Hubei Fly-Ash Landfill Long-Term Leak Monitoring
Background
A 57,154 m² flexible fly-ash containment cell with double-HDPE liner — SENEVEN deployed its long-term online leak-monitoring system to deliver real-time integrity surveillance during operation.
Challenge
Harsh fly-ash operating conditions demand long-term reliability and pinpoint accuracy from the monitoring grid, and a robust algorithmic distinction between genuine leaks and environmental noise.
Solution
1,565 sensing electrodes on a 6 × 6 m grid with 52 powering electrodes above and 52 below the liner, paired with cloud data processing and automatic-alert algorithms — delivering 24/7 real-time monitoring and coordinate-level leak localization.
Results
Verification by deliberate puncture: system raised an accurate alert and pinpointed the defect
Closed-loop validation from data acquisition through localization to in-situ excavation
Confirmed long-term effectiveness and sub-metre localization accuracy
Provides reliable assurance for cell operations and groundwater protection
