Urban Infrastructures in Ethiopia: Drainage System

integrated management of assets are among the challenges faced in the
properly functioning of urban drainage system. Lack of proper
maintenance of drainage and its structures is the potential factor that
causes urban flooding in most cities/towns of Ethiopia. The purpose of
this research was to evaluate and quantify the impacts of inadequate
maintenance on the performance of urban drainage system and its
structures. This study was descriptive, designed to obtain the potential
impacts of poor maintenance on the performance of urban
infrastructures. To fulfil the objective of the study, both primary and
secondary data were used. Literature review, questionnaire survey and
field observation were used to collect data for the study. Findings
reveal that the impacts of poor maintenance are: blockage of drainage
channels, urban flooding and pavement distress like potholes, edge
failure, and sediment accumulation. It is recommended that
institutional set up for effective operation and maintenance of drains
should be strengthened, as the transportation of silt and sands to the
drains is high during dry season, drains should be maintained before
the rainy season and there should be a high degree of close
communication and co-ordination between the urban authorities and
town residents for operating and maintaining the various components of the drainage network and sufficient funds in all annual budgets for
carrying out routine maintenance program should be provided by the
concerned bodies of the town. | | Keywords : | | | Blockage, Urban Drainage, Poor Maintenance, Drainage
