Sewer lateral inspection robot: the satellite camera launches from the main, with no digging and no property access

The crawler drives along the main, stops at the connection and pushes a small pan-tilt camera into it. The building's lateral is inspected without opening the road or entering the property.

An operator lowers the Envirosight ROVVER X SAT II crawler into a sewer manhole in a residential street, next to the inspection vehicle.

IN BRIEF

Updated

  1. A sewer lateral inspection robot is a crawler with a satellite camera that drives in the public main and launches a second camera into the service connections of houses and buildings.

  2. The iPEK ROVION SAT II travels in mains from DN150 to DN2000, passes accesses of 12.5 in (about 320 mm) and pushes its camera up to 45 m into the lateral, according to its manufacturer.

  3. Robot Distribution selects the right system for your network, delivers it, trains your operators and maintains it, to buy, rent or as RaaS.

WHY

Sewer lateral inspection with a satellite camera

Laterals connect each house or building to the public sewer. Small, bent and often old, they are where roots, infiltration, intruding connections and cross-connections between storm and foul water are looked for.

Inspecting them from the property needs access to the owner's premises and a reachable inspection chamber, which are often missing. The lateral launch crawler works from the public network: it locates each junction, inspects the lateral and records it in the same report as the main.

HOW IT RUNS

How a lateral is inspected.

  1. Mainline inspection

    The crawler runs along the main and finds the junctions. The Envirosight ROVVER X SAT II drives up to 300 m in mains of 6 to 80 in, at about 30 m/min, according to its manufacturer.

  2. Positioning at the junction

    The operator stops the crawler at the connection, turns the launch head and aims the camera at the lateral opening.

  3. Launching the satellite camera

    The camera is pushed into the lateral, through the bends, filming the pipe. On the iPEK ROVION SAT II, the PTP50 pan-tilt camera passes 90° bends from DN75, on a 45 m push rod, according to its manufacturer.

  4. Report per lateral

    Each lateral is linked to its position on the main, with coded observations and images, to guide rehabilitation, lining or compliance checks.

Inside a sewer main, the Envirosight ROVVER X SAT II crawler launches its satellite camera into a house lateral.
At the junction, the crawler pushes its camera into the lateral.
A technician watches on screen the footage of a lateral filmed by the Envirosight ROVVER X SAT II, in the vehicle control room.
The operator follows and codes the inspection from the vehicle.

BEFORE INSTALLING

What the site survey checks before purchase.

  1. Diameters and bends

    Main and lateral diameters, bends, changes of material and past rehabilitation decide the system.

  2. Manhole access

    The satellite crawler must fit through the manhole: both lateral launch systems in our catalogue pass accesses of 12.5 in (about 320 mm), according to their manufacturers.

  3. Number of junctions

    The number of laterals per section and their length guide the choice between a satellite crawler and a mainline-only crawler such as the CUES Steerable Pipe Ranger II, which works in 7 to 72 in pipes with up to 2,000 ft (610 m) of cable, according to its manufacturer.

  4. Network condition

    Deposits, roots and water level are noted: cleaning first improves the image and makes launching easier.

RULES AND STANDARDS

The rules behind sewer lateral inspection in France

Lateral surveys feed legal duties on network diagnosis and on the compliance of each building connection.

  1. The network diagnosis must find connection anomalies

    Under Article 12 of the French order of 21 July 2015, the owner of a collection system carries out a diagnosis at least every ten years. It must estimate the infiltration and inflow of clean water and identify the main sectors with connection anomalies. The order allows any appropriate means, including CCTV inspection. A lateral launch survey gives evidence connection by connection for that diagnosis.

  2. Permanent diagnosis for larger systems

    Systems receiving 120 kg/day of BOD5 or more must also run a permanent diagnosis. The order lists the knowledge, control and monitoring of domestic and non-domestic connections among its contents. A lateral inspection programme can feed that monitoring year after year. Check the load class of your system and the compliance deadline that applied to it with the State water police service.

  3. Who owns which part of the lateral

    The French Public Health Code splits the connection. Works that bring wastewater to the public part of the connection are paid by the owner, and the commune checks the quality of their execution (Article L1331-4). The part under the public road, up to the inspection chamber, can be built by the commune and then joins the public network (Article L1331-2). Record on each report where a defect sits relative to that boundary.

  4. New laterals are part of acceptance tests

    For new works, water agency guidance on acceptance control states that the visual or CCTV inspection covers the whole length laid, including connections, not only the main. Observations are coded to NF EN 13508-2. Tests are run by an accredited operator independent of the works contractor, so a contractor's own lateral survey does not replace them.

FAQ

Sewer operators' questions about lateral inspection.

How far does the satellite camera go into the lateral?

Up to 45 m for both the iPEK ROVION SAT II and the Envirosight ROVVER X SAT II, according to their manufacturers. The real distance depends on bends, deposits and lateral diameter.

Do we need to enter properties?

No: the system works from the public main. Access from the property side is only useful when the lateral is too long or blocked for the satellite camera.

What image quality can we expect?

The Envirosight ROVVER X SAT II carries a 5 MP pan-tilt targeting camera with a 130° field of view, according to its manufacturer. In the main, the Easy-Sight X5-HT films in 1080p with 10x optical zoom and measures cracks by laser, according to its manufacturer.

Is a standard mainline crawler enough?

To see a junction opening and spot an intruding connection, a crawler with a pan-tilt camera is enough. To inspect the lateral along its length, you need a lateral launch system or a push camera from the inspection chamber.
