A water quality analysis of rainwater collected from catchment equipment(2m${ imes}$1m) was conducted to determine its suitability for domestic purposes, in this study. As the results of analysis, the pH of rainwater was 6.3${pm}$0.3, and the turbidity of rainwater was over the 5 times than drinking water guidelines. For the usage of rainwater as the domestic and drinking water, the rainwater is need to treat. The analysis value of BOD was about 3 mg/L and the values of heavy metal as the Pb, Cd, Fe, Mn, Cr$sub$6/$^$+/and Cu was satisfied with drinking guidelines. Overall results of analysis support the possibility of rainwater as the domestic and drinking water.
