Use Case #4: River Water and Groundwater Monitoring System
- The ground water quality data is collected manually, for a few parameters such as temperature, level and TDS. The ground water in Guwahati city is polluted by iron, Arsenic and fluoride content.
- Central Water Commission is monitoring water quality at 531 key locations covering all the major river basins of India. At present the water quality network covers 67 main rivers, 138 tributaries and 64 sub-tributaries.
- CWC is maintaining a three tier laboratory system for analysis of the physic-chemical parameters of the water. The Level-I laboratories are located at 295 field water quality monitoring stations on major rivers of India where physical parameters such as temperature, colour, odour specific conductivity, total dissolved solids, pH and dissolved oxygen of river water are observed.
- There are 18 Level–II laboratories located at selected division offices throughout India to analyse 25 nos. of physico-chemical characteristics and bacteriological parameters of water.
- Level-III/II+ laboratories are functioning at Varanasi, Delhi, Hyderabad, Coimbatore and Guwahati where 41 parameters including heavy metals / toxic parameters and pesticides are analysed.
- Traditional water quality measuring of the Varanasi river involves the manual collection of water at various locations, which is inefficient.
Key aims for River Water and Groundwater Monitoring System:
- To assess the nature and extent of surface water pollution,
- The key objectives of this Use Case are to:
- Understand the environmental fate of different pollutants,
- Evaluate the effectiveness of pollution control measures in place,
- Evaluate the water quality trend,
- Asses the fitness of water for different uses,
- To understand the major factors controlling ground water chemical quality.
How LOTUS will improve River Water and Groundwater Monitoring System:
- For the Varanasi river water quality monitoring, the water quality parameters will be monitored using LOTUS sensor.
- Integrating the LOTUS IoT solution will provide real-time information of several water quality parameters of the Varanasi river which will then be sent automatically disseminated through website of CWC/India-WRIS for the public,
- For both cases, there will be the emplacement of LOTUS sensors; they will be integrated into a common probe with the wireless communication capability and IoT functionality.
Outcomes of Use Case 4:
- The quality of life will be improved because poor water quality will no longer spread diseases nor hamper socio-economic progress.
