A new report from the World Bank, Wastewater: From Waste to Resource, calls for efficiently investing in wastewater and other sanitation infrastructure to achieve public health benefits, improve the environment, and enhance quality of life. Safely managed water, sanitation and hygiene (WASH) services are an essential part of preventing disease and protecting human health during infectious disease outbreaks, including the current COVID-19 pandemic. Right now, 80% of wastewater is released into the environment without adequate treatment.
“At a time when 36% of the world’s population lives in water-scarce regions, wastewater treatment for reuse is part of the solution to water scarcity and pollution problems,” said Jennifer Sara, Global Director, World Bank Water Global Practice. “Once treated, it can be used to replace freshwater for irrigation, industrial processes, or recreational purposes. It can also be used to maintain the environmental flow and by-products from its treatment can generate energy and nutrients.”
