This is only loosely related: The population of East Germany has been shrinking for 20 years now (the reunion was 1990), so that several cities face the challenge to manage a controlled dismantling of infrastructure. For example, sewage systems tend to get plugged up if underused, so that a major of a shrinking city told his fellow citizens to flush their WC twice after each use. The alternative would be to move people closer to the center and destruct obsolete sewers, which is very expensive.

Anyway, as it turns out, no one has ever thought about these kinds of problems before :-)

Unfortunately, a decrease of population seems to decrease the attractiveness of the place as well and tends to increase the emigration.
