Third in a series
In a small village in northwest Senegal, residents depend on a treatment plant to clean enough of the nearby muddy river to provide them with potable water.
It takes a whole day for the blue machine with several attached tanks to purify 8,000 liters from the Senegal River near the village of Ndiawdoune Nar. The 8.1 by 5 meter treatment plant can purify enough drinking water for between 800 to 1,600 people.
