Condições operacionais de reservatórios em sistemas de abastecimento de água indiretos – um estudo de caso no campus de Cruz das Almas (UFRB)

Abstract

Water reservoirs are storage devices used as essential accessories in indirect water supply systems. Despite of their relevance, they must be operated correctly and maintenance and cleaning are carried out periodically, as a way of ensuring health safety of consumers. This work aims to investigate and diagnose the operational conditions of the building and distribution reservoirs in use in the Cruz das Almas campus. To study the problem, initially, a literature review and a reading of the Brazilian standards that govern construction and operation of reservoirs. Afterwards, the reservoir park was inspected and its operational conditions were evaluated. The results show that, during the period studied, not all reservoirs met the standards and recommendations established by NBR 5626/98 (ABNT, 1998). To the adversities encountered translate into various levels of complexity, from simpler, which do not require a lot of labor and resources to be resolved, such as the lack of level controllers, even problems more complex ones that may be the result of design inaccuracies or failures in execution, and even possible wear caused by use and lack of maintenance. Such problems reflect a greater level of difficulty, involving bureaucratic procedures to be resolved, and still requiring greater investments. Given this scenario, the need for interventions to improve the operational and maintenance conditions of these reservoirs, in order to comply with what is recommended by NBR 5626/98 (ABNT, 1998) and the Ordinance of Consolidation N°5, annex XX (BRASIL, 2017).
