bangalore sewage treatment problem

Bengaluru’s water supply is met either by pipelines that draw water from the Cauvery river several kilometers away, or by pipelines that are sunk several feet underground. It wasn’t always like this. In the past, Bengaluru’s water needs were quenched by the many lakes built across the city. Lake water was used for drinking, agriculture, washing cattle and other purposes. But in recent years, the city’s lakes have become infamous for catching fire, frothing, and becoming dump sites. Many lakes are heavily polluted as the city’s sewage, industrial contaminants and untreated wastewater enter them via stormwater drains, rendering them unusable.…

Due to rapid urbanisation and unplanned development, Bengaluru’s groundwater is getting increasingly contaminated. This issue requires urgent attention as approximately 40% of the city's population depend on groundwater (borewells, open wells and tankers) for their daily water needs such as drinking, cooking and bathing.  Contaminated groundwater could lead to health issues if it is directly consumed. If used for agricultural purposes, it could even enter the food chain.  Residents across the city have reported that borewells discharge coloured or smelly water. This indicates percolation of sewage and chemicals into the water table. Discolouration, cloudiness and bad odour are some of…

The Honourable National Green Tribunal (NGT) of India, constituted under the NGT Act of 2010, bases all its directions and judgements on three basic tenets: Sustainable development Precautionary principle Polluter pays These tenets are considered the bedrock of jurisprudence in cases relating to the environment. I have absolutely no quarrel with any of these guiding principles. I have a question, however, on how the Hon. NGT defines and decides who the real polluter is, in case of dysfunctional sewage treatment plants (STPs) in apartments. Based on NGT's directions, the State Pollution Control Board (KSPCB) has been issuing notices to apartments for running…

In the last couple of months, many apartment complexes in Bengaluru got notices from the state Pollution Control Board (KSPCB), asking them to pay a penalty of Rs 5 lakh, for discharging untreated sewage outside their premises. Many of these apartments were already running Sewage Treatment Plants (STPs), and these were functioning well as per routine lab tests that the apartments used to get done. So, the apartments wrote to KSPCB instead of paying up. But the Board did not respond to the residents’ concerns. Instead, it issued them a ‘show cause’ notice, mentioning that they hadn’t paid the fines…

Solving their civic-woes has been a challenge for the 12 lakh residents living in the 110 villages on the outer circle in the Bruhat Bengaluru Mahanagara Palike (BBMP) limits, in Bengaluru. Not only has the struggle to get drinking-water been unfruitful, the lack of drainage network lets the sewage accumulate in open drains and lakes, causing irreversible long-term ecological and health problems. There is, however, about to be a slight change in their plight. The infrastructural work to lay underground drainage facilities in the five zones — Mahadevapura, Byatarayanapura, Bommanahalli, Dasarahalli and RR Nagar — officially commenced on March 15,…

It’s been a protracted battle that lasted for over 15 months, involving lakhs of apartment residents, thousands of apartment complexes, hundreds of representations to Government and Bengaluru Water Supply and Sewerage Board (BWSSB), tens of court cases and one protest rally. The Government of Karnataka has finally made BWSSB withdraw the retrospective Sewage Treatment Plant (STP) notification imposed on apartments, based on a presentation done by the Governing Council of Bangalore Apartments’ Federation (BAF). During this period, apartment residents have been unreasonably and unfairly accused of not doing their bit for the city, by “opposing STPs”. To clear up the…
