Sewer video inspection: the business that sells diagnostics.
The complete guide for anyone who wants to start a pipe and sewer camera-inspection company or add inspection to a drain-cleaning business that currently works blind. Four equipment classes for diameters from 8 mm to 10 meters, seven work stages, what a report that can command a higher fee looks like, and where the revenue realistically comes from.
Start with inspection.
It is the key that opens the order.
The drain-cleaning and septic-service market is large and proven: tens of thousands of monthly searches in Romania for sewer interventions. But an operator who works without seeing relies on trial and error, cannot prove anything to the customer, and can only invoice labor. An operator who sees and documents can sell the diagnosis, the repair work, and then the contract.
Evidence changes the price discussion
A customer who sees roots entering through a joint at 14 meters no longer negotiates whether the work is necessary. The discussion shifts from “is it really needed” to “when can it be done.” Same work, different conversation.
Contractors need a document
Inspection at work acceptance, before concreting or handover, is a document that protects the contractor. Demand is predictable, linked to the work schedule, and the ticket is much higher than residential. This is the segment most small companies ignore.
Whoever filmed the network once owns the relationship
A coded report becomes the reference point. The following year, only you can say what changed. This naturally creates the periodic maintenance contract, recurring revenue that turns intervention work into a company.
Entry cost is low, scaling is optional
Of all the businesses in this series, this one has the lowest entry threshold: a push camera and a van. You can test the market with a few thousand euros, then add a crawler robot only when you have the contract that keeps it busy.
Three configurations,
three accessible customer categories.
What distinguishes them is the diameter you can enter, which determines which orders you can accept and which you must refuse. Review the limitations of each level as carefully as the capacity.
Plumber, drain-cleaning company, or septic service that currently works blind and cannot show the customer what was found.
- A push camera cannot inspect the street sewer network, so you are limited to connections and vertical stacks. Larger contracts remain with other operators.
- Without a rotating head, you cannot inspect lateral connections, and the report remains limited and difficult to price at a premium.
- A single operator means you cannot enter a manhole under confined-space rules, so you must refuse part of the work.
Company seeking contracts with contractors and water utilities in addition to on-demand interventions.
- Without prior cleaning, the robot cannot see the pipe walls. You need a partnership with a high-pressure cleaning company or your own cleaning equipment.
- Public contracts require procurement procedures, guarantees, and documentation, so you need a person responsible for tendering.
- A single robot becomes a single point of failure. A breakdown in the middle of a framework contract puts you behind schedule.

- The industrial segment requires qualifications, written procedures, and traceability. Prepare them in advance, not when the first RFQ arrives.
- Missions are infrequent and scheduled, so revenue comes in waves. You need a residential base and contracts to cover empty months.
- ATEX equipment has significantly higher purchase and periodic inspection costs, justified only if you already have the customer.
Five defects
over forty meters.
A typical section between two manholes can hide deposits, roots entering through joints, cracks, leaking connections, and ovalization. Without a camera, all of these are “a problem somewhere.” With a camera and distance measurement, each defect has an exact position, and the customer digs in one place only.
What a mission looks like
from the phone call to the invoice.
The robot is launched from a manhole and travels to the next manhole, recording continuously and displaying distance. The PTZ head rotates to inspect each lateral connection.
The number of wheels and ground clearance determine whether the robot can pass deposits and joint steps without getting stuck. A robot stuck at 30 meters means a lost day and a real risk of losing the equipment.
The camera elevator raises the lens to the pipe axis as diameter increases so the image is not always taken from the flow line.
The measuring laser allows ovality and defect size to be estimated directly from the image, turning an observation into verifiable data.
Diameter determines
which orders you can accept.
There is no single device that covers everything. A videoscope reaches places where nothing else fits, a push camera covers residential work, a crawler robot is the only option for street sewer networks, and a PTZ pole camera inspects manholes and tanks without anyone entering them.
Practical rule: start with the class that covers your dominant orders, then add classes that open new contracts. Each added class brings a type of customer you previously had to refuse.
