    Exploring the Challenges of Rural Water Supply Management Systems: The Case of Guto Gida District in East Wollega Zone of Oromia Region, Ethiopia
    (Addis Ababa University, 2014-05) Desalegn, Getachew; Bedri, Abdulhamid (PhD)
    The study Ivas conducted 10 explore the cha llenges of rural water supply management syslelll in Cuto Cida District, East Wollega zone. To this effect, an attempt was made to assess the fu nctiona lity of the existence water supp ly sc hemes of the distr ict; to investigate the inst itut ional supports for the district's schemes; to exam ine the management system of the district's schemes. To this end, the necessary data f or the study was gathered using questionnaire, focus group di scussion, key informant interview and personal observation. During the study, schemes in the study area (Dune Kane and Cari kebele) were observed, and interview Ivith five key iriformants and group discussions with three different groups (water and energy office of Cuto Cida district, water commillee and kebele representatives) were made. In addition, one hundred and seventy four sample households and sixty eight people at community level (water commillee, kebele cabinets, women and youth associations) completed the questionnaires. For household survey, two kebeles (Dune Kane and Cari) were selected randomly and sample respondents were selected using systematic. random sampling, and for questionnaire to be responded by people at community level, the respondents were selected purposefUlly. The data ji-om both questionnaires were analyzed separately, but the data collected ji-om key informant interview, focus group discussion and field observation were analyzed with cross reference of the questionnaires. In addition, the data collected through the aforementioned tools were analyzed quantitatively and qualitatively. The findings ji-om the study indicate that the major challenges for the rural water supply and management are poor service from existing schemes because of construction quality of the schemes, lack of protection, handling problem of beneficiaries and problem of budget allocation for schemes development and maintenance, giving emphasis to supply oriented approach by ignoring how to manage the existing schemes, unsafe drinking water ji-om the schemes; lack of education or training for the community on how to manage or care for the schemes, number of beneficiaries of schemes and low capacity of the schemes, weak community management, no community involvement to select the type of technology to be installed, wasting much time at the water point to fetch water, no established water committee f or most of the schemes, negligible water payment system because of lack of responsible body to organize, lack of man power with relevance of field of studies, logistic problem and poor communication among the district water and energy office, kebele representatives, water commillees and the beneficiaries. At the end, some important conclusions and recommendations have been put based on the findings of the study.

    Investigation on Storm Drainage Problem of Addis Ababa (Case Study at Gotera – Wollo Sefer, Saris - Gotera And Ring Road)
    (Addis Ababa University, 2011-07) Desalegn, Getachew; Yilma, Seleshi (PhD)
    Proper drainage system is required in developing urban areas. In Addis Ababa, drainage problem become an issue during rainy season. This study deals with investigation of storm drainage problem of Addis Ababa and a possible mitigation measure to overcome the problem. Despite there are many places in the city facing storm drainage problem; Ethio china road (Gotera – Wollo sefer), Saris Gotera road (Debrezeit road) and Ring roads are areas selected for this study. Based on primary and secondary data collected, the problems in the areas are categorized as construction, management and design problem. The method used to investigate management problem is direct field data collection and site visit but the construction problem is analyzed using field survey as well as comparison of design with what is implemented in the ground. Design of the study area is evaluated by redesigning of the system using the computation sheet used in American Federal Highway Administration (FHWA) urban drainage design manual and Addis Ababa City Road Authority (AACRA) urban drainage design manual with some modification. Design of storm drainage system evaluated in this research includes inlet spacing, pipe sizing and inlet type selection. The Values of inlet spacing and pipe sizing obtained by redesigning is compared with the original design. The result of this paper shows that the problem in Gotera - Wollo Sefer and Ring road is caused by insufficient drainage operation, over spaced inlet spacing and minimum pipe size is used. The investigation in Saris – Gotera road also shows; the curb inlets are over spaced and constructed with very small opening, the operation system of the drainage is in sufficient and curbs are not constructed according to the design.Finally, based on the result obtained a possible mitigation measures is recommended.
