Ten years of civil war has set the people of Sierra Leone up against immense challenges. The country is one of the world's poorest, and 43% of the population lacks safe water to drink. Almost 90% don't have access to toilets. One out of every four kids in Sierra Leone dies before their fifth birthday, many from diarrhea, worms or other water-related illnesses.
The hope: these diseases are preventable with clean water sources and good hygiene practices.
