‘You should also report on Hegondanahalli Kere. A lake has been killed in the name of rejuvenation' — a message that I received from Chetan Gopal, Bengaluru-based lake conservationist and a member of the group ‘Friends of Lakes’, after my earlier story on Mullur Lake, another panchayat lake, was published.  Chetan regularly visits around 14 lakes in Sarjapura Road, Varthur and nearby areas, mostly outside the Bruhat Bengaluru Mahanagara Palike (BBMP) limit, and his observations bear out what our article underscored — that lakes on the peripheries of the city face common challenges that have left them in worse condition…

When the residents of TZED Homes, a community in Whitefield, faced water shortages, they did not immediately resort to using tanker water. Instead, they opted for an unconventional solution — treating and reusing wastewater for potable purposes. It was a difficult decision, and even more challenging to convince all community members to accept. "Until four to five years ago, we could access water at a depth of just 80 feet. However, tankers extracting water from commercial borewells have significantly affected our aquifer," says Babu, a resident closely involved in water management in the community. But, their efforts have paid off…

This April 10th, the Bangalore Water Supply and Sewerage Board (BWSSB) announced a water tariff hike after a gap of 11 years. The Board also decided to increase the tariff by 3% on April 1st every year. For most households, the tariff hike would mean paying ₹20 to ₹30 more on their monthly water bills this year. While the middle class sees a slight increase, slum dwellers face exorbitant costs, highlighting a stark inequality in access to clean, affordable water across the city. Here is how the tariff hike will reflect in your water bill this May. For domestic users…

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…

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.…

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…

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…

In an earlier article, we highlighted how Bengaluru lags behind in utilisation of funds received under the National Clean Air Programme, and how that, coupled with the lack of an elected municipal body, threatens the prospect of climate action. In November 2023, BBMP launched the Bengaluru Climate Action and Resilience Plan (BCAP), with the objective of addressing climate issues in the city.  Following the launch of the BCAP, a climate action cell was established in February 2024 to coordinate the work of different departments towards climate action. Some of these plans are to be realised utilising NCAP funds, either exclusively…

Bengaluru’s air quality has been seriously worsening post COVID. The annual levels of PM10 saw a decline between 2018 and 2021, but has been slowly increasing since then. Government authorities say that the air quality in Bengaluru is better compared to other cities. But while the PM2.5 levels may conform to the national standards, according to a Greenpeace report it is still four to nine times higher than WHO standards. There is thus a huge need for improvement. The city, however, has used very little of the clean air funds received under the National Clean Air Programme (NCAP). Also non-utilisation…

Once known for its pleasant climate, Bengaluru now faces a climate crisis. Rapid urbanisation, vehicular emissions, and construction dust have led to hazardous air pollution, with PM2.5 and PM10 levels endangering health. Rising temperatures, water scarcity, vanishing green cover, and rampant concretisation have intensified the urban heat island (UHI) effect. Erratic rainfall and groundwater depletion further threaten a water emergency, affecting households across the city. The Bengaluru Climate Action and Resilience Plan (BCAP) was introduced in November 2023 to build adaptation and resilience against climate change, but implementation gaps persist. The absence of a dedicated climate budget, lack of transparency…
