More than a quarter of the world’s population lacks access to safe drinking water. In many countries, the existing water infrastructure provides neither comprehensive sanitation services nor adequate wastewater treatment. With the COVID-19 pandemic still challenging public health services around the world, and regional ecosystems threatened by polluted wastewater, financing the expansion of water infrastructure is more important than ever. Water service improvements are complex and expensive. IFC works with clients in emerging markets to build innovative, market-oriented and long-term solutions to water infrastructure challenges.
