Nearly one and a half million Somali have been obliged to migrate internally due to a war that started in 2006 and ended officially in 2009. There are still refugee camps where thousands of people are huddled together and need to get water from the wells you have seen on the video.
This water is usually polluted due to the lack of sanitation and insufficient latrines that cause open defecation.
In Somalia, 45% of the population does not have access to safe drinking water.
