In general, the water reclamation work refers to a work that directs the flowing sewage to bypass a buried pipeline, and prioritizes various undigging works or works such as non-excavation work or CCTV photography to repair a pipeline buried underground. It is almost done.

Recently, instead of the excavation work to excavate earth and sand using heavy equipment to repair the pipeline, to determine the abnormality of non-excavation work and pipelines that can repair the pipeline without excavating the earth and sand and to determine the exact location requiring repair. CCTV (Closed-Circuit Television) shooting is being actively performed.

The above-mentioned non-excavation work and CCTV photographing are likely to damage road communication, underground communication cable, power cable and city gas pipe while the excavation work uses heavy equipment such as an excavator, and long-term traffic flow obstacle. Compared to many risks and risks, most of the problems caused by the excavation work have been solved.

Accordingly, as the above-mentioned non-excavation work and CCTV photographing work rapidly increase in the construction site, the water turning work that follows this is also more urgent than ever before.
