Hi fushing
How is your school trip to the waste water plant was it boring
No
It wasn't at home
It was really interesting
Wow
What did you see we saw the plant make dirty water clean again
Really how well first dirty water from our homes goes into the plant
Then special screens remove large pieces of waste from the water
What happens next while large machines remove jerms and other things from the water
These things are usually too small to seep
It takes a few more steps
After that before the water becomes clean again
Wow
I used to think it was easy to get clean water me too
I didn't realize it was so hard
