Abstract: Water scarcity remains a pressing issue in East Nusa Tenggara Province, with Ende Regency being one of the most affected areas. Ensuring a consistent water supply, or water continuity, is an ongoing challenge that recurs annually. This study aims to evaluate the existing piping network in Ende Town, which is served by six raw water sources, with the goal of enhancing water continuity and ensuring a 24-hour water supply. A quantitative approach is used in this study, which involves calculating the water demand at each node within the piping network and analyzing the system using the WaterNet application. Currently, the water flow condition in Ende Town fails to meet the ideal standards for continuous flow (1x24 hours) and minimum residual pressure (0.5-1 atm). All pipe networks, except those supplied by the Mata Air Ae Pana source, have residual pressures below zero. To improve the system, adjustments need to be made to the piping network, including increasing the inner diameter of the pipes, installing pressure-reducing valves (PRVs), deactivating certain tanks, enhancing tank capacities, and upgrading pump capacities.
