How a water tower works…
You can (almost) always count on having water from your faucets even when the power goes out.
The water in a community is typically pumped using electricity into a water tower where it sits ready to be used. A typical tower can hold abut a days worth of water. The water in the tower relies on gravity to provide us with water pressure.
Even though pipes enter your home from below the water can travel to your upstairs bathroom as long as it is lower than the water level in the water tower (see diagram below). Such a perfect and reliable system!
Build a mini water tower!
We drive by this huge powdery blue water tower on Saturdays now and we have talked about how it works but I though it would be fun to learn about it first hand!
What you need…
- small water or juice bottle
- large juice bottle
- flexible tubing
- binder clip
First make a hole in the cap of the small water bottle (make it smaller than the flexible tube so it won’t drip). Next make a pin sized vent hole in the bottom of the same bottle. Then squeeze the tube into the hole on cap. Clamp the other end of the tube with the binder clip. Make a hole near the bottom of the large juice bottle and feed tubing through. Now you are ready to fill the water bottle (keep a finger over vent hole as you fill)!
Try releasing the clamp at different heights relative to the water level to see when it stops flowing. Use the bowl to catch the water.
Just because water towers provide such an important and basic function doesn’t mean they have to look boring! As a supplement to this project how about designing you own unique water tower! What could it look like? What could it be made out of? How might it be supported? Below are a few unique examples for inspiration…

This looks like a great book for more water related experiments!
Or how about this cool kit that allows you to build air and water powered models?!
Are you in need of a water tower for your Thomas trains?
