Diagnóstico e proposta de mitigação das perdas reais em sistemas de distribuição de água – estudo de caso do Siaa Zona Fumageira – Cruz das Almas – BA

Abstract

Access to drinking water in Brazil is a problem faced by a large portion of the population, with many urban centers experiencing serious water supply problems. The country's various water supply systems have operational deficiencies and, currently, the most common way used by concessionaires to measure the efficiency of a SAA is through the water loss rate in the system. Real water losses in a supply system generate significant impacts on the environment, concessionaires and service users. Loss rates are still very high in Brazil, reaching 40% on average, which represents a major challenge for the sanitation sector to overcome. The topic of losses in supply systems has been widely discussed in society and among service providers. In the present work, a bibliographical research was carried out on the main types of losses, focusing mainly on the forms, magnitudes and causes of real losses in a distribution system. In addition to the literature review, the research aimed to analyze the situation of the Integrated Water Supply System in Zona Fumageira, in the municipality of Cruz das Almas and in the district of Sapucaia, guided by data from the concessionaire that manages the system and surveys photographs taken at the time of actual losses. In the end, diagnosing some main problems, measures are proposed to mitigate real losses.
