These reforms have been backed by a significant increase of the budget starting in 2006, when the water sector was included among the priority sectors of the National Strategy for Growth and Reduction of Poverty. The Tanzanian water sector remains heavily dependent on external donors, with 88 per cent of the available funds being provided by external donor organisations. Results have been mixed. For example, a report by Deutsche Gesellschaft für Internationale Zusammenarbeit noted that "despite heavy investments brought in by the World Bank and the European Union, (the utility serving Dar es Salaam) has remained one of the worst performing water entities in Tanzania."
