[ MiratecDrone Corp. ]Commences Provision of Drone-based Water Pipe Bridge
Inspection ServiceResponding to an increase in leaks and damage due to aging of water facilities
MiratecDrone Corp. (head office: Shinagawa-ku, Tokyo; President: Yasuyuki Sasaki;“MiratecDrone”), which is a Group company of MIRAIT Holdings Corporation, will commence the“Drone-based Water Pipe Bridge Inspection Service” for inspecting aging water facilities thathave become a problem in recent years.
In Japan, water facilities that were built from the 1960s to the 1970s are aging, and in recent
years there have been over 20,000 incidents of leaks and damage per year. In particular, thepercentage of water pipes exceeding the statutory useful life is 17.6%, and this percentage will
inevitably increase. (Source: 2018 Waterworks Statistics) In addition, in response to part of awater pipe bridge being damaged and collapsing in Wakayama City on October 3, 2021,
MiratecDrone believes that there is an urgent need for the inspection of the large number ofsimilar water pipe bridges in Japan and decided to establish systems for providing service andcommence provision of the service.
MiratecDrone has conducted field trials of water pipe bridge inspections using drones with
the Sakai City Waterworks and Sewerage Bureau in February 2020 and the waterworks
bureaus of several other local governments in the past. Based on the results, it was proventhat fractures in pipe surfaces, peeling of paint, rust and cracks in concrete used in bridges
can be accurately determined, and work has been conducted to practically implement theservice. As a result, the inspections of water pipe bridges that have been conducted from theshore with the naked eye until now can be recorded in detail from close proximity using acamera on a drone.
In addition, the service utilizes the functions of “Hec-Eye” software developed by Realglobe,Inc. (head office: Chiyoda-ku, Tokyo; President: Takahiro Ohata; “Realglobe”) to enable
experts on diagnosis of the deterioration of water pipe bridges and bridges to perform diagnosis

of video delivered by drones in real time from remote locations such as an office. It is also
possible to take high-definition images of areas suspected of deterioration from a variety ofangles as needed, and record and view the locations on a map.
The service will be provided to waterworks bureaus and business operators managing water
pipe bridges throughout Japan by dispatching pilots from MiratecDrone and partner companies
nationwide.
