Water supply is one of the most advanced and developing issues. Collecting rainwater from impermeable surfaces by smart city buildings for non-drinking and irrigation purposes is a possible solution. The presence of permeable surfaces as building supports is one of the reasons that causes the level of the city to rise and cause flooding of roads and damage to the town and buildings, which can be called the collection of rainwater in buildings. Smart fixed it. Intelligent buildings can prevent heavy rains and rainwater collection and direct them to the required destinations with the large volume of rainwater management principles. By intelligentizing the rainwater collection system on the roofs, many floods in the city will be prevented. Building smartness is one of the engineering and management methods that can avoid urban floods and minimize the possible risks to the town and buildings because the roof of a significant building in rainwater collection can prevent waterlogging and also supply part of the water needed by the residents of the building by making the water extraction system brighter in collecting running water.

The study is done for assessment of Rooftop Rain Water Harvesting (RRWH) for non potable uses in a humid urban catchment. In this study, an user response survey was conducted, with 390 sample size, in five types of building uses; Residential, Educational, Medical, Institutional and mixed use Commercial, with variable roof sizes and situated in four different zones of KMA, having wide variation in piped water supply. A database of 32 years of daily rainfall data has been analyzed , in order to find out demand for different end uses for various building, supply from roof runoff, demand supply ratio, priority of different socio-economic factors for each type of building using AHP analysis, user’s opinion on choice of end-use using regression analysis and finally developed a DSS model. Analysis also revealed that the highest acceptance of RRWH are in favor of the Medical uses building, the lowest being mix-Commercial building. Further factors like toilet flushing is found to be most pot...
