Case Study: Restoring a Damaged Piezometer
Case Study: Restoration of a damaged piezometer without re-drilling
In groundwater monitoring and piezometer management, unexpected situations can compromise instrument functionality and data continuity. In this case study, Tecnopenta Srl successfully resolved a two-inch piezometer issue caused by a landslide, restoring full operability without requiring a new borehole.
Situation Analysis
The client contacted Tecnopenta Srl after a piezometer malfunction in a geologically unstable area. The landslide had deformed the piezometer tube and blocked the water level sensor, making it inoperable.
The main challenge was accessing the blocked sensor and continuing measurements without major disruption. Drilling a new borehole would have been costly and caused the loss of historical data.
The Solution by Tecnopenta Srl
Following an on-site technical assessment, our specialists removed the blocked sensor despite difficult access conditions. The operation was successful, avoiding further damage to the piezometer.
A miniaturized level sensor was installed, chosen for its compact size and ability to provide reliable measurements in challenging environments. The client resumed monitoring activities immediately without the need for a new borehole.
Results
- Full restoration of existing piezometer functionality
- Uninterrupted data collection and preserved historical series
- Significant cost savings from avoiding new drilling
- Rapid resumption of environmental monitoring
This case highlights the importance of a competent, flexible technical approach in environmental monitoring. Innovative and targeted interventions can solve complex situations and deliver cost-effective results.
