Breakdown by sub-sectors
Nearly half of the ODA committed to the water sector in 2003-2004 benefited to large water supply and sanitation systems. Water resources policy/administrative management accounted for another quarter, and basic drinking water supply and basic sanitation received 20%. Waste management or water resources protection, only received small amounts.
According to the 2006 Human Development Report, this predominance of large-scale water and sanitation infrastructure indicates a strong urban focus of aid flows to the water sector.
