Caracterização das perdas de água do sistema de abastecimento de Caruaru/PE

Abstract

Water is a finite and essential natural resource for human beings. With the growing demand for water worldwide, the New Sanitation Framework has established guidelines to monitor compliance with water use rules, ensuring the proper management of water resources in the face of the current critical situation of scarcity. The incidence of water losses in supply systems directly influences access to water and harms the quality of service provided by companies. Water losses are subdivided into real and apparent losses. Real losses are physical losses related to the incidence of leaks in distribution networks and water mains. Apparent or commercial losses are related to the efficiency and control of the systems and can be caused by deficiencies in the water metering system, unauthorized consumption, and failures in the commercial register. Therefore, it is essential to monitor these indices to promote the correct management of this resource and guarantee access to water for the entire population, as well as increase the revenue of companies. This study aims to characterize the real and apparent losses of the water supply system in the municipality of Caruaru, Pernambuco, based on data provided by the Companhia Pernambucana de Saneamento - COMPESA and computational tools. The analysis includes general aspects of the municipality and its influence on its supply conditions, together with the evaluation of technical and commercial data provided by COMPESA and pressure measurement data obtained, using tools such as the Water Balance and Geographic Information System (GIS).
