Small islands are often used as a tourism destination evenhough these have limitations of water resources because of their limited storage capacity. In this context, we need efforts to make sustainable water resources in the small island to support the tourism destination purpose. This study aims to estimate the calculating of water resources carrying capacity in Pari Island. The estimation method is the ratio between water availability and water demand. The water reseources availability is done by considering the island area, aquifer thickness, annual rainfall, hydraulic conductivity or soil permeability, and application of rainwater harvesting technology (PAH). The estimation result of the water resources carrying capacity without technological intervention in Pari Island is 2.05. The meaning of this value is safe without quality aspect considering. The quality aspect can be improved by applying PAH technology but yielding water resource carrying capacity of 1.37 and 1.47 (secure conditional) for each existing condition and prediction 25 years ahead respectively. Basen on this study, the recommendation is management of tourists to support the water resources sustainability and has no impact on the survival of the people who live in Pari Island and the island's ecosystem itself.
