As you will recall, because of the very intermittent water supply, everyone has a storage tank. Most people use their heads and use gravity, and put the tanks on top of their dwellings.
That meant a concrete cistern, a major project including the removal of the collapsed tank and building a strong concrete box to store water (see diagram below).
First, the big blue tank had to be removed, which meant draining it, loosing it from the surrounding dirt, and finally lifting it out, no mean task. This required a half-dozen people, ropes, cables, poles, and everyone yelling in Spanish, telling each other how it should be done.
The water tasted a little like concrete for the first few days, but then settled down to the normal Huancayo-type water flavor.
