Modeled Sphere

My business partner Mike Wong made this drawing of an assembled sphere.  This is very close to what a water storage tank will look like.  Concrete blocks, around 3.5 inches thick, sphere about 9 feet in diameter, holds about 2,900 gallons. It is shown with an opening at the top.  Easy to assemble, very strong below ground.    Click on the image to see it better.


  1. Will the water be drinkable? Or will it have to be boiled first? How many gallons will it hold?

  2. It depends on the application. For storing rainwater, water is filtered and treated as it is used. Can be used to store potable water. It holds almost 3,000 gallons.
