844 million people in the world – one in ten – do not have clean water.

2.3 billion people in the world – one in three – do not have a decent toilet.

289,000 children under 5 die each year due to diarrhoeal diseases caused by poor water and sanitation. That’s 800 a day, or 1 child every 2 minutes.

The crisis

Around 289,000 children under five die every year from diarrhoeal diseases caused by poor water and sanitation. That's almost 800 children per day, or one child every two minutes.

42% of healthcare facilities in Africa do not have access to safe water.
(WHO/UNICEF, 2015)
Every minute a newborn baby dies from infection caused by a lack of clean water and an unclean environment. 
(WHO, 2015)

Globally, 31% of schools do not have clean water and 34% lack decent toilets.

Our approach

$28.4 billion of investment is needed every year to reach everyone everywhere with clean water, adequate toilets and good hygiene by 2030.
(World Bank, The costs of meeting the 2030 Sustainable Development Goal targets on drinking water, sanitation and hygiene summary report, 2016)
If everyone everywhere had clean water, the number of diarrhoeal deaths would be cut by 34%.
(Prüss-Ustün A, Bartram J, Clasen T et al. Burden of disease from inadequate water, sanitation and hygiene in low- and middle-income settings: a retrospective analysis of data from 145 countries. Tropical Medicine & International Health. 2014;19(8):894-905. doi:10.1111/tmi.12329)
If everyone everywhere had adequate toilets, the number of diarrhoeal deaths would be cut by 28%.
(Prüss-Ustün A, Bartram J, Clasen T et al. Burden of disease from inadequate water, sanitation and hygiene in low- and middle-income settings: a retrospective analysis of data from 145 countries. Tropical Medicine & International Health. 2014;19(8):894-905. doi:10.1111/tmi.12329.)
If everyone everywhere practised good hygiene, the number of diarrhoeal deaths would be cut by 23%.
(Prüss-Ustün A, Bartram J, Clasen T et al. Burden of disease from inadequate water, sanitation and hygiene in low- and middle-income settings: a retrospective analysis of data from 145 countries. Tropical Medicine & International Health. 2014;19(8):894-905. doi:10.1111/tmi.12329.)
For every $1 invested in water and sanitation, an average of at least $4 is returned in increased productivity. (Sanitation returns $5.50 from $1 and water returns $2 from $1.)
(WHO, Global costs and benefits of drinking-water supply and sanitation interventions to reach the MDG target and universal coverage, 2012)
Hygiene promotion is one of the most cost effective health interventions according to the World Bank.
(Disease Control Priorities, third edition (volume 2): Reproductive, maternal, newborn, and child health, 2016)
Just $30 can provide one person with access to safe water.
