Bengaluru Needs Effective Groundwater Monitoring

Monitoring groundwater level is like keeping a tab on your income and expenses—if you are spending more, it is a warning sign. You can cut down spending or find ways to earn more. Similarly, a city must decide whether to reduce extraction in certain areas or improve recharge methods, such as rainwater harvesting, wastewater treatment, or preserving open spaces. So, does Bengaluru have enough groundwater monitoring systems?
While a WELL Labs report estimates the city’s groundwater consumption as 1,392 million litres a day (MLD), BWSSB’s groundwater outlook report states that the extraction is only 800 MLD. This suggests a significant discrepancy in estimates, mostly because of insufficient data and inadequate monitoring points, highlighting the urgent need for proper tracking of groundwater resources.
