Global return flow ratio

Return flow ratio measures the percent of available water previously used and discharged upstream as wastewater. Higher values indicate higher dependence on treatment plants and potentially lower water quality in areas that lack sufficient treatment infrastructure and policies. Arid areas with low water use are shown in grey, and scored as low stress when calculating aggregated scores.
