摘要：With rapid urbanization and the advancement of technology,it causes consumption of natural resources in urban areas and global climate change.The most prominent feature of global climate change is that there are sudden and irregular rains in addition to the dry periods.Irregular and sudden precipitation creates negative results especially on hard and impermeable surfaces.Especially in recent years,scenarios where water resources will be exhausted as a result of drought have to be directed towards the positive side.For this reason,the water resources can be taken under protection by accumulating rain waters that exist today against water shortage in the future.In this study,it was aimed to investigate the potential of using the water used by household residents in several residential areas in the city of Trabzon by using rainwater harvesting method on the roofs.In this context,by calculating the average amount of water used by 120 houses,it was determined how much rainwater collected on the roofs met this amount.In addition,the costs of the rainwater collection system and annual water savings were calculated.
