Aplicação da tecnologia de medição individualizada de água com telemetria em clube visando a redução das tarifas atribuídas à geração de esgoto

Abstract

With population growth, utilities have less and less control over the use of water and the production and direction of sanitary sewage in the network. Thus, it is very common to observe in the invoices issued by the concessionaires, the application of tariffs considering the calculation of the volume of sewage assigned as 100% of the supply value, that is, indicating that all water consumed is directed to the sewage system. In practice, this does not occur, as there are consumption points asinfiltration into the soil, evaporation or rainwater sewer system, demonstrating the need for quantification and monitoring so that the tariffs applied based on the precision of the volume spent. In this sense, the individualized measurement system (SMI) of water combined with telemetry is a current technique that presents efficiency in the calculation of the volume of water. Therefore, the objective of the work was to apply the SMI together with telemetry in the club Associação Atlética do Banco do Brasil of Recife (AABB). The study was carried out over a period of 4 months, where the survey of supply points that do not generate sewage was carried out, the installation of the SMI, the installation of telemetry, the monitoring and calculation of the discount to be considered in the invoice. After 3 months of evaluating the results, a total volume of 17,85% was found, demonstrating the importance of reducing the rate and controlling consumption.
