This paper aims to analyze the effectiveness of rainwater harvesting facility, applied in the University of Lampung, in order to promote rainwater harvesting as an alternative of freshwater source for public sanitation in Indonesian regions. Simulation is undertaken in order to investigate the supporting capacity of rainwater harvesting facility toward sanitation freshwater supply in the area of study. 365 days of rainfall data of the normal hydrological year has been used to simulate the operational of the facility which consists of 65 m2 rooftop catchment and 32 m3 storages when supplying sanitation freshwater for about 600 people in the area. The simulation result showed that supporting capacity of rainwater harvesting facility is quite significant. By using rainwater harvesting facility, the taking of groundwater for sanitation water supply in the area can be reduced about 62%. The quality of rainwater stored also has good quality the application of nylon filter and activated carbon filter. Physically, there is no taste, color, and smell from the water. Result of the research indicated that the application of rainwater harvesting can be good alternative of freshwater source for public sanitation on other communal places such as schools, office areas, and business areas in Indonesia.
