Today big cities become the first aim for people who wants to get a better condition for their economy and half of the population in the world lives in big cities (United Nation Population Fund, 2007). Climate change is a condition where the atmosphere in unstable. It can happen in places that has high population. There are some data to support this research which are primary and secondary data. But data processing, including the processing, statistical and tabular data, and also spatial data processing. The process to find dry area is delineation form based on PDAM pipe and based on types of settlement. So, there are two types of adaptation based on area which are very dry and not dry. The adaptation pattern in regular and irregular settlement at very dry area are minimize the amount of water usage, and hold water. On the other hand, the pattern of adaptation in regular settlement at not dry area are minimize the amount of water usage and also adding bottled water for dish and drink.
