How cold did this even get??

I keep staring at this photo someone sent me on Facebook in amazement and confusion:


I’m a little confused as to whether this is from a weep water system slowly running water through the lines to avoid freeze damage between the equipment room and the gantry, or if it actually attempted a wash cycle at like… -20F or something… and just became a giant aesthetically pleasing mass of colorful ice. Either way, it’s beautiful, but not very useful until temperatures rise and possibly a few blown out hoses get changed.
