The research is concerned with designing of Biogas Production System for Condominium andrnstudying its Feasibility by crosschecking field survey and information from literatures. The fieldrnsurvey data support the opinion about the importance of constructing biogas plant forrnCondominium where the average family membersâ€™ number is five with average monthly energyrncost for cooking is Birr 385 per family.rnThe study indicates that at optimum condition 43.2 m3 day of biogas is obtained from thernsubstrate collected from 10 blocks of Condominium. Based on present energy consumption,rn43.2 m3 day biogas fulfills the cooking energy requirement for 43 households. If householdsrnuse biogas instead of kerosene only, it can serve the cooking energy need for 115 households.rnCompressing biogas reduces storage requirements, concentrates energy content and increasesrnpressure to the level needed to overcome resistance to gas flow. As the result of installingrncompressor for this system, 43.2m3 of biogas volume is stored in 7m3 of pressure vessel and thernpressure increased to 11bar from 1.106bar.rnIn this study, it was possible to see that the Biogas System Design for Condominium isrnfinancially as well as economically feasible as the NPV is positive and benefit cost ratio isrngreater than one. As financial analysis shows the 40 households will save annually Birr 121,175rnor Birr 3,029 per family as a result of using biogas instead of other cooking energy sources &rnusing biogas only instead of kerosene, the 115 households save Birr 1,067 per family per annual.rnThis result is obtained if households construct a 96 m3 biogas plant with daily loading 1.5m3 ofrnnight soil in to digester
