Tenchijin Publishes Vol. 3 of 'Tenchijin Magazine' for Municipalities, Featuring 'Evaluation of Damage Risks and Criticality in Sewer Pipelines'

Tenchijin Inc., a JAXA-certified space startup that provides 'Uchu Suidokyoku,' a water DX solution supporting sustainable water utility operations using satellite data, published the third issue of 'Tenchijin Magazine' in May 2026.

This issue focuses entirely on 'Uchu Suidokyoku,' featuring discussions on predictive maintenance strategies, municipal adoption records, and case studies, centered on 'damage risk' and 'criticality' in sewer pipelines.

Copies are being distributed to municipalities, and the magazine is also available in PDF format.

Special Feature: Evaluating 'Damage Risk' and 'Criticality' in Sewer Pipelines Japan's sewer pipelines span approximately 500,000 km in total length, most of which were constructed during the period of rapid economic growth. The number of pipelines exceeding the standard service life of 50 years is expected to increase rapidly, and road collapses caused by sewer pipes amount to approximately 2,600 cases annually. Given limited personnel and budgets, this issue organizes perspectives on damage risk and criticality to help municipalities determine where to prioritize inspections and surveys.
