Analyze the Hydroenergetic Efficiency in Water Supply Systems. The research was carried out in three stages, having as study area the Guanabara sector of SAA Utinga - Bologna, located in the municipality of Ananindeua / PA. Initially, operational and commercial data were obtained in technical documents and field visits were carried out. Then, the data collected were systematized and detailed by unit and
group of units, as recommended by Pereira and Condurú (2014). In the last step, the SWOT matrix was used to analyze the strengths, weaknesses, opportunities and threats to hydroenergy efficiency in the Guanabara sector. In the results it was verified that much of the volume of pumped water is lost in leaks and / or clandestine connections or routed to other areas. It was also verified the great consumption of
electric energy in the CMBs in the peak times of charging, which raises expenses and reduces the hydroenergetic efficiency in the Guanabara sector. With the SWOT analysis, it was possible to observe that, even in the current unfavorable scenario, the SAA Utinga - Bologna - Sector Guanabara can reach adequate hydroenergetic sustainability index, provided that actions are implemented in the internal
environments and the opportunities in the external environment are taken advantage of. In the research it was observed that the detail of the data is important, as well as that the SWOT matrix can be used for the analysis of the hydroenergetic efficiency of water supply systems.
