Regular inspection of water supply and sanitation networks helps to reduce accidents that occur in engineering communications. To check the regulatory and technical documentation is recommended to use tele-inspection systems that allow you to get the most accurate information about the technical condition of pipelines in a short time. The article deals with the review and analysis of modern technical systems for tele-inspection and trenchless repair of pipelines. The article considers the requirements of regulatory and technical documentation for such systems. We consider the classification of tele-inspection systems for diagnostics and repair of pipelines by functional characteristics. A review of the current market of domestic and foreign-made technical equipment has shown that all devices for TV inspection of pipeline networks can be classified as follows: push-through TV inspection systems, robot-controlled TV inspection systems and TV inspection systems for trenchless repair. A review of the current market of domestic and foreign-made technical equipment has shown that all devices for tele-inspection of pipeline networks can be classified as follows: push-through tele-inspection systems, tele-inspection systems with remotely controlled robots, and tele-inspection systems for trenchless repair
