VISHAL BOREWELL DRILLING PIEZOMETER DIGITAL WATER LEVEL RECORDER (DWLR)
Understanding Piezometers for Effective Groundwater Monitoring
A piezometer is a device that measures the pressure (more accurately, the piezometric head) of groundwater at a certain spot. It also aids in determining the pattern of seepage, prospective piping zones, and the effectiveness of seepage control methods implemented. Piezometers in tough casings can be buried or driven into the ground to measure groundwater pressure at the installation site. Pressure gauges (transducers) convert pressure into an electrical signal and can be vibrating-wire, pneumatic, or strain-gauge in function. These piezometers are connected to the surface and read by data loggers or portable readout units, allowing for faster or more frequent reading.
What is the purpose of a Piezometer DWLR Digital Water Level Recorder?
A piezometer can be used for the following purposes:
To investigate the effect of water in the pores of soil or rock on load bearing capability. The effect is more pronounced with increasing pore water pressure, finally leading to total breakdown of the soil’s load bearing capacity in some circumstances.
Piezometers are widely used in groundwater monitoring to determine groundwater level and flow pattern.
Water flow patterns in earth/rock fill, concrete dams, and their foundations must be deterined.
To draw the phreatic line.
Compliances with Central Ground Water Board’s (CGWB) NOC.
Evaluating the effectiveness of methods for collecting rainwater.
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 a vital resource that plays a crucial role in sustaining life on Earth. It is essential for drinking water, agriculture, and industrial purposes. To effectively manage and monitor groundwater levels, various tools and techniques have been developed. One such tool is the borewell drilling piezometer digital water level recorder, which provides accurate and real-time data on groundwater levels.
Piezometers are devices used to measure the pressure of groundwater at a specific point in the ground. They consist of a casing, a filter, and a water level sensor. The casing is typically made of PVC or stainless steel and is installed vertically into the ground. The filter prevents soil particles from entering the casing, ensuring accurate measurements. The water level sensor, also known as a transducer, measures the pressure exerted by the groundwater and converts it into an electrical signal.
The borewell drilling piezometer digital water level recorder takes the functionality of traditional piezometers to the next level. It is equipped with advanced technology that allows for automated data collection and real-time monitoring. This digital recorder eliminates the need for manual measurements, reducing human error and saving time.
The digital water level recorder is connected to a data logger, which stores and processes the collected data. The data logger can be programmed to record measurements at regular intervals, such as every hour or every day. This ensures that a continuous and accurate record of groundwater levels is maintained. The recorded data can be easily accessed and analyzed using specialized software.
One of the key advantages of the borewell drilling piezometer digital water level recorder is its ability to provide real-time data. This means that groundwater levels can be monitored and analyzed instantly, allowing for timely decision-making. For example, if the recorded data shows a significant drop in groundwater levels, appropriate measures can be taken to conserve water resources or address any potential issues.
Furthermore, the digital water level recorder can be integrated with other monitoring systems, such as weather stations or flow meters. This allows for a comprehensive understanding of groundwater dynamics and helps in identifying the factors that influence groundwater levels. By combining data from multiple sources, a more accurate and holistic picture of groundwater resources can be obtained.
In addition to monitoring groundwater levels, the borewell drilling piezometer digital water level recorder can also measure other parameters, such as temperature and conductivity. This provides valuable insights into the quality of groundwater and helps in assessing its suitability for various purposes. For example, if the recorded data shows high levels of conductivity, it may indicate the presence of contaminants in the groundwater.
Instructions for Piezometer Installation and Monitoring
A piezometer is a bore well or tube well that is exclusively used to measure water level by lowering a tape, sounder, or other automatic water level measurement device. Whenever necessary, it is also utilized to collect water samples for assessing the quality of the water. For CGWA NOC compliance, the general installation standards for piezometers are as follows.
The piezometer must be built or positioned at least 50 meters away from the pumping well where groundwater is being pumped out. The piezometer should have a diameter between 4 and 6 inches.
The piezometer’s depth should match that of the pumping well from which groundwater is being drawn. The second piezometer should monitor the shallow groundwater regime if more than one piezometer is placed. It will make groundwater aquifer monitoring easier for both shallow and deeper aquifers.
The frequency of measurement should be once per month, and the precision should be up to one centimeter. The measurement should be provided with a meter unit and two decimal places.
For accurate water level measurements, a sounder or Automated Water Level Recorder (AWLR) with telemetry system should be utilized.
After the pumping from the nearby tube wells has been stopped for roughly four to six hours, the water level in the piezometer should only be measured.
For the purpose of validating the piezometer, all information pertaining to coordinates, reduced level (relative to mean level), depth, zone tapped, and assembly lowered must be provided. These details should also be provided for the State Groundwater Monitoring System and National Hydrograph Monitoring System of the Central Ground Water Board.
Two times a year, in the months leading up to and following the monsoon (May/June and October/November), the quality of the groundwater must be checked. Quality testing can be done at GWD Analytical Labs or NABL-approved laboratories. Also, one sample of ground water (1 lt capacity bottle) obtained during the pre-monsoon and properly packaged may be forwarded to the relevant Regional Labs for chemical examination.
In order to provide the location, piezometer/tube well number, depth, and zone tapped of piezometer/tube wells for standard referencing and identification, a permanent display board should be built at the piezometer/tube well site.
Any further site-specific requirements for measurement access and safety may be handled.
