Pollution

On the evening on May 12th, raw sewage gushed in from the eastern inlet for nearly 3 hours into Kaikondrahalli lake. With help from BBMP labourers provided by BBMP lakes Engineer Shilpa, and with many of the lake visitors and volunteers staying back at night to oversee the work, we could partially block the inlet. The blocking at the inlet was reinforced in the morning, but sewage continues to trickle in. With a JCB borrowed from Bren Construction, we tried to block the main source of the sewage inflow, but had to re-open it soon as the land owner and…

The Karnataka State Pollution Control Board (KSPCB) has introduced new norms for nitrogen level in the treated water that comes out from a sewage treatment plant. The step is meant to control nitrogen levels in the drinking water bodies. The new standards are made applicable to all STPs including those in Residential Apartment Complexes, Commercial Complexes and the large STPs of Urban Local Bodies ( ULB) such as City Municipal Corporation, Town Municipal Corporation etc. in Karnataka. The new notification limits Ammonia Nitrogen content and Total Nitrogen content to 5 mg/L and 10 mg/L respectively in treated domestic sewage. The…

Pic: Mayur Channagere If you are someone who rides a bike for more than four hours in Bengaluru every day, there’s a significant chance that you will develop Chronic Obstructive Pulmonary Disease (COPD). COPD, which makes breathing difficult, is a leading cause of disability and death globally; it is irreversible and worsens over time. The conclusion is from a study on 100 non-smokers in Bengaluru aged 25-40 years, who commute to work by bike. Given the worsening traffic jams in the city, the number of people riding bikes for over four hours per day could be quite high. But respiratory…

Bengaluru lets its sewage into valleys, rivers and lakes. Little sewage is processed, while much of it is unprocessed in nature. Navin, a villager from K Channasandra, believes that the Maragondanahalli Lake is the savior for the villagers and their animals. Pic: Perumal Venkatesan Rampura Valley is one of the valley systems of Bengaluru in the north east of the city. This valley gets a mix of treated and untreated water from the raja kaluve (storm water drain) sewage treatment plant, which has 40 MLD capacity and uses Extended Aeration Process. The wastewater from north-eastern parts of Bangalore flows into…

Bangalore, India’s garden city, has slowly become the garbage city - like most major Indian cities and towns. One of the main culprits has been single use disposables like plastic carry bags, plastic and paper cups, plastic and Styrofoam plates, etc. The 'Single Use Plastic Ban campaign' has brought together MLAs and Corporators, BBMP officials, RWAs, citizen groups, activists and social organisations to stop the menace of single use disposables, and implement the waste segregation at source rule in their rspective wards. As of date, more than 20 wards in Bengaluru have already launched this campaign and almost an equal number are in…

I saw this notice in the Arekere Reserve Forest today. What is "illegal dumping"? Is there any "legal dumping"?  And the amount of trash that lies behind the notice gives the lie to the message anyway. What the photograph shows is the apathy we have towards our surroundings... sad to see.

Even as he holds a big fish in his left hand, a young boy tries to reel in another fish. Pic: Ganga Madappa Picture this. A young lad sits on the edge of Ulsoor lake, with a stick in hand. He immerses one end of the stick into the water and moves it through the water. In a matter of seconds, a large fish floats to the edge and the boy picks it up. As he picks up the fish, someone shouts from the crowd, “Ai Appu! What are you doing? Drop it… it’s poisonous! Go wash your hands!” The…

My Dear Friends and Fellow Bengalureans, Warm (or perhaps ‘fiery’) greetings from me. Possibly, I do not need an introduction. Nevertheless, for those who still don’t know me: I’m the disrepute of Bengaluru - the frothy, foamy, toxic-filled, foul-smelling Bellandur Lake, which many claim has put Namma Bengaluru to shame on international landscapes. This would make for a pretty picture if we didn't know the reality. Pic: Sanchayan Nath Let me say, I owe this claim-to-fame to: The city’s mindless administrative machinery Unlawful encroachers All those who consider dumping waste (solid, liquid or industrial) in my waters their birth right!…

I conducted the Campus Bird Count at the Indian Institute of Management, Bangalore, on two days, Saturday, 13th Feb, and Sunday, 14th Feb 2016. I had already mentioned that as birders and naturalists, our team would be carrying their own water bottles, and that IIMB should only provide for filling up the bottles and not set out PET bottles of mineral water. After the count on the morning of the 13th, IIM-B hosted our birding team for breakfast. I noted the small mineral water PET bottles at each place setting and requested the Dean of Administration, Dr G Shainesh, not…
