Evaluation and investigation of make wise of buildings in collecting rainwater from rooftops in controlling surface runoff

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
