We went to the Waste Water Treatment Plant. IT STUNK REALLY BADLY! Our guide's were Ms. Drizzle and Sprinkle. We saw what water look's like when it's done going through pipe's. EWWWWW! It was SO gross! We also saw how they made this type of fuel. They BURN waste in a big oven like thing. IT SMELT THE WORST OUT OF THE WHOLE ENTIRE TRIP! We even saw crow's DRINKING the dirty water that wasn't cleaned yet!
