  <dc:description>Urbanization along with its impervious structures is the major challenge of urban
centers. The foundation and expansion of Addis Ababa was associated with the rapid
conversion of land from rural to urban uses more than anywhere else in the country. For
the last one hundred twenty years it has been noticed that there is an intensive
conversion of rural land to urban development such as buildings, transportation
networks, recreation areas, reservoirs and others where most of them are impermeable.
This study has investigated the overall environmental challenges of the urban drainage
system. This study has particularly carried out in three sample kebeles (kebele 01/02,
08/15 and 13/14) within Yeka sub-city. These kebeles were selected because of the fact
that they are representative to address the objectives of this study. Deforestation and
pavement of structures are the major problems in the study area. An exploratory and
Descriptive type of research design methods were used to describe and explore the
existing condition of the general urban drainage system and the natural water ways.
Data collection methods were carried out using both primary and secondary data
sources. The secondary data source was only relevant to reinforce the primary data.
The collected data were analyzed with Ms-excel, AutoCAD and ArcGIS. The results
have been presented with known statistical tools.</dc:description>
