Análise do índice de perdas no sistema de abastecimento de água na cidade de Delmiro Gouveia - AL

Abstract

The loss control is one of the most important actions to reach operational efficiency and the financial management of a sanitation company. In Delmiro Gouveia, the company responsible for the water supply is the Sanitation Company of Alagoas, that it shows losses as some other water and sanitation company. The great difficulties imposed to this system are the missing of infrastructure in terms of technical monitoring resources and measuring instruments for operational control. Faced with the absence of these tools of losing water, that work had analyzed through of loss indicators: percentage loss index that is the most use and it has easy comprehension; it also relates the total volume lost (real and apparent losses). That work shows an analysis of the water losses index, for the period between 2011 until August of 2017, through the database related to the water supply system and water losses indicator, there were large losses of unbilled water in the system with variations from 643 thousand to 2.18 million m³. The analysis results were represented by interpretative graphics and water balance matrix. In faced of this, considering the necessity of a loss control program implementation, alternatives for the mitigation of water losses are suggested in order to increase the system efficiency.
