Clean and safe drinking water is a fundamental need, and Drinking Water Quality Monitoring Systems play a vital role in ensuring that every drop meets national and international standards. At AAXIS NANO, we deliver real-time water quality monitoring solutions integrated with advanced sensors, analyzers, telemetry, and cloud-based dashboards for accurate, continuous assessment of drinking water parameters.
This comprehensive guide explains what drinking water quality monitoring is, its key parameters, international and Indian standards, monitoring frameworks, data protocols, and how AAXIS NANO’s automated systems help maintain compliance, transparency, and public safety.
What Is Drinking Water Quality Monitoring?
Drinking Water Quality Monitoring (DWQM) refers to the continuous or periodic measurement of physical, chemical, and biological parameters of drinking water to ensure that it meets safe consumption standards defined by agencies such as WHO, BIS (IS 10500:2012), and CPCB.
It ensures that water supplied through treatment plants, pipelines, and distribution networks remains free from contamination, pathogens, and hazardous substances.
AAXIS NANO’s smart monitoring systems enable real-time online analysis of water quality, alerting operators and authorities about any deviations from prescribed limits through IoT-based dashboards and cloud platforms.
Why Drinking Water Quality Monitoring Is Important
- Public Health Protection: Early detection of contamination prevents disease outbreaks (e.g., cholera, typhoid, E. coli contamination).
- Regulatory Compliance: Meets national standards (BIS 10500) and WHO guidelines.
- Transparency & Accountability: Enables public utilities and industries to share verified, traceable data with authorities and consumers.
- Operational Efficiency: Helps in preventive maintenance of treatment plants and pipelines.
- Smart City Integration: Forms a key component of smart water management frameworks.
Key Parameters in Drinking Water Quality Monitoring
1. Physical Parameters
- pH: 6.5–8.5 (ideal for potable water)
- Turbidity: <1 NTU preferred (max 5 NTU)
- Color: <5 Hazen units
- Temperature: 20–25°C typical
2. Chemical Parameters
- TDS (Total Dissolved Solids): ≤500 mg/L
- Hardness (as CaCO₃): ≤200 mg/L desirable, 600 mg/L permissible
- Chloride: ≤250 mg/L
- Nitrate: ≤45 mg/L
- Iron: ≤0.3 mg/L
- Fluoride: ≤1.0 mg/L
- Arsenic: ≤0.01 mg/L
3. Microbiological Parameters
- Total Coliforms: 0/100 mL
- E. coli: 0/100 mL
4. Other Parameters
- Residual Chlorine: ≥0.2 mg/L at consumer end
- Conductivity: ≤500 μS/cm
- Dissolved Oxygen (DO): ≥5 mg/L (indirect indicator of biological stability)
AAXIS NANO’s online analyzers continuously track these parameters using high-accuracy electrochemical, optical, and spectrophotometric sensors linked to data loggers and telemetry units.
Indian and International Drinking Water Standards
| Standard Body | Reference Code | Key Focus |
|---|---|---|
| BIS (India) | IS 10500:2012 (2nd Revision) | Specifies limits for physical, chemical & microbiological parameters |
| WHO (World Health Organization) | WHO Guidelines for Drinking-water Quality (4th Edition) | Global benchmark for safety & acceptability |
| USEPA (United States) | National Primary Drinking Water Regulations | Legal limits for contaminants in public water systems |
| EU Directive | EU Drinking Water Directive (2020/2184) | Quality standards & risk-based monitoring framework |
In India, IS 10500:2012 is the governing document for all Drinking Water Quality Monitoring programs under Jal Jeevan Mission, AMRUT 2.0, and Smart City Projects.
Framework for Drinking Water Quality Monitoring
1. Source Monitoring
Regular testing of raw water sources — rivers, reservoirs, or borewells — for seasonal variations, turbidity, and chemical contamination.
2. Treatment Plant Monitoring
Real-time monitoring of influent and effluent from WTPs (Water Treatment Plants) for process optimization and filter efficiency.
3. Distribution Network Monitoring
Online sensors installed at intermediate and consumer-end nodes track residual chlorine, turbidity, pH, and conductivity.
4. Consumer Point Monitoring
Smart kiosks or portable test units verify water quality at the final delivery point to ensure public safety and confidence.
AAXIS NANO systems integrate all four layers into a single IoT-based platform, enabling central and local authorities to monitor and manage multiple sites in real-time.
Online Drinking Water Quality Monitoring Systems (ODWQMS)
An Online Drinking Water Quality Monitoring System (ODWQMS) consists of:
- Multi-parameter water quality sensors for pH, TDS, turbidity, chlorine, and ORP.
- Data loggers and analyzers for signal conditioning and calibration.
- Telemetry unit (GPRS/4G/LoRa) for real-time data transmission.
- Cloud dashboard / SCADA integration for visualization, alerts, and reports.
- Power options: 230V AC, battery, or solar for remote sites.
AAXIS NANO’s systems are IP65/IP67-rated, rugged, and compliant with MoHUA & CPCB guidelines for online environmental monitoring.
Protocols & Data Transmission Framework
To ensure interoperability and secure data exchange, AAXIS NANO systems support:
- Communication Protocols: Modbus RTU/TCP, SDI-12, RS-485, MQTT, HTTP/FTP.
- Networking: 4G LTE, LoRaWAN, Ethernet, or private VPN.
- Data Standards: JSON/XML format for server upload.
- Integration: Compatible with CPCB, Jal Jeevan Mission, and Smart City dashboards.
These protocols align with the Central Pollution Control Board (CPCB) and Ministry of Jal Shakti (MoJS) requirements for Online Water Quality Monitoring frameworks.
Quality Assurance, Calibration & Maintenance
Monitoring accuracy depends on proper calibration and maintenance:
- Sensor calibration: Monthly for pH, chlorine, turbidity, and TDS.
- Automatic cleaning systems: Prevent fouling in long-term deployments.
- Verification: Cross-check with portable reference kits.
- Data validation: Outlier removal, QC flags, and timestamp verification.
AAXIS NANO offers AMC programs and calibration services to maintain accuracy and uptime of monitoring stations.
