Advantages of our All-in-One Vehicles:

  • Faster: By combining all necessary functions in one vehicle, operations are accelerated.
  • Better: Highest precision in inspection and leak testing through state-of-the-art technology.
  • Cheaper: Increased efficiency through the integration of multiple processes reduces overall costs.

What Makes our Vehicles Unique?

All in one: Each vehicle is equipped with the latest technology for:

  • Sewer cleaning
  • Suction and blowing
  • Sewer inspection and documentation
  • Sewer leak testing
  • Sewer locating

    Your advantage: With our all-in-one vehicles, you get a complete solution for all your sewer cleaning and inspection needs, all in a single operation. Trust in Koller’s tailored efficiency – for fast, precise, and cost-efficient handling of your projects. With our combined sewer suction, flushing, inspection, and leak testing vehicles, manhole covers do not need to be opened multiple times. You save on deploying 1-2 people for the sewer TV inspection vehicle and another 1-2 people for the leak testing vehicle – a total of three vehicles and three employees.

Why is this your Advantage?

In the practice of competitors, the following problems often arise:

  • Lack of coordination: The use of multiple vehicles can lead to coordination problems, which can impair the efficiency and quality of the work.
  • Mutual accusations: Mutual blame often arises in case of sloppy execution or misunderstandings between vehicle teams.
  • Time expenditure and environmental impact: The use of multiple vehicles not only increases time expenditure but also burdens the environment through additional fuel consumption and emissions.

Our solution: By combining all necessary functions in a single vehicle, we eliminate these problems. Our all-in-one vehicles offer:

  • Optimized coordination: Everything from a single source, no coordination between different vehicles required.
  • Higher efficiency: Reduced working hours and personnel effort.
  • More environmentally friendly: Minimization of fuel consumption and emissions through the use of only one vehicle.
    Rely on our integrated vehicles and benefit from a smooth, cost-efficient, and environmentally friendly solution.
