Potable Water in Africa
780 million people are without access to clean water in Africa.
3.4 million people
die each year from a water related disease. This is equivalent to the population of Los Angeles.
1 out of every 5 deaths
under the age of 5
is due to a water-related disease.
According to the UN, Sub-Saharan Africa loses

per year collecting water; this is the same as a whole year's worth of labor by France's entire labor force.
