Abstract
GeJJersa water supply dam is one of the water supply dams of Addis Ababa city. It is located
within the Burayu Town and Walmara Aanoa Administration in the special zone ofOromiyaa
surrounding Finfinnee. Within the catchment areas of this dam there are very high
anthropogenic activities that can aJJect the sustainability of water in the reservoir. Due to
this, the study area is selected to be investigated under the study title "The practices of IWRM
and its stumbling blocks in the catchment area of GeJJersa water supply dam ". The main
objective of this study is to check whether there are integrations or not among the
stakeholders of Geffersa water supply dam and its catchment area toward the practice of
IWRM. It encompasses the specific objectives such as assessing whether IWRM is being
practised or not in the catchment area, identifying the problems that hinder practicing of
IWRM in the catchment area of GeJJersa Water supply dam, recognizing compatible
developmental activities appropriate to the catchment area and proposing alternative policy
recommendation that help to guide implementation of IWRM in the catchment area. The
research was conducted through mixed research method (qualitative and quantitative data
collection methods) i.e. focus group discussion, questionnaires, direct field observation and
document analysis. The relevant data was collected from different population group that
interact within the catchment area. Purposive sampling was used to select head administrator
of relevant sectors of Burayu Town and Walmara Aanaa Administrations, and Addis Ababa
City Water Supply and Sewerage Service Authority and investors in the catchment area.
Systematic sampling was used to select the farmers found in the catchment area. To get the
necessary information about the land use changes ofGafarsaa catchment area startingfrom
prior years of the dam construction for watershed analysis, the top five persons wilh highest
age found around the dam were selected purposively for in-depth interview lIsing semistructured
questions. The urbanized area that is approximately inhabited with 550 HHs was
treated only by taking field observation and through focus group discussion with the
representatives of BTA in order to gather information about the existing storm water control
and sewerage disposal facilities. The relevant data sources were assessed in order to get
information about land uses of the study area and national water resources policy. The
human activities that threaten water in the dam are the land related activities proceeding
within the catchment area such as agriculture, livestock rearing, deforestation, investments,
uncontrolled waste disposal and urbanization. The lIliss uses of lands by the inhabitants of the
catchment area emanate from lack of integration among the stockholders of the GCA. This
shows that there is limited understanding of the concepts of IWRM. Hence, the study
confirmed that the IWRM has not practiced in the catchment area of GWSD. Therefore, the
catchment area of GWSD should have independent management unit in which all the
stockholders should involve in IWRM from planning to implementation.
