Globally, 58 percent of wastewater flow generated by households was safely treated in 2022. There are considerable disparities in wastewater treatment worldwide between countries. For instance, 100 percent of household wastewater flow is treated safely in the Netherlands, but less than 25 percent is treated safely in countries like India, Russia, or the Democratic Republic of the Congo (DRC).
