The World Bank highlights Work in Water and Sanitation at the Water Week,

The Bank and the Water and Sanitation Program (WSP), a global multi-donor partnership, were at World Water Week in Stockholm to highlight successful solutions to the water and sanitation problems facing low-income communities. The World Water Week in Stockholm is an annual event where the international community observes the International Year of Sanitation. Two out of five people worldwide lack access to a toilet. One out of six does not have access to safe drinking water. This lack contributes to two million child deaths a year, reduces school attendance, and is a fundamental deprivation of human dignity. Lack of sanitation pollutes water resources. The costs of environmental and health degradation due to inadequate water and sanitation has been estimated at over 1% of GDP in Colombia, 0.6% in Tunisia, and 1.4% in Bangladesh. The economic costs in Southeast Asia are even higher.
