Cleaning the water in Yiganda

This is what happens to the water from Lake Tana in Yiganda when stored for a while.
The kebele chief added some chemical to bring the dirty particles together quickly and the particles gathered and settled at the bottom.
Once the dirty part settles inside their jerrican or clay pots, the community carefully takes the cleaner looking top part to another container and uses it.
However, not everyone afford the chemical and the cleaning-with-time process can take a day or so. Yiganda, Zege, Bahir Dar, Amhara.