From one inspection
to a recurring contract.
This is the part most companies miss after buying a camera. Inspection alone is a small ticket. Value appears in the chain: the report justifies the repair, the repair requires acceptance inspection, and documented acceptance opens the periodic contract.
If you do not perform the repair yourself, you need a clear agreement with whoever does. Otherwise, you give away the most valuable information in the entire chain for free.
Residential work keeps the month running.
Contracts build the company.
The four segments behave completely differently. Residential work has high volume, low ticket, and immediate payment, so it covers current expenses. Contractors come according to project schedules, with medium tickets and predictable demand.
Water utilities and municipalities work through framework contracts, with procurement procedures and deferred payment, but with guaranteed volume. Industry and petrochemicals pay the most and require the most: ATEX equipment, procedures, and traceability.
What must be prepared
besides the camera.
This business has no production hall and no heavy machinery. It has a van, sensitive equipment that works in dirty water, and a safety requirement that cannot be bypassed: the sewer manhole is a confined space.
The van
It is your workshop. Fixed racks for drums and camera cases, a 230 V outlet through an inverter, separate space for dirty equipment and clean equipment. A 20.000 EUR camera thrown on top of a shovel in the trunk becomes a 20.000 EUR camera under repair.
Washing and drying
The equipment constantly works in water containing sludge, grease, and hydrogen sulfide. Without washing and drying after every mission, connectors corrode and the traction cable degrades. Five minutes at the end of the day extends equipment life by years.
Confined-space safety
Four-sensor gas detector, fan, tripod with winch and safety harness, plus written procedure and training. This is not an optional expense. It is a condition for working legally for any serious customer.
Power and autonomy
A robot drum consumes much more power than a push camera. Batteries and inverter must be sized for a full working day with reserve because a mission interrupted at 80% must be restarted from zero.
Reporting software
The place where small companies lose the most time. A workflow where video, photos, distance, and defect coding are entered once and exported as a report ready to send makes the difference between two hours and twenty minutes per report.
Critical spare parts in stock
The traction cable, camera head, robot wheels, and seals are the parts most likely to fail. Order them as a list together with the equipment. A missed mission because of a missing seal costs more than the stock.
The customer does not buy the footage.
They buy the document.
The difference between a company that collects two hundred lei per trip and one that signs framework contracts is not the camera. It is the report. And the report is the only part of the business you can improve without buying anything.
Full video with distance
Shown on the image, not noted separately. Without distance, nothing can be located.
Photo for each defect
A clear frame with the reference point visible. The client must understand it without explanations.
Position relative to a manhole
"23,4 m from manhole CM12", not "somewhere in the middle". This is the reference used for digging.
Diameter and material
Concrete, PVC, vitrified clay, asbestos cement. It decides the repair method.
Consistent coding
The same names for the same defects in every report. That is how your reports stay comparable over time.
Conclusion with recommendation
What is done, in what order, with what urgency. This is where the repair quote is born.
Ten mistakes,
one of which can cost a life.
The list comes from configurations we delivered and discussions with companies that corrected mistakes at their own expense. Number three is not rhetorical exaggeration: sewer manholes kill people every year.
You buy the crawler robot before having a contract that will keep it busy. Without a contract, it is the most expensive device used rarely.
You travel to the site without asking whether the pipe has been cleaned, then see nothing and cannot invoice the job.
You enter a manhole without a gas detector and without a second person. Here, the cost of a mistake is not financial.
You deliver a report without distance and without an identifiable reference point, so the customer digs by guesswork and does not call you again.
You do not code defects consistently, so you cannot compare two inspections and lose the argument for a periodic contract.
You choose only one equipment class and reject half the requests because you do not cover the diameter.
You do not wash and dry the equipment after each mission, then wonder why the connectors fail in the second year.
You invoice only the inspection and leave the repair work to someone else without any commission agreement.
You enter the industrial segment without ATEX equipment and written procedures, then lose the customer permanently at the first audit.
You have only one trained person. Their vacation stops the company, and manhole work requires two people anyway.
