The water demand in Ethiopia has increasing from time to time, which implies to increase rnin wastewater. The previous GTP documents address that the plan of per capita water rndemand has increased to address the increasing need. On the other hand, the source of rnwater for Addis Ababa become challenging. Hence, identifying more water source is very rnessential. Among them, the reuse of greywater can be one of the potential sources for somernwater requiring activities such as toilet flushing, gardening, construction etc. rnGreywater reuse and management is a system that is applied as a solution for minimization rnof water usage for toilet flushing and gardening. This research is intended to show the rnconceptual design for greywater reuse and management by taking American Gibi, Addis rnAbaba as a case study. The area is considered as one of the urban renewal areas in Addis rnAbaba, where it is proposed to adopt the installation of greywater system integrated with rnthe building design processes. rnData for the research were collected through observation, in-depth interview with the rngovernmental officers, professionals of Architecture and construction. In addition, the rnresearch also used documents relating to greywater reuse and management studies and rnresearch as an input. rnThe result of the study showed that the amount of greywater produced in the area can fulfillrnthe requirement for toilet flushing and irrigation for low water requiring plants. The rnresearch also showed that the study area has a chance to implement an integrated system rnof greywater reuse since greywater can be eco-friendly, cheap, easy and flexible to use. rnCreating awareness to the users makes the system sustainable. The construction of rngreywater reuse systems should be combined with other techniques based on the available rnspaces. Attention should be given while to align the use of sanitary fixtures and piping rnsystems to the other water supply and drainage networks in order to ease the reuse and rnrecycling of greywater produced in buildings.
