1. The pipes go downwards.
2. They get bigger as you go down.
3. Things can get stuck in the pipes.
4. The pipes lead to the sewer, which has moving water.
This led us to wondering where the sewer went with this dirty water, so we referred back to our pictures we suggested the wastewater treatment plant! Since we can't go to the wastewater treatment plant (it's for kids age 12 and up), videos will again have to suffice!

Here are our revised models:
1. The pipes get bigger as they go downwards into the sewer. The sewers are so big people can fit in them with lots of room to spare.
2. The pipes connect with other pipes and...
3. They eventually lead to the sewer, which leads to the waste water treatment facility.
4. The wastewater treatment facility cleans the water by removing really large things like money, animals, plastic bottles and wipes. They use things like bars and screens.
We're wondering the following:
1. How does the water get so dirty in the first place?
2. Besides the bars/screens, are there any other machines that help remove stuff?
3. After the big stuff is removed, the water still looks super gross. How is it cleaned further?
4. Where does the water go after the wastewater treatment facility? Does it go to a body of water? Or another facility?
