What is a sewer inspection with a pipe camera?

Sewer inspection - also called pipe-camera inspection or TV camera survey - is the most precise method for assessing the condition of drain lines. A remote-controlled, high-resolution pipe camera travels through the pipe network and delivers uninterrupted video footage of the internal condition. Cracks, offsets, root ingress, corrosion and deposits are located and documented exactly.

For property owners, managers and site managers, sewer inspection is an indispensable instrument. It is the basis for any rehabilitation planning, protects against unexpected follow-on costs and delivers standard-compliant documentation for authorities. Before buying a property, an inspection provides valuable certainty about the actual condition of the sewer network.

Greentech Solutions carries out inspections to SN EN 13508-2 (VSA standard) and produces professional condition reports with damage classification and concrete recommendations. Combining the inspection with subsequent cleaning or rehabilitation enables an efficient, coordinated approach from a single provider.

In the city of Zurich, inspection is in some cases mandatory: for building alterations, ERZ (the city's waste and recycling authority) requires an inspection to SN EN 13508 once the line is older than 30 years. The VSA generally recommends a TV inspection every 10 years for private house connections. Condition classification is carried out to SN EN 13508-2, the VSA standard applicable in Switzerland - our report meets these requirements and is recognised by authorities and planners.

Camera survey, TV inspection, sewer TV: one procedure, many names

Camera survey, TV sewer inspection, sewer-TV investigation, pipe-camera inspection: all of these terms describe exactly the same procedure. A remote-controlled camera travels through the drain line, records the state of the pipe on video without gaps and makes visible what lies beneath the ground - cracks, offsets, root ingress or deposits.

The names differ only by region and provider. "TV" simply refers to the video transmission from inside the pipe, not to television. What matters is not the label but the evaluation: findings are classified to SN EN 13508-2, so the condition report is comparable and usable for authorities, insurers and planners. If you are looking for a camera survey, a sewer-TV investigation or a pipe-camera inspection, you are in the right place.

What does a camera survey in Zurich cost?

The cost depends on three factors: line length (the more running metres, the longer the survey), accessibility of shafts and inspection openings, and any necessary pre-cleaning if the line has to be jetted before the inspection.

Instead of a catalogue price, you receive a written quote before the intervention - all items transparent, no hidden costs, no middleman mark-up.

Häufige Fragen

What is a pipe camera?

A pipe camera (also called a TV camera or sewer camera) is a remote-controlled HD camera that is driven through pipes and sewers and records the internal condition in real time. Pipe-camera inspection and sewer inspection are synonyms for the same procedure.

What is a TV sewer inspection?

In a TV sewer inspection, a remote-controlled HD pipe camera is driven through the drain line. All findings are recorded and analysed digitally. Damage, root ingress, cracks or misalignments can be located precisely, without excavation.

Are camera survey, TV inspection and sewer TV the same thing?

Yes. Camera survey, TV sewer inspection, sewer-TV investigation and pipe-camera inspection all refer to the same procedure: a camera travels through the line, the condition is recorded and classified to SN EN 13508-2. The terms differ only by region and provider.

How much does a sewer inspection cost?

The price depends on line length, pipe diameter and the preparation effort. You receive a written, binding quote before the intervention with all items itemised - no hidden costs. For larger networks we prepare a tailored offer.

How long does an inspection take?

Depending on line length and accessibility, an inspection takes between 1 and 4 hours. The condition report is typically delivered within 1 to 2 working days.

When is a sewer inspection necessary?

An inspection makes sense before buying a property, after events such as flooding, with recurring blockages, before rehabilitation work or as part of a regular maintenance strategy.

How often should we inspect?

The Swiss water association VSA recommends a TV inspection every 10 years for private house connections, and more often for buildings from before 1960. The camera shows to the centimetre where action is needed, and we tell you honestly when nothing needs to be done.

What happens after the inspection?

After the inspection you receive a detailed report. Depending on the findings, we recommend targeted measures such as cleaning, inliner rehabilitation, spraylining or classic pipe rehabilitation - and we support you through the whole process.
