Bengaluru's Water Woes: How Fixing Leaks Could Unlock a Staggering Rs 330 Crore Revenue Boost for BWSSB

Bengaluru, the Silicon Valley of India, is grappling with a silent drain on its resources: colossal water losses. A groundbreaking study has shed light on a startling truth – the Bengaluru Water Supply and Sewerage Board (BWSSB) could inject a staggering Rs 330 crore annually into its coffers by simply addressing the pervasive issue of water leaks and inefficient management.

The report, spearheaded by researchers from the Ashoka Trust for Research in Ecology and the Environment (ATREE) and global consultancy WSP, paints a stark picture of 'Non-Revenue Water' (NRW).

This isn't just about drips and trickles; it refers to the colossal volume of treated water that is produced but never reaches customers or is billed. In Bengaluru, an alarming 48% of the city’s treated water falls into this category, vanishing before it can be used or accounted for. This figure dwarfs national and international averages, with cities like Chennai boasting a mere 15% NRW and the global average hovering around 20%.

Imagine nearly half of your meticulously treated water simply disappearing! This significant loss is a multifaceted problem, stemming from a combination of physical leaks due to aging infrastructure and commercial losses, including water theft, unbilled connections, and inaccurate metering.

BWSSB’s extensive network, stretching over 12,000 km of pipelines, many of which are decades old, is a prime culprit. These pipes, often made of asbestos cement, are susceptible to frequent bursts and leakages, especially under varying pressure conditions.

The study doesn't just highlight the problem; it offers a clear roadmap to financial health and water security.

By implementing strategic interventions to halve the current NRW rate, BWSSB could unlock that significant revenue increase. These interventions include proactive leak detection technologies, sophisticated pressure management systems across the network, and the crucial replacement of decrepit pipelines.

Furthermore, improving customer relationship management, upgrading to smart meters, and enhancing billing and collection processes are vital steps to curb commercial losses.

The benefits extend far beyond just financial gains. Reducing NRW means more water available for the city’s burgeoning population without tapping into new, often distant, and environmentally costly sources.

It signifies a move towards greater water equity, ensuring that every drop is valued and distributed efficiently. Environmentally, fewer leaks mean less energy spent on pumping water that never reaches its destination and reduced stress on natural water bodies.

This isn't an overnight fix; it requires sustained investment, technological upgrades, and a concerted effort from all stakeholders.

However, the potential rewards – a more robust financial standing for BWSSB, enhanced water security for Bengaluru, and a commitment to sustainable urban development – make this not just an option, but an imperative. The future of Bengaluru's water supply hinges on turning these losses into gains, making every drop count.
