Ensuring CGWA Compliance: The Solution
The overexploitation of groundwater reserves poses significant concerns for future water needs, prompting the Central Ground Water Authority (CGWA) to introduce new guidelines for groundwater extraction. Compliance with these guidelines is essential to safeguard water resources effectively. To adhere to CGWA’s latest directives, the following instructions must be followed:
Technical Specifications for Tamper-Proof Electronic Flow Meter:
| Specification | First Name |
|---|---|
| NOC | NOC will be issued by CGWA/SGWA |
| Flowmeter | Battery operated Digital Ultrasonic and Electromagnetic flowmeter |
| IP Standard | Water Flowmeter as per 4064:2014 standards and have IP 68 ingress protection |
| Test Certificate | NPL and NABL authorized laboratory |
Instructions:
- Mandatory Flowmeter Installation: Ultrasonic and Electromagnetic flowmeters must be installed.
- Compliance with ISO Standards: Water meters should be manufactured in accordance with ISO 4064:2014 Standards and feature IP 68 ingress protection.
- Accuracy Standards: Flowmeters must meet accuracy class 2, T50, following ISO 4064:2014 standards.
- Certificate Submission: Manufacturers are required to submit the latest meter certificate from FCRI, the National Physical Laboratory (NPL), or any government NABL accredited laboratory for every meter.
- Battery Operation: Flowmeters must be battery-operated, with no reliance on external power supplies from mains or renewable sources.
Technical Specifications for Tamper-Proof Telemetry System:
| Specification | Classification |
|---|---|
| Telemetry | Battery operated as well as an external power supply operated |
| Data Transmission | LoRa WAN or cellular phone (GPRS/3G/4G) |
| Parameter | Total flow, flow rate, level, EC (saline zone) |
| Vendor Server | Miety registered a secure cloud server |
| CGWA Server | CGWA data management |
Instructions:
- Data Storage in Power Failure: The CGWA necessitates that telemetry system data must be stored in a meter, even during power failures.
- Power Sources: Telemetry systems can operate with either battery power or external power supply.
- Data Transmission: Data should be transmitted via LoRa WAN or cellular phone (GPRS/3G/4G).
- Cloud Server Registration: Telemetry data should be transmitted to CGWA through a secure cloud server registered with the Ministry of Electronics and Information Technology (MeitY).
- Monitored Parameters: The telemetry system should monitor parameters including time stamps, cumulative volume, cumulative operating hours of the pump, and, at a minimum, transmit this data twice a day.
- Installation Specifications: The meter should be installed at the bore-well pump discharge line before any branching, with no bypassing of the pipe at the flow meter.
The web-based Data Management Software must be compatible with a standard PC featuring, at minimum, a Pentium Processor. This cloud-based software should offer web portal access for users to view customer data through a browser.
Once the data management platform server is operational, untampered data will be sent from the secure cloud to CGWA in real-time with robust cybersecurity measures in place.
