How do they work?

Apparently they dig a shaft down to the water table at a higher elevation and then tunnel from there to where they want the water to go.
What is a ruin? We’re running off of “You know it when you see it” at the moment. Ruins should be non-functioning structures of some age, or their function reduced to tourism and the like.
Generally speaking, specific items from a ruin should go to !historyartifacts@lemmy.world
Illustrations of ruins (or their reconstructions) should go to !historyillustrations@lemmy.world
Photos of ruins back when they were functioning should go to !HistoryPorn@lemmy.world
