Rainwater utilization system is consistes of catchment, conveyance, treatment, storage, and delivery. Catchment methods are divided into roof and ground catchments and are directly influenced on rainwater quality. Generally, rainwater from ground catchment does not have good quality, it can not be used for domestic use. However if it can be used for secondary purpose such as watering livestock or gardening or underground injection. Rainwater from roof catchment has high quality, but the first flush has a some contaminants such as dust and other debris. Therefore it is desirable to separate the first flush of rainwater to be used for domestic water. Storage tank size is determined by intensity and frequency of rainfall, water demand and so on. The bigger the storage tank size becomes the higher the utilization rate and construction cost. In this study, to determine the size of rainwater storage tank and first flush separator, characteristics of rainwater such as intensity, frequency, water demand and rainwater quality around Gwangju area were analysed. From the analysis of rainfall characteristics and water demand pattern, the optimum size of rainwater storage tank was 2.0 m3 per 100 m2 of roof catchment area. And, according to water quality analysis of rainwater harvested from roof, the amount of first precipitation to be removed was 1.32 mm.
