| dc.description.abstract | Water is a precious natural resource vital for life, national development and the environment. Groundwater resource supports many urban and rural area of Ethiopia. In Addis Ababa city the shortage of portable water has not yet been solved even if Addis Ababa Water and Sewerage Authority have implemented different mechanism to solve the city‘s problem. This research is conducted in Addis Ababa city at Akaki Phase II groundwater well field located in the south East of Addis. The well field is currently one of the main sources of water supply to Addis Ababa City. The objective of this study is to assess the groundwater management practices of the Akaki Phase II well field and the effect of abstraction of water without proper groundwater monitoring system in place. According to the analysis of the pump test through different methods, the transmissivity and storativity values obtained in this research have great variation from the study report of WWDSE. Among the 15 wells analyzed 10 have underestimated transmissivity whereas the 5 wells are expected to have overestimated transmissivity. The groundwater sources of the Akaki Phase II has wrong assumptions in the design phase since there is not given a major stress to the well drawdown loss by considering either the well efficiency or the effect of partial penetration to the well. From the questionnaire response gathered; the result clearly showed in Akaki Phase II well field that the groundwater monitoring practice is not regular, inconsistent, and focused only on limited visible parameters. If the current monitoring practices continues it will lead to the failure of the wells and unable to meet the objectives of the project. | en_US |
