INSPECTIONS
With our high-resolution camera inspection systems, we conduct standard-compliant condition and damage analyses on drainage pipes and sewers of all nominal diameters – from connection lines to walk-in main sewers.
CLEANING
Our advantage in sewer cleaning lies in two independently driven pump systems – a powerful sewer flushing pump and a high-pressure pump – thereby ensuring maximum efficiency and the highest flexibility in operation.
REHABILITATION
Whether it’s manhole rehabilitation, pipe rehabilitation, or well rehabilitation – we are your competent partner for professional, economical, and sustainable rehabilitation solutions.
Our aim is permanent repair with maximum operational safety, long-term value retention of the systems, and minimal disruption to the existing infrastructure. Thanks to our many years of practical experience, we guarantee efficient, timely, and high-quality execution – even under demanding operating conditions.
LOCATING
Whether it’s cable fault and cable break location, line location, pipe or manhole location, recording sewer routes, or localizing buried containers.
We make the invisible visible!
Using state-of-the-art location and measurement technology, we record underground infrastructures
COMPANY
Our expertise comes from practice – we know what matters on site. For over 50 years, Koller Kanalräumung GmbH has been developing and building powerful and energy-efficient special vehicles, with which we consistently deliver peak performance even under the most challenging conditions.
CONTACT
We are not a classic emergency service, but we are available quickly and reliably for urgent needs or in exceptional situations. Thanks to our readiness and flexible organization, we react promptly and solution-oriented.
Quick to deploy – only emergency services are faster.
Koller Sewer Cleaning GmbH
We are among the few specialists who still develop and are responsible for their own innovations, prototypes, equipment, and vehicle superstructures.
Development, construction, operation, maintenance, and repair – entirely in-house.
As senior and junior partners, we jointly manage our GmbH and personally stand for development, implementation, and quality. What we promise, we deliver ourselves – from the first conversation to the completed assignment. Our responsibility does not end with the signature – it begins right there.
In compliance with all legal regulations, each of our high-end vehicles and special work equipment is custom-built by Koller Sonderfahrzeugbau – as a tailor-made solution for its specific purpose. From the fully electric 2.5-ton compact vehicle to the volume and weight-optimized 44-ton special superstructure, every system is technically thought out in detail, fully equipped, and uncompromisingly designed for maximum performance.
Our particular strength lies in technically demanding special operations: pipe and sewer inspections with standard-compliant documentation, ultra-high-pressure water cleaning work, and wet and dry vacuuming at industrial levels.
For over 50 years, Koller Kanalräumung GmbH has relied on powerful, energy-efficient technology, with which we consistently deliver peak performance even under the most difficult conditions.
Our expertise comes from practice. We know what matters on site and have aligned our entire operation precisely with these requirements – technically sophisticated, organizationally efficient, and always ready for action.
Our roots trace back to 1582 – to the agricultural ancestral home known as Petritsch. Over 100 years ago, Josef Koller began waste and sewer cleaning, laying the foundation for our current business. A Tatra T 30 from 1929 is still preserved and in use today – a sign of living continuity and technical sustainability.
Today, we lead the company in its third and fourth generations, representing technical leadership, practical experience, and uncompromising quality in the sewer cleaning and vehicle construction industries.
Koller is not cheap – but it offers good value.
With our sophisticated 5-in-1 vehicle concepts, we combine high and ultra-high-pressure technology, sewer inspection, line location, and wet and dry vacuuming technology in a compact two-person system. This stands for maximum efficiency, reduced deployment times, and highest cost-effectiveness.
When you need us, we are there. Around the clock. We are not an emergency service, but we are available quickly and reliably for urgent needs or in exceptional situations.
Quick to deploy – only emergency services are faster.
