Uso de técnicas alternativas para captação, infiltração e reuso de águas: estudo de caso em Cajazeiras (PB)

In recent years the reservoirs of several northeastern states have collapsed, resulting in water rationing and even the state of emergency decree. Even so, some buildings which have already been consolidated in the urban area do not use any form of rainwater for storage or subsequent reuse. Thus, this study proposes the use of alternative techniques for the storage and reuse of water in a building which has already been consolidated in the urban area of semi-arid regions, based upon the perception that certain functions of the compensatory techniques can be applied to areas with high rainfall indices, as well as opposite zones. In order to do so, we carried out a study on the natural aspects of the city and identified sites that enabled the installation of alternative techniques selected by TecAlt 1.0 software, a program used to assist decision making in storm water management. Regarding suggestions for implantation techniques,The results were positive, even for the semiarid conditions, which is the case of the study place . Researchers may carry out future studies on the topic with the purpose of assessing and budgeting the suggested techniques.
