In addition, benefit values are highly location-specific (depending on the prevalence of water-related diseases or the condition of receiving water bodies, for example) and cannot be easily aggregated. Approximately 10% of the global burden of disease worldwide could be prevented with improvements to water, sanitation and hygiene and better water resource management worldwide. The burden of water-related diseases falls disproportionately on developing countries and particularly on children under five, with 30% of deaths of these children attributable to inadequate access to water and sanitation.
