As stated in OECD (2009a), “goals that are set politically and are not matched by real revenue streams result in major financing gaps and unexecuted plans, with the consequence that the poor suffer most through absent or deficient services”. For example, Ethiopia has adopted a Universal Access Programme, which foresees improving access to improved drinking water sources from 22% in 2006 to 98% in 2012, but it is unclear how this policy would be financed. In some cases, donors share responsibility for lack of realism, for instance when they require the use of best available wastewater treatment technologies that may not be affordable if scaled up beyond the project level.
