Transforming Water Management with Satellite Technology

The Japanese Ministry of Land, Infrastructure, Transport and Tourism has recently revised its "Water Supply and Sewerage DX Technology Catalog," prominently featuring the "Space Water Bureau" by Tenshijin, a JAXA-recognized space venture based in Tokyo. This innovative solution aims to support sustainable water supply initiatives by leveraging satellite data, and it showcases practical applications designed to enhance maintenance efficiency in water infrastructure.

Overview of the Water Supply and Sewerage DX Technology Catalog

As Japan faces challenges such as aging water infrastructure and a decline in experienced maintenance personnel, the need for enhanced digital solutions in water management is paramount. To address these issues, the Ministry established the catalog in March 2025, outlining innovative technologies for the water supply sector. The revised edition released on March 27, 2026, expanded the number of listed technologies from 163 to 189, and introduced valuable resources, such as demonstration technologies and information on available subsidies.

The catalog now features added functionality, including a free-text search and the capability to create technology comparison tables. These updates are designed to help municipalities and service providers efficiently compare and evaluate technologies crucial for the sustainable management of water services.

Introducing the Space Water Bureau

The "Space Water Bureau" stands out as a pioneering Water DX solution that utilizes satellite data to elevate sustainable water management practices. Since its launch in April 2023, it has achieved over 50 municipal contracts, underscoring its growing acceptance and utility within local governments.

1. Leak Risk Assessment and Support for Sound Hearing Surveys

One of the most significant features of the Space Water Bureau is its ability to conduct risk assessments for pipeline leaks using satellite data. This technology enables a granular analysis of pipeline integrity at a few-meter resolution, providing municipalities with high-precision insights into current and future leak risks. The system can also accommodate assessments on a mesh basis, helping identify areas with high leak probabilities and thereby facilitating targeted maintenance efforts.

2. Tailored Pipeline Renewal Planning Based on Local Characteristics

In addition to leak diagnostics, the Space Water Bureau assists in developing pipeline renewal plans that evaluate both the integrity of existing pipelines and the importance of various facilities, ranging from residential homes to critical infrastructure like hospitals and schools. By combining leak risk assessments with an evaluation of societal impacts during both normal operations and emergencies, municipalities can create multiple renewal priority scenarios. This flexibility allows for tailored approaches that consider community-specific challenges and objectives, ensuring that the planning process is both rational and transparent.

This innovative blend of rich historical data from local governments and cutting-edge satellite technology embodies the core value of the Space Water Bureau. By offering a fresh perspective on leak risk information, it evolutionizes traditional maintenance and planning strategies, making them more effective and responsive.

As we continue to bridge the wisdom of the past with the technologies of the future, efforts like the Space Water Bureau stand to create a new paradigm in water management, maximizing the efficiency of limited resources and amplifying positive impact on communities.
