Bengaluru’s Thirsty Future: A Wake-Up Call for Urban India

Bengaluru, the Silicon Valley of India’s IT capital, is facing several water crises that threaten its growth and could be a precursor to similar challenges in other Indian cities. Bengaluru’s population has exploded from 5.1 million in 2001 to nearly 13 million today. This rapid urbanization, accompanied by unchecked industrial growth and sprawling residential complexes, has placed an immense strain on the city’s natural resources, especially its water supply.
Traditionally reliant on the Cauvery River for much of its drinking water, the city now finds this source stretched to its limits. The river, approximately 100 kilometres away, cannot sustainably meet the escalating demand. Compounding the issue, the city’s infrastructure, plagued by poor management and inadequate investment, struggles with over 40% of unaccounted water loss due to leaks and theft.
The city requires a total of 2,600 million litres per day (MLD) for drinking and industrial purposes, but the current supply falls significantly short. “Bengaluru is facing a shortage of 500 MLD,” Karnataka Chief Minister Siddaramaiah disclosed after a critical meeting on the city’s water supply on Monday. According to the Chief Minister, 1,450 MLD is currently being pumped from the Cauvery River, and about 650 MLD is sourced from borewells, highlighting a significant deficit.
Urban development has not only strained the existing water infrastructure, which suffers from significant losses due to leaks and theft, but has also led to a dramatic depletion of groundwater levels. Experts estimate that groundwater has decreased by over 100 feet in several areas over the past few decades, pushing the city closer to a potential ‘day-zero’ scenario where taps could completely dry up.
The environmental impact is visible in the city’s deteriorating lake systems, which are polluted and encroached upon. The environmental impact can be seen in the city’s deteriorating, polluted, and attacked reservoir system. The infamous Belandur Lake often makes headlines for bubble bursts and fires, highlighting serious pollution issues. This water scarcity also exacerbated social inequality. Wealthy residents often rely on expensive private water mains and deep wells, leading to water shortages, while poor communities face daily problems, and access to water is severely restricted.
In response to the crisis, the local government has promoted initiatives such as mandatory rainwater harvesting for new buildings and the rejuvenation of local lakes. However, these efforts face challenges in terms of enforcement and effectiveness. Technological interventions, including water recycling and advanced irrigation systems, are being adopted but need more widespread implementation to make a significant impact.
Bengaluru’s situation serves as a warning to other rapidly growing Indian cities. Urban centres like Chennai, which recently faced acute water shortages, and Delhi, known for its plummeting groundwater levels, are recognising the urgent need for sustainable water management practices.
Experts argue that a multi-faceted approach is necessary to address the crisis. This includes overhauling ageing water infrastructure, enforcing stricter pollution and land use regulations, investing in modern water conservation technologies, and fostering community engagement in sustainable practices. As Bengaluru grapples with these challenges, the city’s struggle is a wake-up call for urban India, highlighting the critical need to balance development with sustainable resource management to secure a viable future for all residents.
