Bengaluru, Karnataka: A recent study by the Indian Institute of Science (IISc) has highlighted growing groundwater stress across several parts of Bengaluru, prompting the Bangalore Water Supply and Sewerage Board (BWSSB) to roll out a ₹10 crore emergency action plan aimed at mitigating potential water shortages during the upcoming summer months.
According to findings from the IISc-led analysis, groundwater levels in around 65 wards across Bengaluru have shown significant depletion trends. The research used advanced Artificial Intelligence (AI) and Internet of Things (IoT)-based monitoring systems to analyze borewell data, recharge patterns, and water extraction levels across the city.
AI-Based Study Identifies High-Risk Areas
The study identified multiple localities across northern, western, and eastern Bengaluru where groundwater levels are declining rapidly. These include several residential and apartment-dominated areas that rely heavily on borewells for daily water supply.
Researchers analyzed seasonal variations and groundwater recharge patterns to forecast possible stress during peak summer months when water demand typically increases. The report indicates that urban expansion, increased groundwater extraction, and lower recharge levels have contributed to declining water tables in certain areas of the city.
BWSSB Launches Emergency Measures
In response to the findings, BWSSB has introduced a ₹10 crore preparedness plan to ensure stable water supply across affected zones. The action plan includes monitoring borewells, repairing pipeline leakages, and improving operational efficiency of water treatment and reverse-osmosis (RO) plants.
Authorities also plan to deploy water tankers and temporary storage tanks in high-risk localities, particularly in densely populated neighbourhoods and apartment clusters. Construction projects will be required to use treated water instead of potable water, while strict penalties may be imposed for non-essential uses such as vehicle washing or gardening with drinking water.
Implications for Bengaluru’s Urban Growth and Real Estate
Water availability remains a critical factor influencing urban planning and real estate development in Bengaluru. Rapid residential expansion and increased commercial activity have placed pressure on groundwater resources in several parts of the city.
Developers and housing communities are increasingly adopting rainwater harvesting, wastewater recycling, and sustainable water management systems to reduce dependence on borewells.
Urban planners note that strengthening water infrastructure and improving groundwater recharge mechanisms will be essential to support Bengaluru’s long-term growth as a technology and commercial hub.
