The water security of the São Paulo Metropolitan Region (RMSP) has historically been addressed through the use of hard engineering-based structures, involving the implementation of conduits and detention reservoirs, colloquially known as "piscinões". Despite playing a significant role in attenuating peak flow rates, Brazilian detention reservoirs have little to no effect on water quality. Currently, the São Paulo Metropolitan Region boasts 53 such reservoirs, totaling a buffering volume of 9.95 million m³. Most of Brazilian municipalities have yet to achieve universal access to sewage collection and treatment services, and thus, the load received by the drainage system from this source remains significant. Furthermore, due to the absence of a diffuse load control system, detention reservoirs accumulate large quantities of pollutants during their operation. In 2019 alone, the São Paulo City Hall removed 170 tons of pollutants from the city's reservoirs. Moreover, these reservoirs are in fact used only during the rainy months, remaining largely unused for the rest of the year. The initial design of these structures anticipated the implementation of recreational facilities within them, which could be utilized during the dry season. However, due to the context of water degradation, such use is rendered unfeasible. Therefore, the adoption of new strategies that render these reservoirs multifunctional, allowing their use beyond quantitative water control, is necessary. This study presents strategies for converting detention reservoirs into stormwater treatment units through Nature-Based Solutions and integrating these structures into the urban landscape, using techniques that are well-established in international references and suitable for the Brazilian context. Thus, it aims to contribute to the development of cities that are more adapted and resilient to climate change.
