Such pools ... and especially the ones that are supported by an inflated collar ... pose a real challenge to the various codes. This is a good example of our technology outgrowing our laws.
As with the NEC, there does exist a "Model Swimming Pool Code."The Uniform Swimming Pool, Spa, and Hot Tub Code", published by IAPMO is adopted by Reno.
While I have not read that specific code (shame on me!), I have read several of it's predecessors. Such codes typically do a much better job of defining pools than the NEC. Our AHJ is of the opinion that "NEC pool rules are for IAPMO pools."
Typical details that codes refer to in determining whether 'pool rules' apply include are:
-Depth. Less than 24" are typically exempt;
-The presence of a permanent structure, including decking, for the pool; and,
-The use. A family's backyard pool is not going to be held to the same standard as the pool at, say, a day camp.
That pool looks to be storable. It appears that assembly and storage of it are no more elaborate than that required of a camping tent. As such, I would consider the pool as an 'appliance.'
This is where things get really fuzzy. As with hot tubs, there are all manner of different classifications- all which impact code application. AFAIK, UL has no standard, or classification, for portable pools .... nor does the code require any such listing.
In practical terms .... I'd really like to see that frame bonded (or encapsulated), and a GFI be integral to that pump's connection.
Also, in practical terms, I can't see any means of enforcing such rules.
