This case study sought to determine how the potable water network of Cerro Prieto, Peru could be improved. The network as it exists now is branched and operated intermittently, exposing residents to water contamination risks and inconvenience. Using EPANET, it was found that the as-built network can support continuous water service, all points could stay over 10 psi, and the current water consumption rate could be maintained. To keep all points over 20 psi, the height of elevated water tank must be increased 6 feet, and the pump switched on whenever the tank drains. It was also found that almost the entire community would benefit from several possible closed loops in the network, but the high cost gives downstream loops higher priority. Due to the scarcity of water in the region, the first action must be assessing the well capacity, and a water conservation plan that may include water meters.
