Some years ago there was a HN link about people in ancient Mesopotamia (all the way up to about 1100 AD, iirc) that had a sophisticated network of canal tunnels, and they had people that would hold their breath and swim down and repair them. This is a sort of modern version of that... Sadly, I have no idea how to find the link, it was interesting.
