I have visited wastewater treatment plants in two of the cities I have lived in and I honestly think such a visit should be required for everyone--young and old--who lives in a house or apartment serviced by a municipal sewer. It is eye opening to see what happens to every drop of water you flush or wash down the drain, and especially to see what kinds of things make it into the wastewater stream and to the treatment plant. The tours are often run by folks who actually work (or have worked) at the plant as operators and are quite knowledgeable at all the processes in play.

This is interesting. Not only giving you exposure to how things work, but also encouraging awareness of things easily taken for granted.
