Abstract: The inventive technology may include several independent inventive aspects relating to: attachment componentry and associated supports (such as flanges) that are used to create a tight, vandal resistant seal between adjacent panels of a fluid containment apparatus, and facilitate assembly of panels to form such apparatus, and facilitate disassembly thereof; strategic location of crane hook attachment components so as to avoid unwanted misorientation of a panel suspended at such components during containment apparatus construction; attachment componentry that include angled driven pin axes or provision of automatically self-seating upon pin driving of, e.g., protrusions in proper positions in corresponding apertures, where such proper positions may coincide with proper, tight sealing relative positions of adjacent, attached panels and enhance installed apparatus stability.
