This is a SINGLE SKIN LOW POLYGON polyvinyl non-potable water container (half-full) with spigot and valve (in fixed position) similar to those found around construction areas. Diffuse and bump maps are included at 512x512 made from photographic reference.

This is also part of volume 5 of my CONSTRUCTION ZONE collection (Search for "Andy Rak Collection").
