I was driving home from playing golf with Noah yesterday (which was really fun, by the way). He asked, "Dad, what do water towers do?" I thought to myself, "Well, they hold water." I thought I knew that, but really wasn't sure. So, I did what all dads do when they don't know something...I talked about how complicated it was to explain and told him I would try to look up an easier way to describe it on the internet. Then he said, "You don't really know, do you, Dad?" I said, "No, I have no idea." So now that we have established that I didn't understand water towers, I thought maybe other people might not either. So, I will tell you what I found.
Water towers do actually hold water (see I was right). They hold enough water to service a small city's water demand for a day (on average). They exist because people cannot go without water, so an interruption in the pumps that serve the main water supply are not a big deal if the water tower is the backup. Why is it so high? Pressure. With that much water that high in the air, it creates enough pressure to push the water through the pipes to all of the surrounding houses and businesses. Sometimes you will even see small water towers on buildings...they put them on the roof because the pressure from the main city tower may not be enough to drive the water that high to serve the upper floors of the tallest building.
How crazy was that? Now, I will tell Noah what water towers do when he gets up this morning and all will be right with the world because I didn't sustain a knowledge failure for more than 24 hours. It's one of my personal rules...if I don't know an answer to a question, I must find it within 24 hours or ...well I don't know what...but it has to be bad.
That's all I got for today. Boring, yeah...but it saved me from knowledge failure.
