Abstract
This study was aimed to make an assessment forthe potential of rainwater harvesting system in Thailand. Bothhydrological performance and economic feasibility were used todevelop the RWH model for Bangkok, the capital city ofThailand. Net present value (NPV) was applied to analyze thecost effectiveness of rainwater harvesting system. To besummarized, the rainwater harvesting can potentially save tapwater consumption in buildings which also gain financial profitdepending on the designated system. In this case study, theinstallation of the RWH system with rainwater tank with thecapacity of 30 m3 was suggested due to the ability to saveapproximately $13,370 with the payback period of 34.8 years. Inaddition, this method can also the demand of tap water resourcefor 46,509 m3. For the buildings with higher tap water demandor higher tap water tariff, installing rainwater harvestingsystem would be strongly recommended for the implementationof rainwater harvesting system. In order to enhance the waterresource management towards sustainability, rainwaterharvesting system should be considered for the building designlater on.
