Piezometric Well

Accurate Monitoring of Water Resources

A piezometer is a fundamental tool in hydrogeological and geotechnical investigations, allowing for the monitoring and assessment of groundwater levels.

This technical solution provides critical data on the pressure and dynamics of aquifers, contributing to sustainable water resource planning and management.

Objectives and Applications

The primary objective of a piezometer is Monitoring the Water Table Level, which allows:

• Identifying the water table depth, facilitating the analysis of the availability and temporal variations of water resources.
• Understanding soil stability conditions, essential for engineering project planning and construction safety.
• Supporting environmental management, helping detect changes resulting from extraction activities, irrigation, or urban interventions, contributing to responsible environmental management.

Methodology and Installation

The installation of a piezometer is a rigorous process involving several technical steps:

• Drilling and Preparation

  The well is drilled to the desired depth, ensuring safe and representative access to the aquifer.

• Installation of Measurement Equipment

  After drilling, a piezometric tube equipped with a sensor or gauge is inserted to capture water column pressure data.

• Sealing and Protection

  Proper sealing is applied at the transition zone between the soil and the tube to prevent external interference that could compromise measurement accuracy.

• Calibration and Testing

  Once installed, the equipment is calibrated and tested to ensure that the measurements accurately reflect subsurface conditions.

Benefits and Impacts

Using piezometric wells offers multiple advantages:

• Precise Monitoring

  Continuous and accurate measurement of water levels enables a detailed analysis of aquifer behavior, essential for sustainability and safety studies.

• Support in Decision-Making

  The data collected provides a solid scientific basis for water resource management, contributing to informed decisions in construction projects and environmental interventions.

• Risk Prevention

  Constant monitoring can early detect changes that may indicate issues such as over-extraction or saline intrusion, allowing timely corrective actions.
