AHS students went to learn about waste water treatment at the John's Creek Environmental Campus;http://www.fultoncountyga.gov/
It is a very environmentally conscious state of the art, water treatment center. All of the treatment is done underground so no bad smells or noise. It also has very beautiful grounds--some HS kids get their prom pics taken there and they have had wedding groups there as well.
Anyway they were the first large water processing plant to use membrane tubes (look like spaghetti) to filter water and these membranes do an amazing job of cleaning.
Students also were told about the waste of using bottled water--that bottled water mostly comes from the tap and that most water bottles are never recycled, and that our tap water is great! The students received reusable water bottles as they left the tour.
