What This Patent Covers

The patent protects a method for evaluating permeability of underground dam cutoff walls by comparing groundwater ages. The claims were rigorously examined against five prior art documents and successfully defended, indicating a robust and difficult-to-invalidate intellectual property right.

Competitive White Space

This patent primarily covers groundwater age comparison for underground dam leak detection. White space exists in developing real-time, multi-sensor monitoring systems for broader infrastructure integrity, or applying similar age-based principles to non-water-related geological fluid flows.

Economic Impact
Up to ~$1.5M/year in maintenance cost reduction (AI est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming an average annual maintenance cost of ~$35K/dam (AI est.) for inspection, repair, and water resource loss across 500 major underground dams, totaling ~$16.5M annually (AI est.). This technology's early detection and efficiency could reduce overall costs by ~10%. Calculation: (~$16.5M total annual cost (AI est.)) × 10% = ~$1.5M/year (AI est.).

Speed to Market
5× faster than in-house development
This technology's fundamental research and technical validation have been advanced by a national research institute, and the groundwater age measurement algorithm is assumed to be established. Developing a similar technology from scratch would likely require approximately 4 years for basic research, field testing, and algorithm construction. However, by licensing this technology, system implementation and operational startup could be achieved in approximately 10 months, assuming integration with existing observation wells and geological data, significantly accelerating market entry.

Technical Feasibility
This technology is based on the principle of measuring and comparing groundwater ages. It can maximize the use of existing observation wells and groundwater survey equipment, making it highly likely to be introduced without significant new infrastructure investment. The patent claims indicate that comparing specific substance concentrations is key to leak detection. It is estimated that this can be easily integrated into existing measurement infrastructure by combining it with general water quality analysis or isotope analysis techniques. Therefore, the technical hurdles for adoption are considered relatively low.
Success Scenario
Upon adopting this technology, licensees could move beyond uncertain leak detection methods that are influenced by water level fluctuations. By continuously monitoring groundwater age data, subtle leak indicators could be identified early, enabling proactive maintenance before extensive repairs become necessary. This is estimated to reduce annual maintenance costs by an average of 15% and establish a more stable water resource supply system with extended underground dam lifespans.
