Bioretention and reuse of urban runoff water in arid or semi-arid climates: a review.

Urban runoff water is often considered a problem because it is associated with flooding, soil erosion, and aquifer contamination. However, the lack of water in many areas of the world and the country has turned it into a potential source of supply. Consequently, this paper presents a review of the most recent studies that have determined the quality of this type of water around the world, as well as the research that has been conducted to evaluate the feasibility of its reuse. The state of the art of bioretention systems for the treatment of urban runoff water is also presented, as well as some general information about their configuration and effectiveness. Finally, it is presented which adaptations should be carried out to implement these systems in arid or semi-arid zones, which represent most of the national territory.
