Möbius water engineering (Moebius) - The company is, as far as I know,
located in Hamburg’s south eastern part. Its business is water engineering.
It is a white flag with a celestial blue tressure. A diamond of the same
colour containing a white capital “M” is in the centre. The diamond touches
the tressure at top and bottom.
Source: I spotted this flag on 23 July 2007 near Stade on the river
Elbe..
