Análise do processo de implantação de reservatórios para aproveitamento de águas pluviais na cidade do Recife, Pernambuco

Abstract

As the population grows, it increases the search for drinking water and the use of alternative sources of abstraction becomes necessary, since surface and groundwater sources are no longer suppressed as population assessments. As alternatives to meet these needs, rainwater reuse can be reduced, mainly because it is an affordable water resource. In this context, this research aimed to analyze the process of implementation of rainwater reservoirs in the city of Recife, based on Ordinary Law No. 18,112, 2015. Data on the quantity of reservoirs built in the city, their uses and dimensions available from EMLURB (Urban Cleaning and Maintenance Company). The identification of the advantages and difficulties of the implementation of rainwater reservoirs was verified through the application of questionnaires to the technicians and engineers of EMLURB and SELURB (Executive Secretariat of Licensing and Urbanism) and interviews with professionals, engineers and technicians of water techniques. teaching for keeping the law. Based on the results, there was a growing demand for the construction of rainwater reservoirs in the city of Recife since the law's inception. There was a 98% increase in relation to construction before the law was observed. It was still possible to identify or think in part of those responsible for enforcing the law and who complies with it, since both sides relate to the greatest advantage in reservoir construction and use that are purely economic. Retardation reservoirs also have social and environmental advantages, acting as a mechanism to prevent flooding, flooding, soil destruction, economic and psychological problems for reefs.
