Abstract

Considering the importance of water in the functioning of life on earth, and as a limited resource, we see with concern the waste and losses that occurred in public water supply systems. In this sense, this work seeks to evaluate the conditions of supply systems in the municipality of Pombal in the State of Paraiba. Therefore, the analysis of secondary data collected from the National Sanitation Information System (SNIS) was considered, we considered information and rates of losses in distribution, losses in revenue, population served, per capita consumption, and volumes of water produced, consumed and billed in the period 2010 to 2019. The results show that the city has a slow tendency to reduce real and apparent losses, an adequate per capita consumption; trend of increased demand due to population growth, reduction of the volume of water produced and increase in volumes consumed and billed. . Based on the results, it is concluded that: there should be greater investment to accelerate the reduction of losses; efforts to reduce losses are indispensable so as not to have to increase water production in the same proportion; it is not recommended to continue the reduction of per capita consumption so as not to compromise the minimum conditions of hygiene and maintenance of health; and finally, the trend presented by the volumes produced, consumed and billed need to be maintained so that the city's indicators continue to improve and are among the best in the region or country.
