This contract was for reviewing the Water Supply to Addis Ababa City. Water in Addis Ababa comes from both river-fed reservoirs (notably Gefersa, Legedadi and Dire) and from groundwater (notably the Akaki wellfield). Severe vulnerability of water supply, in terms of both quantity and quality were reported. Indeed, the UN projected water scarcity (i.e. the most stressed category) for Ethiopia in 2025 (UNEP/GRID-Arendal 2002). Current treated water production is about 180,000 m³/day; average consumption by customers with in-plot piped supply is 22 litres per capita per day.
The objective of the Consulting service was to assess the existing water demand and supply in the Addis Ababa city and evaluate different scenarios on the possible combined use of surface and ground water resource uses to ensure a sustainable water supply for the metropolitan city up to the year 2030. The project serves a total population of about 3.5 million persons.
