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