dc.description.abstractClimate change is the sever problem that the whole world facing today. It is now widely accepted that climate change is already happening and further change is inevitable. Water supply source of Addis Ababa Metropolitan Area is presently from two sources namely surface water and ground water. Sanitation or wastewater management of Addis Ababa is currently one Sewers WWTP and other Dry bed take from vacuum tracks. It has been c clearly seen that climate change has huge influence to impose on the water availability of the water source and WWTP treatment time schedule of Addis Ababa by seasonal shifts of rainfall patterns and magnitude and temperature increase. The main objective of this research is reassessment of current and future water supply and demand gap, wastewater management and their additional management options and evaluation of climate change effect on water supply source, demands and wastewater management. Increase in the number of hot days. Although highly variable, on average Addis Ababa experiences No one day per year above 30-390C. This average frequency is expected to increase to 10-17 days by 2030 and 40-50 days by 2090. In this case water demand of a city increased dramatically and Increased CH4 release from WWTP to atmosphere and increase an amount of a GHG in the atmosphere and potential source of water supply more of did not affect by the climate change. In Legedadi catchment the future surface runoff at both time horizons shows a slight increment in both time horizon by scoring 2.7% and 1.4 % increase in 2030’s and 2090’ time horizon respectively. In dire catchment case the surface water potential decreases by 2.5% and 9.2% respectively in 2030’s and 2090’s.Gefersa shows a higher increase in surface runoff in both time horizons by showing 6.6% 5.4% increase in 2030’s and 2090’s time horizons respectively. The water conservation, demand management and wastewater management analysis used the Vensim ® DSS and developed water conservation, demand management and wastewater management program expands the current program to further enhance water conservation and wastewater management into the future.en
