Climate change and rapid population growth are global threats that have a great impact in the degradation of water quantity and quality. In order to address this issue, rainwater harvesting is accustomed in most countries. Rainwater harvesting is simple, effective and environmentally sound measure and a positive solution in climate change adaptation strategy. This concept was adapted in Nalseb, Ambassador, Tublay, Benguet. Main water source of the populace is springs however when dry season comes, water scarcity is extremely experienced. Water sources are dried up resulting to water shortage forcing the populace for scheduling and water deliveries. This study aimed to design a sustainable rainwater harvesting system to surmount the locale’s water shortage. Rainwater will be collected through catchment during rainy season and converted for domestic use and irrigation on dry season. Design was mainly based on the Rural Water Supply Design Manual (2012). Digital mapping tools such as QGIS, Google Earth, Google map, GPS essentials were used in the design process. EPANET was used in the analysis of distribution piping system. The designed sustainable rainwater harvesting system is composed of a gravity dam, break tank, storage tanks and distribution pipes. Water treatment was considered for domestic use. Thus, the designed system is recommended to be adopted to sustain the increasing water demand of the sitio. Moreover, this study can be presented to the local government of Tublay, Benguet for further comments for the improvement of the proposed system.
