Busy pump

The pic shows a quiet period, but I have rarely seen it without a queue.
It is the pump ar the pre school and the parents, friends, neighbours and maybe all the community use it.
The city water is expensive when it's available, and most of the time there is no supply.
The alternative is water from a polluted stream, with that wonderful grey colour!
We have the water tested regularly in the Central hospital and it is perfect.
