Regular maintenance and sewer inspection with KOLLER reduces the risk of blockages, prevents surprises, and protects against expensive repairs and renewals.

Using modern technology, we remove impurities and contaminants. We inspect your sewer system for damage.

Sewer maintenance, cleaning, and inspection are prerequisites for healthy wastewater and sewer systems. It improves health and thus contributes to the quality of life.

Furthermore, a general, standard-compliant assessment and documentation of the inspection can provide information about the condition of cable lines/empty conduits, water and wastewater pipes, as well as the sewer systems.

An inspection or maintenance/repair can be arranged for wastewater systems ranging from single-family homes to entire residential areas, streets, or even entire cities.

Pipe and sewer inspection using SCAN, AXIAL, and ROTOR swivel-head cameras is a technique that allows us to determine the current condition of your pipeline without excavation. The sewer pipes are navigated with a self-propelled, steerable, high-resolution camera, and scans, recordings, and measurements are taken from inside the pipelines. Based on the evaluations, we determine whether there are defects or damages (cracks, offsets, deformations, contamination, backflow, or root intrusion) in the wastewater system. We inform you whether a renewal or a possible sewer rehabilitation is necessary and what type of rehabilitation measures would be effective.

In summary, it includes:

• Final sewer inspections (new acceptance, warranty, and rehabilitation review)
• Pipe and sewer route determination (e.g., when acquiring a property or after loss or absence of pipe and sewer plans)
• Preventive/control examinations to prevent backflow and blockages
• Detection of odor nuisances
• creation of route and condition reports for lines, pipes, and sewers
• visual inspections for leaks (infiltration, exfiltration)
• Pipe burst, collapse, and damage documentation / Proposal of suitable rehabilitation measures

We are compatible with all geodata formats (Shape, DXF, etc.). For the most common GIS programs like ESRI and QGIS, there are plugins that allow data to be imported directly from the map into our sewer TV inspection program. The sewer network can also be viewed and managed directly within your own GIS application.

Damage can be detected in the early stages, thereby avoiding severe damage and high rehabilitation costs. The procedure is fast and cost-effective compared to potential excavation work for damage localization.
