Unlike America, European sewers are primarily cleaned by contractors, who bid jobs with a price per foot cleaned. This arrangement means equipment needs to be as cost-efficient as possible. Water is a cost. Time is a cost. Setup is a cost. And of course, downtime is a cost.
Contractors and manufacturers in Europe have optimized their sewer cleaning equipment for these contstraints.
In 1977, Karl Wiedemann introduced the world to his prototype for water recycling. From 1977 to today, Wiedemann has made more than 60 new developments to the industry, all of which were declared worthy of patent protection. His sewer cleaning vehicle, the "SUPER 2000" ( water recovery , the suction hose reel , the combined high-pressure reel on the boom and more), is still groundbreaking due to the effectiveness of its performance, combined with the simplicity of its operation.
