Abstract

Increased population growth is linear to the proportional of the need for housing. Amid the difficulty of providing land for housing, the apartment is the option. Clean water supply for apartment needs is a major concern for developers. The increasingly shrinking source of surface water and excessive extraction of ground water is a factor in finding cheap and easily obtained raw water sources. DKI Jakarta with 2500-3000mm of rainfall per year has the potential of rainwater that can be utilized. The Rainwater Harvesting system is used for rainwater collection. The potential of rainwater can be known by analysing hydrological data using annual rainfall. Criteria of water quality for apartments are arranged based on the number of volumes as needed and the result of rainwater laboratory tests. It is known that rainwater can supply around 13,93% clean water needs for a month at December. According to the estimated calculation, the value of savings obtained if applying the rainwater utilization scheme is IDR 3,769.60 per m3.
