SomeQ Technology Co., Ltd. (Headquarters: Goka-machi, Ibaraki Prefecture; Representative Director: Sadao Hishiki) participated in the Nikkei Regional Revitalization Forum, 'Regeneration of Water and Sewage Systems and Infrastructure Management,' held in Saitama Prefecture on May 21, 2026. Representative Director Sadao Hishiki delivered a presentation on solutions for aging sewer pipe infrastructure.

In his corporate lecture titled 'Aging Sewer Pipes: How to Solve this Difficult Problem,' Hishiki explained the company's proprietary 'Toughness Construction Method' as a solution to the critical social issue of aging sewer pipes nationwide. He began by outlining the major challenges facing infrastructure: 'Maintaining and managing social infrastructure, including bridges, tunnels, and sewer pipes, is extremely difficult. Most infrastructure is built with iron and concrete because they are strong, cheap, and easy to use, but iron rusts quickly and concrete deteriorates rapidly.'

Regarding the theme of aging sewer pipes, Hishiki cited data from the Ministry of Land, Infrastructure, Transport and Tourism's nationwide survey, noting a serious situation: 201 kilometers of sewer pipes are classified as 'Urgency Level I' requiring action within one year, and 547 kilometers are classified as 'Urgency Level II' requiring action within five years.

To address this challenge, he emphasized, 'Everything depends on whether we can toughen everything. We want to realize the long-term life extension of existing social infrastructure, so that once repaired, it can be maintained for 50, 60 years, and beyond.' He elaborated on the 'Toughness Construction Method,' which enables the regeneration, life extension, and reinforcement of social infrastructure. As a case study, he referenced the use of the technology on the Naha Ohashi Bridge in Okinawa, noting its strength: 'We can coat bridge columns even in wet conditions using our uniquely developed new material.' He concluded by stating, 'We will continue to conduct further research to deliver technology that gains the trust and peace of mind of the public.'

He also participated in a panel discussion with industry, academic, and government experts, including Saitama Governor Motohiro Ono and Chika Abe, Senior Researcher at the Public Works Research Institute, to discuss water infrastructure as a cornerstone of future living.

In sewer pipe renovation, it is possible to drastically reduce renovation costs, shorten construction times, and minimize impact on the surrounding environment by repairing and reinforcing existing pipes using our proprietary new material without the need for conventional road excavation.

FAQ

染めQテクノロジィが提案する下水配管老朽化への解決策とは?

同社が開発した【強靭化工法】を活用します。道路を掘削せずに、独自開発の新素材を下水道内部にコーティングすることで、管の補修・強靭化を行い、改修費用の削減や工期の短縮を可能にします。

なぜ下水配管の老朽化が深刻な社会課題となっているのか?

高度経済成長期から整備された下水道管路の多くが、耐用年数(標準50年)を超え、道路陥没のリスクなどが顕在化しているためです。全面更新には莫大な費用と時間がかかる一方、点検から補修までの一貫した管理体制の構築が自治体にとって容易ではないことも背景にあります。

強靭化工法の主なメリットは何ですか?

道路掘削が不要であるため、周辺環境への影響を最小限に抑えられます。また、今ある管を交換せず補修することで、改修費用の大幅な削減と工期の短縮を実現し、長寿命化を可能にします。

沖縄県の那覇大橋での活用事例とはどのようなものですか?

橋の柱部分のようにウェットな(湿潤な)状態であっても、独自開発の新素材でコーティングすることが可能な技術であることを示す実証事例です。

今回登壇したフォーラムの主催はどこですか?

日本経済新聞社が主催し、埼玉県で開催された日経地方創生フォーラム「上下水道の再生とインフラマネジメント」です。
