According to water supply statistics, the percentage of water pipes that have exceeded their statutory useful life was 6.3% in fiscal year 2007, and it has increased to 16.3% in fiscal year 2017, with further increases expected in the future. On the other hand, the renewal rate decreased from 0.94% in fiscal year 2007 to an annual rate of 0.70% in fiscal year 2017, indicating that the budget for renewals is not keeping pace with the increasing demand for updates. As a result, the importance of asset management for the stable continuation of water supply operations in the future has been pointed out. To achieve this, it is essential to maintain pipeline data and assess the condition of pipelines through daily maintenance, as well as to carry out planned renewals based on this information.

As the aging of pipelines buried during the period of rapid economic growth progresses, it is necessary to implement preventive maintenance management by utilizing pipeline data and inspections to sustainably maintain water pipes in a sound condition. To examine the condition inside the pipes through diagnostics, verification of cleaning effects, prioritization of pipeline renewals, and investigation of valve failure causes, it is desirable to conduct internal inspections economically and effectively in a short time without interrupting water supply. This is made possible by using internal camera inspections of water pipes. By observing the interior of the pipes without interrupting the water supply and recording it as image data, it is possible to provide fair and accurate decision-making materials in real-time. The image data can reveal the living conditions inside the pipes and the causes of troubles that were previously unknown, allowing for persuasive communication and explanations to the council and residents. As a new economical and reliable tool for the water supply industry, various applications and developments are expected in the future. *For more details, please refer to the PDF document or feel free to contact us. *This PDF document is a digest version.

Today, as most of the population has access to tap water, the concerns of consumers have shifted towards the quality of the supplied tap water, specifically whether it is safe and pleasant to drink, and whether it can be used confidently for daily life and business. To achieve a sustainable water supply in the future, it is essential to adequately meet the needs regarding tap water quality and to further enhance consumer satisfaction. However, there are instances where it is difficult to say that the high-quality water produced at water treatment plants is delivered to consumers while maintaining its quality. This is partly due to issues in water storage tanks, as well as the deterioration of water quality in the distribution pipelines, which has been increasingly pointed out. We have introduced some of the research cases and insights that our association has accumulated regarding these causative phenomena in the "Water Pipe Camera Survey Handbook." *For more details, please refer to the PDF document or feel free to contact us. *This PDF document is a digest version.
