Abstract
Improving existing drinking water supply services in developing countries depends crucially on available
financial resources. Cost recovery rates of these services are typically low, while demand for more reliable
services is high and rapidly growing. Most stated preference based demand studies in the developing world
apply the contingent valuation method and focus on rural areas. This study examines household willingness
to pay for improved water supply services in a choice experiment in an urban area in Ethiopia, a country
with the lowest water supply coverage in Sub-Saharan Africa. The design of the choice experiment allows
estimation of the value of both drinking water supply reliability and safety. The estimated economic values
can be used in policy appraisals of improved supply investment decisions. Despite significant income
constraints, households are willing to pay up to 80 percent extra for improved levels of water supply over
and above their current water bill. Women and households living in the poorest part of the city with the
lowest service levels value the improvement of water quality most. As expected, also averting behavior and
expenditures play an important role.
