*Including contract renewals

1. Support for Acoustic Leak Detection Surveys Based on Leak Risk Assessment

By utilizing satellite data for pipeline risk assessment at meter-level resolution, the solution enables high-resolution identification of current and near-future leak risks. It also supports mesh-level leak risk assessment depending on application needs. By narrowing down areas with high potential for leaks, it allows users to easily identify priority investigation zones, enabling efficient maintenance and management.

2. Support for Developing Water Pipe Replacement Plans Based on Regional Characteristics

By combining 'health condition' (leak risk assessment results) based on pipeline diagnostics with 'importance,' which comprehensively considers impacts on all facilities and daily life—from residential homes to critical water supply facilities such as hospitals, schools, and evacuation centers—multiple 'priority replacement scenarios' can be created. Through scenarios tailored to regional characteristics, the solution supports the rational and transparent determination of pipeline replacement priorities, facilitating highly effective planning.
