How we get our clean water

Ever wondered how we get our clean water?
It starts out with a river. That river has a giant sieve that takes out branches bugs and leaves.
Then coagulant is added this sticks to dirt and makes it heavy, causing it to sink to the bottom.
Next the membrane removes germs from the water.
After that the water goes to the carbon tank.
The carbon tank extracts all the pesticides and organic compounds like tastes and smells.
Finally it goes on to the chlorine tank which kills any remaining viruses and bacteria from the water.
Then it all gets sent away for us to use.
And thats how we get our clean water.
