Sustainable water resources management is a challenge for the world, especially developing countries experiencing population growth, which triggers an increase in water demand. This condition harms the stability of water resources for humans and the ecosystem. Water conservation with rainwater harvesting is an adaptation and mitigation effort to these problems, but Indonesia's application is still minim. This study scrutinizes rainwater harvesting by looking at literature review that had applied in various countries and discussed the advantages and challenges of these methods. Besides, to understand people's behaviour intentions, this study uses self-evaluation as the data to be analyzed using an extended theory of planned behaviour model. This study indicates that rainwater harvesting can have a positive impact on water conservation, such as cut down surface water deterioration and mitigate seasonal disasters. These impacts can felt like a whole if those systems are implemented on a wide scale. On the other hand, the extended theory of planned behaviour model shows that 16.4% of the intention to utilize rainwater harvesting with the highest variable is the attitude variable. Recommended approaches for improving attitudes in rainwater harvesting are described in this paper.
