> People don't realize how much maintenance sewers need. What can do about it? I think that education is at fault. Most people in big cities does not realize how costly and important are jobs like sewer maintenance, garbage collectors, signal maintenance, gardeners, etc. Without all this work cities will paralyze, the population will get sick or die, transport will stop working. etc. Without that work civilization instead of flourishing with economic growth and technology it literally will crumble into ruin. Cities work because there is an absurdly large amount of people taking care of them. If it was a private endeavor there will be advertisements about their work everywhere. But, as a public service it is almost invisible. That is a shame.
