ELI5 How do charities such as WaterAid install taps in African villages without any water supply and provide clean drinking water?

How exactly is water brought to the site of the tap/well and how is it sanitised?

Nothing is brought from anywhere.

When they install taps in remote areas, they are drilling wells deep down to access underground water. So that water is just part of the underground water table/aquifer, nothing man made is bringing it there.

And what sanitizes it? Also nothing really. As long as that underground source of water is not contaminated by something, there is no need to treat or sanitize the water, because there is nothing harmful down in the water, all the soil above it has acted like a filter and filtered it out.
