TOWARDS AN ALTERNATIVE WASTEWATER TREATMENT & USE FOR THE MICROCLIMATE IN KOLFE KERANIYO SUB CITY CONDOMINUM HOUSES, ADDIS ABABA

Major Advisor: Assistant Professor Nada Mohamed Ramadan (Ph.D.)

The idea behind a climatically responsive urban design is vital to any notion of sustainability because it enables living spaces to make better use of natural resources, increases public safety and mobility in outdoor areas. However, due to uncontrolled urbanization and a high proportion of informal settlements, measuring the city's sanitary conditions is challenging. The Akaki Rivers are used as waste disposal sites for a variety of wastes from residential wastewater and human excreta. Currently Akaki Rivers suffers from anthropogenic impacts such as effluent discharge, diversion of its tributaries, pumping of water for irrigation, deforestation, erosion, and town settlement around the rivers. The study's aim is to identify an alternative wastewater treatment and usage scheme for the microclimatic conditions of KK Sub city condominium houses. The study addresses the research questions through an exploratory study of an alternative WWT and usage for the microclimate around condominium houses in KK. The study offers detailed knowledge on the liveability condition of condominium buildings, WW disposal, and architectural terms of microclimatic condition. During the investigation, the procedures of diagnosing the research problem, scanning for possible solutions, and finding a novel concept for how to fix the research problem were covered. The study employs observation of case area, interview with case area condominium residents and AAWSA employees and document reviews for data gathering, as well as images, tables, and charts for data processing and presentation, in order to satisfy the goals and address the research questions. Based on a health, environment, natural resource, technology, finance, economy, community engagement, culture, aesthetic, institutional reinforcement and treatment option of WWT designing aspects, the research findings reveal that there isn't enough wastewater treatment for Kara Kore and Weyra-Sefer condominium houses due to a lack of design considerations and the amount of wastewater generated daily. Furthermore, the study discovers that a wastewater treatment system can be a combination of different systems, resulting in a much safer wastewater treatment, reuse, and release approach.
