RE: Colapsed Water TK
riveted tank and seems quite high to not have a wind girder

RE: Colapsed Water TK
..... As is typical in this forum, the OP begins a long wasteful guessing game
I believe that this is a riveted tank, based on its double and triple row of fasteners. The fact that there is no exterior coating or shiny fasteners also leads me to believe this.
This tank may have a vacuum failure, but it does not look like a typical vacuum failure. Most vacuum failures show a collapse that begins near the top of the shell and forms vertical "valleys"
Where is the tank located ? How old is the tank ??? Is there a large operating tank vent ???

I believe that this is a buckling tank failure and may be related to years of internal corrosion at the water/air interface level.
This particular tank should serve as a lesson on the long term advantage of internal and external coatings .... !!!!
Sulfuric acid tanks, which suffer accelerated erosion at this interface, fail in the same way

Here is a picture of a bolted tank:
It is unusual that the 2nd picture shows evidence of numerous leaks while the 1st picture shows none.
If this is a water tank, the corrosion will have been most severe at the water line, so it is possible that may have been caused by vacuum failure. The question is; does the tank have a roof.
Don't think this is tree damage because the extent of damage is too great to have been caused by a single tree.
RE: Colapsed Water TK
No information yet about the roof (there is /there isn´t)
RE: Colapsed Water TK
Usually, vacuum or wind blow-in would be a large area on one side of the tank, not a band around it like that. Usually, seismic buckling would be at the bottom.
Looks like a riveted tank to me. I remember one guy saying the last tank he had seen riveted was in the 1950's (in the US) and it was done that way to match an existing tank. However, that transition could have varied depending on local labor and practices.
