DIAGNOSIS OF THE WATER SUPPLY SYSTEM: A CASE STUDY OF THE MUNICIPALITY OF MARABÁ-PA

Abstract

The Water Supply System (SAA) of Marabá-PA, established more than four decades ago, represents the main access to the vital water resource for many local residents. However, it faces significant challenges, such as frequent supply disruptions and rationing measures implemented by the responsible utility. This study aims to investigate the underlying causes of this scenario, identify possible weaknesses in the system and propose appropriate mitigating measures for each of them, with the aim of meeting the needs of the population. In the methodology adopted, official letters were sent and technical visits were made to the facilities of the Sanitation Company of Pará (COSANPA) to collect relevant qualitative and quantitative data. These data were processed using equations analogous to the Continuity Equation, and based on the results obtained, appropriate solution proposals were elaborated. The results revealed the presence of two distinct water supply systems in the city (Marabá Pioneira and Nova Marabá). The analysis showed deficiencies, especially in the collection and distribution network, as well as weaknesses in elevation and reservation. Each of these areas received specific proposals for improvement. In conclusion, it was found that the SAA of Marabá operates on two fronts: one characterized by robust and technologically advanced infrastructures in certain parts of the system, and another marked by fragility resulting from the lack of maintenance or investment in new technologies, the latter being the main responsible for the problems identified in this research.
