The most fundamental step in waste management is quantifying and qualifying the different types of waste being generated. It is important to have a system for the collection and analysis of basic information about wastes. Among the data needed are: the sources of wastes, the quantities of waste generated, their composition and characteristics, the seasonal variations and future trends of generation. Such information forms the basis for the development of appropriate waste management strategies. In fact, data collection and management should be an on-going exercise for monitoring purposes and to enable future and long-term planning and decision-making. The purpose of this research was to determine the generation rate, physical composition and waste management practices of Arada Sub City and to provide information about solid waste management to the Sub-City. The study was carried out by stratified the institutions into four groups: governmental and non governmental office, educational center, bank and insurance, and churches. Moreover, based on each group proportion representative samples were taken randomly from each group. Sorting of the waste was done using hands to separate the waste into respective composition groups: paper, plastic, glasses, textile and leather, rubber, yard waste, metals, inorganic, electronics, special waste, rubber, wood, potentially hazardous waste. The result of the study showed that the solid waste generation rate from institutions in the sub city was 0.033kg, and 0.44 It per employee per day by weight and volume, respectively, while the density was 74.9 kg/m3. The total solid waste per capita per day by weight and volume from domestic, commercial and institutional center were 0.56 and 2.2, respectively. From all composition, paper took the proportion of 79.11 % by weight and 92.92% by volume, respectively. The total solid waste generation rate from the institutions of Arada Sub City was 0.439 tones, which is 1. 7 % of the total.rnThe study also showed that 35 % of the organizations in Arada Sub City practice incinerations at secured place and 11.7% of the institutions practice incineration without secured place. The result revealed that 35 % of the respondents have suggested that there should be private pre collectors to collect the waste from the institutions. And 20 % of respondents havern11rnrecommended that there should be an organization that supplies containers and dispose off the wastes when the containers are filled. The result also depicted that there is great potential in recycling of solid waste from the institutions in Arada Sub City if it is sorted out at the sources. The usefulness of the out comes of this study is to provide information about generation rate physical compositions and management status of solid waste from institutions in Arada Sub City.
