|Abstract:||At the present time climate change is a global agenda, causing water shortage and degradation of the urban environment in northern parts of Ethiopia. Mekelle city suffers from a shortage of potable water and sporadic flooding problems due to lack of Sustainable Rainwater managing strategies. The purpose of this research is to investigate the rain water harvesting design and technologies to provide sustainable strategies for urban rain water collection and management in arid regions using (WSUD) approach. Such mechanisms are believed to be maximizing potable water in residential area of Mekelle and eventually improve the environmental quality of the city. The research model relies on rain water harvesting using three metrics by taking representative case site in the residential areas of Mekelle. These include measuring the annual precipitation to identify the potential of the rainwater harvesting volume, the water requirement for the community and finally analysis of the surface areas to capture rainwater in the case study site. This paper also tries to figure out alternative rain water harvesting mechanism and technologies on the land-based and roof-based rain water harvesting system. In this regards, rain water harvesting structures and implementation mechanism is proposed in two stages. The first phase of the proposal focuses on identification of urban fabric for rain water harvesting and storage within the case area. The second phase is to develop mechanisms to collect rainwater from rooftops and surface from the residential area and to store in neighborhood storage tanks located in selected public spaces. Finally, the research recommended rain water harvesting techniques from the main urban typologies such as buildings, streets, open spaces and parking lots with respect to the WSUD principles as a set of sustainable water management strategies to enhance potable water for the city of Mekelle.|
