How many watertight in USA?

Answer 1

How many watertight what in the USA? Watertight is an adjective meaning something built well and tight enough to not permit water inside (or outside). Since we are in agriculture here, I'll stick to that area. Most farmers will have watertight grain storage facilities. Most of at least like to think that we have  mostly watertight houses. We have watertight boxes for storage of important documents and delicate tools, watertight water storage tanks. etc. Word your question a little better and you may get a better answer.
