It isn't that the rich and the wealthy got their water from elsewhere. They invested more than others in design as well as beautification. From the seventh century AD, the city was ruled by dukes (doge). One of the most photographed locations is the Doge Palace. But the tourists taking pictures of the palace don't stop to notice that the pavement on which they stand (right) is part of an elaborate water storage system that supported the pomp and glory of the palace. The tourism brochures don't tell.
