Feild trip

     Eaton Rapids has two types of well filtration. One type is gravel and the other is porous rock. The porous rock takes way longer for water to filter through it, so the water is cleaner. The gravel rock is still effective just not as good as the stone. Eaton rapids has two elevated water tanks, each tank has 1,000,000 gallons of water. We use these tanks to create water pressure which allows use to use fire hydrants and other things. Even though we have two tanks, if we had a bad fire then we would go thruogh the water fast. You experienced how global-thermal heating and cooling works, it uses the water to keep the air temperature at about 52 degrees. In the summer it cools the house by blowing the cool air around, in the winter the inside air is only 52 degrees so it has to heat it less.

I did not go on the feild trip.
