The revolution begins
The invention of the water recycling
and the SUPER 2000
1977
The idea has been around for years: to use the cycle of water and wastewater economically and in an environmentally friendly way and to make work easier for people by using innovative technology.
The solution follows now: The world´s first sewer cleaning vehicle with water recycling:
The SUPER 2000.
At first, the concept was mocked by the competitors but only a few years later other manufacturers also start to develope their own systems.
The next step to efficiency
the SUPER 3000
1996
The new sewer cleaning vehicle SUPER 3000 is presented. The special feature: integrated separation of organic and mineral substances and a new type of emptying: emptying by auger, directly at the place of use into a container.
Karl Wiedemann also develops his own liquid ring pumps particularly for sewer cleaning vehicles.
