Abstract

Ensuring sustainable water supply remains a critical environmental and engineering challenge, particularly in vulnerable rural communities. This study evaluates the hydraulic performance and environmental efficiency of the existing water distribution system in Barangay San Alonzo, Balingoan, Misamis Oriental, using WaterGEMS software. Single-period and extended-period simulations were conducted to assess flow distribution, pressure losses, and network reliability under varying demand conditions from 2018 to 2037. Model validation was achieved through convergence testing, the Wilcoxon signed-rank test, and the Friedman test to ensure stability and statistical consistency. Results indicate that the current system cannot sustain projected water demand over the next two decades, primarily due to population growth, limited source capacity, and infrastructure aging. The study recommends network rehabilitation, pipe resizing, and integration of solar-powered pumping systems to enhance environmental performance and energy efficiency. The proposed model supports sustainable water resource management and can serve as a reference for other developing regions facing similar challenges.
