Lovemydd, Awesome video of WWTP. I work closely with municipal WWTP's. I last toured it with a group of Engineers and Mayor's it made it more interesting listening to the questions that they asked. I would say that the actual operators may have been at the bottom of their class, however, I would say that the individuals higher up or involved with stormwater and engineering are certainly gifted adults.

Last summer, my DS5 designed on paper a wastewater reclamation system for our camping trailer. He has not toured the wwtp before but he already knew about micro-organisims. It was a very thorough draft with grey water and black water seperated systems.
