RESUMO

New stormwater control techniques have emerged during last years, trying to mimic and keep the natural conditions of hydrologic cycle. One of these measures, known as storage facility, detains part of the rainfall runoff to release it at controlled rates downstream, attenuating the hydrograph peak and redistributing the volume over a certain period of time. The focus of this report is the detention basin, a storage facility designed to empty out between runoff occurrences. Its insertion and use are discussed through CDHU experiences, based on real cases, where the results show that this new urban drainage control system is still a polemic issue, for what technicians, governments and population are unprepared. Society’s concerns about sustainable and environmentally correct measures, inside which detention pond is placed, are rightful, however its implementation in the course of legal procedures has been made carelessly, unplanned and without considerations of difficulties and impacts. In addition, evaluation of its performance along with regulation of using forms, dimensioning, operation and maintenance are also required. Moreover, sensitiveness, consciousness and education related to detention basin should be improved, since there are paradigms to be broken and obstacles to win. At the end of this report, it is suggested some guidelines to incorporate detention basins in new land development, not only to facilitate and instruct the use of this structure, but also to improve society’s acceptance.
