In the city of Eaton Rapids the water is filtered by going through these three huge blue holding tanks that have rocks and charcoal inside that clean all the debris out of the water. They backwash the tanks twice a week in order to get all the debris that the rocks catch out of the tanks. They clean the water by addding in clorine and another liquid that kills all the bacteria that could be in the water.
Our trip yesterday was really fun. I learned quite a bit about our city water that I never knew before. I didn't even kow where our towns water treatment plant was before yesterday. We learned that there is aroun 1,000,000 gallons of water in the two towers that are in our town, under water there is thousands more gallons. We also learned that there is 34 gallons of pipes throughout our town that our water travels through. If the power went out in our town there would still be water pressure in the city because they have a huge back-up generator and if that fails as well there is another generator that runs off chemical reaction or somehti like that so no matter what our city will always have good water pressure.
They also took us into the lab yesterday and told us a little about how they do lab testigs on the water in our school and at the hospital. They are required to take 6 samples of water throughout our town but they take more just to be sure there is no problems at all in the water system. They take the samples from our school and the hospital, places that there are alot of people drinking the water. They put the samples in a test container and then add some chemicals and put it in an incubator to see if there is any bacteria or anything bad in it. Laslty they told us about the part of their job that they don't like. They exlained that when there is a water main break they have to go repair it, even in the middle of the winter when its freezing outside.
