Bandung City is plagued by hidrometeorological problem (flood and drought) which is exacerbated by climate change impact. As the result the southern part of Bandung would easily flooded even after a single rain event. Likewise, the rapid expansion of built area in northen Bandung City caused the diminished rainwater infiltration which subsequently caused drought in dry season. Not only drought, the vast impervious surface exacerbates the flood problem. The flood problem is the second most critical problem according to Bandung Citizen after transportation issues (Bappeda Kota Bandung, 2018) To overcome the flood, the municipality launched Biophore program in 2013 arguing that water could infiltrate and run-off would diminishes and thus floods will be reduced. During this period a million biophores were targeted to be developed. Although the community enthusiastically participated in the program, the biophore itself was proven to be ineffective for flood countermeasure (Rianawati, 2015). In addition there has been an ongoing committment to increase the green open space ratio which was hardly to overcome. Nonetheless, there have been two rentention lakes out of seven in planning that serve as flood and drought mitigation measures. Consequently, as previous study has pointed out that the current measures were not enough on top of prolonged implementation of flood measures by the municipality, there should be a measure that could be implemented widely by the community. Rainwater harvesting and infiltration well are simple yet effective technologies that are proven to reduce rainwater runoff as well as increasing the quantity of ground water (Group Raindrops, 1995). Infiltration well itself has been imposed by law in California State, North America, whereas rainwater harvesting have widely implemented in African and Asian countries. As the same measures could be applied in Bandung City, this study aims to analyze the public acceptance behavior toward both applications. We will study the perception of community and municipalities using likert scale questionnaires, covering the dimension of social, economic, institutional, and environment. The statistical data will be modelled using logistic regression and cluster analysis to propose a predictive modelling of Bandung Citizen acceptance behavior. Ultimately, the measures that had been done along with the modelling will be utilised to make recommendations for policy development of water conservation law in Bandung Municipality.
