Bengaluru's Water Woes: A Call to Action on World Water Day

Introduction

Bengaluru, often hailed as India's Silicon Valley, is facing a severe water scarcity. The recent depletion of groundwater sources has pushed the city to rely heavily on external sources, with the iconic Cauvery River unable to meet Bengaluru's escalating water demands. What occurred earlier this month serves as a stark warning – unless proactive measures are taken, the city's water woes will only exacerbate.

The Current State of Affairs

To understand the gravity of the situation, consider this: Bengaluru's daily water requirement stands at a staggering 2,600 million liters, out of which only 1,450 million liters are supplied from the Cauvery river. The rest is sourced from borewells, which contribute 650 million liters. Despite these efforts, there remains a significant shortfall of 500 million liters per day, leading to the drying up of 6,900 borewells across the city.

Consumption Patterns

The way Bengaluru consumes water reflects a pressing need for sustainable solutions. A staggering 1,940 MLD of wastewater is produced daily, with only 1,239 MLD being treated. With 72% of water allocated for domestic use, and 24% for commercial and industrial purposes, it's evident that a comprehensive strategy is urgently needed to address consumption patterns.

A Call for Sustainable Solutions

The water crisis in Bengaluru is not an isolated incident. Many cities across India are on the brink of a summer water crisis as reservoir levels plummet to five-year lows. However, amidst these challenges, there lies an opportunity for businesses to collaborate with the government in implementing innovative solutions such as rainwater harvesting technologies and adopting nearby lakes for conservation efforts.

Investing in Water Infrastructure

One of the key factors exacerbating the crisis is the lack of investment in water infrastructure. A staggering 39% of the water supply is lost before it reaches homes due to leaks, highlighting the urgent need for improvements. Urban utilities must invest in piped water supply systems, smart meters, and efficient distribution to curb these losses and ensure a reliable water supply for all.

Embracing Sustainable Growth

Bengaluru's population has surged from 4.1 million in 2001 to 14.4 million in 2020, leading to a depletion of groundwater and the drying up of borewells. While policies around rainwater harvesting exist, there is a need for a concerted effort to go beyond tokenism and focus on outcomes and impact. It is imperative to lay the groundwork for sustainable growth that does not come at the cost of our precious water resources.

Restoring Water Bodies

The city of Bengaluru, once known for its beautiful lakes, has seen many of these water bodies encroached upon or misused. Restoring and rejuvenating these lakes is crucial for replenishing groundwater and ensuring a sustainable water supply. Activists and NGOs in Bengaluru have been working tirelessly to restore the city's lakes, and policymakers must join forces with them to amplify their efforts.

Harnessing Data and Technology

In the digital era, data and technology can play a pivotal role in water conservation efforts. Techniques like calibrated pressure management in water pipes can significantly reduce demand. Real-time data on water consumption and reserves are essential for efficient management and governance of water resources.

The Role of Businesses in Water Conservation

Bengaluru is home to companies with some of the highest valuations and revenues in the country, many of which have taken proactive measures to conserve water. Infosys, Brookfield Properties, Walmart Global, SAPS LABS India, and WIPRO are among those leading the way with initiatives such as low-flow fixtures, sewage treatment plants, rainwater harvesting, and water recycling. These efforts not only help in conserving water but also set an example for others to follow.

Conclusion

On this World Water Day, let us pledge to make a difference. Whether through small changes in our daily lives or large-scale initiatives in our communities and businesses, each of us has a role to play in ensuring a water-secure future for all. Let us come together to embrace sustainable water management practices and protect this most precious resource for generations to come.
