After looking at our sketches/diagrams/blueprints, we came to the consensus that most of the water ns the sewer heads to a building called the wastewater treatment facility. We updated our model to look like this:
Even though ALL the water doesn't go there, we still had lots of questions about this place! We decided it would be in our best interests to go on a field trip there, but due to COVID-19, the plant in our city is closed for tours. They didn't even have a video for us to watch as an alternative, but two other cities did: London and NYC! So we watched them and took a virtual field trip to both of them!
We compared the two facilities and found some similarities and differences, but still didn't really know how they cleaned the water fully!
This made us revisit our investigation ideas and we took a vote! Maybe we could actually make dirty water and try to filter/clean it ourselves. Mrs. Brinza did give us some random supplies before remote learning started...
We're off and running thinking of how we can not only use stuff in our house to make dirty water safely, but how we could use these things to get the water cleaner! Check back soon for all our ideas!
