Abstract Gerbangkertasusila (GKS) Metropolitan Area is a strategic area with an urban nature that has a very fast economic, physical, and demographic acceleration. This rapid development has caused pressure on the environment, and has caused the depletion of natural resources, especially water resources. Water resources are the most important natural resources and are related to a series of ecosystem services such as flood management, water purification, recreation and especially water supply. Water supply can be assessed from a supply and demand perspective. In Indonesia, the process of calculating the carrying capacity of water is calculated spatially using the scale grid system method. The use of this method aims to reduce the limitations of data that has different scales, to facilitate the process of merging or aggregating data to get more in-depth results. Therefore, it is interesting to use this method to assess the status of water carrying capacity in the GKS Area, given the importance of the GKS role on a local and regional scale in East Java Province. In addition, this method is relatively new, so there are not many cities in Indonesia that apply this method to assess water carrying capacity.
