Resumo

The Rio Manso System is essential for supplying water to the Metropolitan Region of Belo Horizonte (RMBH), Minas Gerais State. This system withdraws water from the Manso reservoir and the Paraopeba river, transporting it through an integrated network of pipelines, reservoirs, and pumping stations. This study presents a steady-state hydraulic analysis of a 14 km segment of the Manso distribution network, focusing on the reach between pumping stations EAT-3 and reservoir R-6. A hydraulic model was developed using EPANET software based on publicly available data, including flow rates, pumping pressures and reservoir levels. Five operational scenarios were simulated to assess system performance under varying water surface elevations in key reservoirs. Results indicate that the system can deliver the design flow rates with the current configuration. However, flow rates are highly dependent on the configuration of the pumping system and, most critically, on the water levels in the upstream and downstream reservoirs adjacent to each pumping station. Additionally, flow diversions between CT-4 and R-6 were found to reduce the volume of water reaching reservoirs R-7 and R-6, highlighting the importance of integrated operational planning.
