INTEGRATION OF IOT BASED SYSTEM FOR MONITORING HYDROGEOLOGICAL SYSTEMS TO ACHIEVE GROUNDWATER SUSTAINABILITY

Piezometer nests are used globally for characterising and monitoring various aquifers systems in various areas of groundwater based water supply systems. ASMITAS has been used to increase groundwater safety and hence a better decision making during the new tube well installation in Bangladesh. Integration of IOT based hydrogeological system with ASMITAS platform can be proved vital for monitoring contaminant profile as well as groundwater level. A very high precision water level sensors with auto loggers in 3 intervention areas in Bangladesh, were installed to monitor groundwater level in different aquifer systems. Data were collected in both wet season and dry season for characterising aquifer behaviour. The integrated digital platform is capable of capturing geological and hydrogeological data, which is further integrated with other commercial tool like POWER BI, GeoGIS for improved groundwater sustainability. A holistic source characterisation and long-term monitoring of aquifer system can be helpful in explaining undefined characteristic of aquifers and quite helpful in designing resilient groundwater management. Harnessing the local geological and hydrogeological know-how in digital way is a way forward for accelerating SDG 6.0 for providing safe drinking water as per WHO recommendation. The power of digitalisation can be vital in increasing the ROI and reaching the SDG goals faster. Data driven intelligence from sub surface characterisation and groundwater monitoring is necessary for long term sustainability perspective. The integration and ascending use of digital platform for data collection, and its management may significantly enhance the decision-making capabilities for arsenic mitigation at national and local level as well as for producing sustainable groundwater management strategies. A transparent decision tools may be necessary to capacitize the local technocrat to make rational decision and can help private sector to improve their productivity and income.
