What happens when the water tanks run low

So, occasionally, our water tanks run low and all the sediment rushes into our sinks and toilets. This is what it looks like:

Nile Sand hand-exfoliation treatment, anyone?

Its not what you think, it is in fact sand straight from  the Nile, via a water truck, via our water tank.

These are the tanks that we get our water from in Juba. The water is taken straight from the Nile River without any filtration or treatment processes. On the compound we let the water settle in one tank before we pump it into a second tank and add water treatment. We also then filter the water using filters in the guest house and office.
