When the WIEDEMANN water recycling technology brought an enormous increase in performance in practice through the continuous cleaning performance on the sewer without interruptions for the filling of freshwater tanks, new operating concepts had to be developed to relieve the operator. At the time, it was particularly exhausting to continuously connect and disconnect the heavy suction hoses and lower and raise them in the shaft. WIEDEMANN quickly found a remedy and developed the suction hose reel. From then on, with the WIEDEMANN patent, it was child's play to raise and lower the heavy hoses easily and quickly in the manhole as often as you wanted at the touch of a button, simply by turning the horizontal reel on the top of the tank.

Today, the invention is an integral part of the market and has long since established itself in terms of appearance. For WIEDEMANN vehicles it was a unique selling point for more than 20 years, which characterized the unique design from afar.

In the WIEDEMANN enviro tec company logo, the depiction of the suction hose reel has been further abstracted. The colour blue with the powerfully curved graphics also includes the themes of water and movement and embodies reliability, durability, sustainability, but also flexibility, power and dynamism. The representation in the core with the analogy of yin and yang symbolizes the principles of balance, the mutual relation of all existence to each other and stands for the long-term, solid corporate policy, geared towards social, ecological and economic responsibility and mutually respectful business practices.
