Vishal Borewell Drilling piezometer Digital water Level Recorder (DWLR)
Understanding Piezometers for Effective Groundwater Monitoring
A piezometer measures groundwater pressure, or piezometric head, at a specific location. It helps identify seepage patterns, potential piping zones, and the effectiveness of seepage control methods. Piezometers in sturdy casings can be buried or driven into the ground to measure groundwater pressure at the installation site. Pressure gauges, also known as transducers, convert this pressure into an electrical signal using vibrating-wire, pneumatic, or strain-gauge functions. These piezometers connect to the surface, where data loggers or portable readout units provide quick and frequent readings.
What is the purpose of a Piezometer DWLR Digital Water Level Recorder?
A piezometer serves several key purposes:
It investigates how water in soil or rock pores affects load-bearing capacity. As pore water pressure increases, the soil’s load-bearing ability may eventually fail.
Piezometers monitor groundwater levels and flow patterns.
They determine water flow patterns in earth/rock fill, concrete dams, and their foundations.
Piezometers help draw the phreatic line.
They ensure compliance with Central Ground Water Board (CGWB) NOC requirements.
Piezometers evaluate rainwater collection methods.
They aid in crop planning and agricultural drought forecasts.
Piezometer Telemetry and Non-telemetry for groundwater monitoring
In the realm of groundwater monitoring, piezometers emerge as invaluable assets, providing a window into the hidden world beneath our feet.
Understanding the Functionality of Piezometers in Groundwater Monitoring
Groundwater is vital for drinking water, agriculture, and industry. To manage and monitor it, tools like the borewell drilling piezometer digital water level recorder have been developed. This device provides real-time data on groundwater levels.
Piezometers measure groundwater pressure. They include a casing, filter, and water level sensor. The casing, often made of PVC or stainless steel, is installed vertically. The filter keeps soil out, ensuring accurate readings. The water level sensor converts groundwater pressure into an electrical signal.
The digital recorder automates data collection, reducing human error and saving time. It connects to a data logger, storing and processing data at set intervals. This continuous record can be easily analyzed with specialized software.
Real-time data from the recorder allows for timely decision-making. For instance, a significant drop in groundwater levels can prompt conservation efforts. Additionally, the recorder can integrate with other systems, providing a comprehensive understanding of groundwater dynamics.
Beyond monitoring levels, the device measures temperature and conductivity, offering insights into groundwater quality. High conductivity levels, for example, may indicate contamination, helping assess water suitability for various uses.

Instructions for Piezometer Installation and Monitoring
A piezometer is a bore well or tube well used to measure water levels with a tape, sounder, or automatic device. It also collects water samples to assess quality. For CGWA NOC compliance, the installation standards for piezometers are as follows:
First, position the piezometer at least 50 meters from the pumping well. Ensure the diameter is between 4 and 6 inches. The depth should match that of the pumping well. If more than one piezometer is installed, one should monitor the shallow groundwater regime. This makes it easier to monitor both shallow and deep aquifers.
Next, measure the water level once a month with a precision of up to one centimeter. Use a meter unit with two decimal places. For accurate measurements, use a sounder or Automated Water Level Recorder (AWLR) with a telemetry system. Measure the water level only after stopping the pumping for four to six hours.
Additionally, provide all information about the piezometer, including coordinates, reduced level, depth, zone tapped, and assembly lowered. Share these details with the State Groundwater Monitoring System and the National Hydrograph Monitoring System of the Central Ground Water Board.
Twice a year, check the groundwater quality before and after the monsoon (May/June and October/November). Conduct quality tests at GWD Analytical Labs or NABL-approved laboratories. Send a one-liter groundwater sample collected during the pre-monsoon for chemical examination to the relevant Regional Labs.
Finally, build a permanent display board at the piezometer site to provide the location, piezometer/tube well number, depth, and zone tapped. Address any site-specific requirements for measurement access and safety as needed.
