The situation of relative water scarcity becomes a classic problem in developing countries. This issue is not about the absence of water, but rather about the inequality with regard to access to water. Scarcity of water is a part of daily life for some though the area of abundant water resources. The factors that lead to this exclusion of water are described by applying political ecology of hydro-social cycle. The concurrent transformative method is used in this research to obtain deeper understanding and to generalize the situation. This research formulated four factors that influence to inequality access to water beside hydrological factor. The factors are lack of planning, collusion, lack of information transparency, and inconsistency of water regulation. All factors can be eliminated by improving water regulation, monitoring, and implementation. In doing so, the benefit of water can be equal to all users.
