Just a few thoughts.
The water alone will be about 112 pounds per square foot. That means you are going to have to put this tank on some kind of foundation.
This kid has made his model fence out of Plexiglas. So I calculated what the price of Plexiglas to build a fence around a typical 100X50 foot residential lot would be. This is calculated using ½ Plexiglas sheets. It comes to just under $200,000. That does not include end caps or top cover. And as before you will need foundation, side supports and labor for installation. So you might as well double that price and then some.
Sure Plexiglas is not the cheapest building material but whatever the material I doubt this kid is going to get many customers for his product. Whatever the price of his fence it is going to cost at least as much as adding a new room on the dwelling and his fence will not add near as much to the value of a house as a new room.
A few prepers may go for the idea but if they do they will build the thing themselves and he won’t see a dime. And most prepers will just buy a poly water tank and bury it in the yard.
It’s also going to have to stand being filled with water and possibly frozen solid in the winter. Kind of expect it might have something of an algae problem in the summer.
you may mean a Cubic Foot of water ?
which weighs a little over 60 lbs not 112 lbs
Every site I looked at rated weight of water per square foot at about 62 lbs.
