment. In an arid country such as Egypt, wastewater reuse should be encouraged whenever it is safe and economically feasible. There are many methods for wastewater treatment. This research examines the use of constructed wetlands as a sustainable wastewater treatment method in urban communities. The research methodology consists of a theoretical study about water reuse, treatment and constructed wetlands. It then uses the analytical approach, by studying some examples that have used constructed wetlands for wastewater treatment and concluding their benefits to the community.
