Sewer & Infrastructure

Infrastructure robots go where people shouldn't: inside sewers, pipes, tanks and boilers. Camera crawlers and climbing robots record the condition of each asset, so repairs can be planned rather than rushed after a failure.

Buying advice

A crawler does not end confined-space planning

Under OSHA's 29 CFR 1910.146, entry into a permit-required confined space brings atmospheric testing, permits, training and rescue arrangements. A crawler cuts how often people go below ground, yet launching it, clearing a blockage or recovering a trapped unit can still draw someone towards an entry. Plan those cases before you buy. Ask each maker how its crawler is retrieved if it becomes stuck, what winch or cable recovery is offered, and how often recovery has needed a person in the pipe. If you use a climbing robot such as the Gecko Robotics Toka inside a tank or boiler, placing it there may itself count as a permit entry, so check with your safety lead.

Plan data for the asset owner's long view

Inspection footage is only valuable if it can be compared with the next survey of the same pipe. Directive (EU) 2024/3019, the recast urban wastewater treatment directive, sets duties for how EU operators collect and treat urban wastewater, and network condition data feeds the planning behind them. Agree with the asset owner how runs are referenced to manholes, how footage and condition scores are stored and for how long, and who owns them when a contract ends. Ask the makers of the Envirosight ROVVER X, RedZone Solo and Sewer Robotics LISY to show a repeat survey of the same line, so you can judge how consistent their results are over time.

Budget for wear, cleaning and processing

By October 2026, the SuperDroid Pipe Robot opened the price range at around $25,000 and the Gecko Robotics Toka closed it at around $200,000, and not one was quote-only. Running costs follow the hours spent underground: camera heads and lights get damaged, cables wear and pipes often need jetting before a useful survey is possible. Add software seats, data storage and the staff time needed to review footage and write condition reports. Ask whether repairs are carried out in your country and how long a unit is away, and consider a spare camera head so that one breakdown does not stand a crew down.

Common questions

Why use robots for sewer inspection?

Crawlers record pipe condition without anyone entering the network, which keeps crews out of confined spaces and creates a consistent record for planning repairs.

What data do inspection robots provide?

Typically video and condition data that can be coded against your inspection standard and used to prioritise repairs. Formats vary by maker, so confirm compatibility with your asset software.
