City: Bengaluru

“We had to take Cauvery connections as the common borewell tap went completely dry last summer. Even then, we cannot get a bucket of water without using motors,” said Hajira Bhanu, resident of Triveninagara slum in KR Pura. This slum — 'declared' or officially recognised by the Karnataka Slum Development Board (KSDB) — is comparatively developed. Yet the only water source for nearly 60 houses here is the Cauvery, which comes very faintly for less than three hours, twice a week. The residents have installed motors in their homes to draw water, which is considered illegal by the Bangalore Water…

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…

Urban Heat Islands (UHI) are areas within cities that experience significantly higher temperatures than their rural counterparts due to human activities, concretisation, and lack of vegetation. Bengaluru, the fifth most populous metropolis (Census of India, 2011) and one of the rapidly growing cities in India, is no exception. In the last two decades, the city has seen a rapid rise in built-up area from 37.4% to 93.3%. The pressure of urbanisation has not only affected the natural and ecological resources but is also impacting the city’s livability because of rising temperature levels. Unlike sudden disaster events like landslides or floods,…

Ambedkar Nagar, located in Kodathi panchayat, is a rapidly expanding neighbourhood in Bengaluru's outskirts. Young professionals socialising, walking to their workplace, waiting for their cabs—this area reflects Bengaluru's bustling IT ecosystem. Water tankers are a common sight, supplying water to local buildings. From small eateries to salons, the area has all the essential facilities for everyday life. The Wipro office premises are located on one side of Ambalipura-Sarjapura Road, while opposite its Kodathi gate, NPS School Road is lined with brightly painted, four-storey Paying Guest (PG) accommodations. But this growth has come at a steep cost, especially for the environment.…

The dependency on the Cauvery River for water and the depleting groundwater levels, keep Bengaluru on the edge of a crisis every summer. As the city expands rapidly, it faces a significant challenge – how to manage groundwater sustainably, while meeting the growing demand. Borewells are a common solution for water needs, but strict regulations govern their digging and usage. Bengaluru is classified as a 'notified area', due to overextraction in many places, so borewell digging and extraction are strictly regulated.  However, poor implementation of rules by civic utility bodies undermines their effectiveness. So, how can a Bengalurean dig a…

Every summer, Bengaluru grapples with its recurring water crisis, despite increased allocation of Cauvery water by the Supreme Court. The city currently has access to 24 thousand million cubic feet (TMC) of Cauvery water, but even with this supply, the Chief Minister admitted last summer that Bengaluru still faces a shortage of 500 million litres per day (MLD).   So, will Bengaluru reach water sufficiency this year? Or will the struggles of 2024 — when some areas of the city faced acute water shortage — be repeated? Speaking to Citizen Matters, Ram Prasath Manohar, Chairman, Bengaluru Water Supply and Sewerage…

In a quiet corner of Buragunte village, a transformation has been taking shape — one that turns kitchen waste into nourishment for the land and, in turn, provides food for the families of the women who made it happen. What started as a simple conversation has now evolved into a collective effort, spearheaded by one determined woman, Lalitha Akka.  Residents of Buragunte village under Anekal Taluk in Sarjapura, had long followed the waste disposal practice most commonly observed in our cities and towns — they would simply hand over their mixed waste to the collection vehicle from Billapura Gram Panchayat,…

Bengaluru gets its water from a reservoir 90 kilometres away and 350 metres below the city's elevation. The Bangalore Water Supply and Sewerage Board (BWSSB) has to spend approximately  ₹3 crore daily on electricity charges to pump this water to meet only half the city's needs. This is for the four stages of Cauvery water supply, which provide 1,460 Million Litres a Day (MLD). With Cauvery Stage 5 delivering an additional 750 MLD, the costs are expected to rise significantly. On the other hand, the BWSSB, based on the findings of a study conducted by the Indian Institute of Science…

Solid waste management is perhaps among the most overwhelming problems that Indian cities are grappling with today. But while the complexities around waste management in big cities are discussed widely, the challenges faced by smaller Indian cities and towns are even more complex due to limited scale, inadequate funding and institutional capacity constraints. Tier-1 and some Tier-2 cities have set up infrastructure and allocated resources for waste processing, but in general, small cities struggle to do so. As a result, waste processing in these cities is almost negligible, with only a few exceptions.   Chikkaballapura is a Tier-2 city located about…

As summer starts kicking in, the strong likelihood of a critical water shortage in Bengaluru is again making headlines. A recent report by BWSSB and Indian Institute of Sciences (IISc) reported 80 wards that will face severe water crisis and scarcity this summer and recommended switching to Cauvery connections, as groundwater is depleting at a faster rate.  With back-to-back government orders on groundwater extraction and restrictions on water usage, the administration is scrambling to manage the crisis. Citizens, too, are acutely aware of the looming scarcity — many have already begun cutting down usage, and seeking alternative sources to brace…
