Nearly 700 km of Karnataka rivers polluted; cities, towns depend on contaminated water
Shivamogga: A total of 693.75 of river stretches across Karnataka are polluted, and water from several of these rivers is being supplied to towns and cities, the State government informed the Legislative Assembly.
According to a report published by The New Indian Express on Monday, replying to an unstarred question by Thirthahalli MLA Araga Jnanendra during the winter session in Belagavi, Forest, Environment and Biodiversity Minister Eshwar Khandre said rivers are classified into five categories, P1 to P5, based on Biochemical Oxygen Demand (BOD) levels, with P1 being the most polluted.
He reportedly said untreated domestic wastewater from urban and rural areas is the main reason for river pollution. Arkavati, Lakshana Teertha, Tungabhadra, Bhadra, Tunga, Cauvery, Kabini, Kagina, Krishna, Shimsha, Bheema and Netravati are the polluted rivers and so far, 112 polluted drainages along these rivers have been identified.
Khandre explained that rivers are classified into five pollution categories P1 to P5. The Arkavati River has been placed in the P1 category, while no rivers fall under P2 and P3. Tungabhadra, Bhadra and Shimsha are categorised under P4, and eight other rivers fall under P5.
Khandre allegedly said domestic wastewater from municipalities, towns and villages along riverbeds is being discharged into at least 17 rivers, identified by the Central Pollution Control Board (CPCB). This is the primary cause of river pollution.
According to the report, the minister said drinking water is being supplied from polluted rivers in districts such as Mandya, Ramanagara, Vijayapura and Shivamogga. In parts of Uttara Kannada, Ballari, Vijayanagara and Bagalkot, local bodies are also drawing water from polluted river sources.
In 2022-23, CPCB identified South Pinakini, Aghanashini, Sharavathi and Gangavali rivers too as polluted. But wrote to CPCB, stating that these rivers are not polluted and sought their removal from the list. An action plan is being prepared for the South Pinakini River, he said.
On remedial measures, Khandre reportedly said the Karnataka State Pollution Control Board is setting up sewage treatment plants as per the directions of National Green Tribunal.
As per the report, under 12 river rejuvenation plans, the state generates 817.31 million litres per day (MLD) of sewage. While 41 STPs with a capacity of 614.1 MLD are operational, 203.21 MLD of sewage remains untreated.
Work is underway to establish 19 STPs with a capacity of 248.91 MLD, while 39 more STPs with a combined capacity of 357.92 MLD are in the planning stage. Progress is being monitored and reported regularly to the NGT and the Union Ministry of Jal Shakti.
The minister reportedly said the state government gave its approval for underground drainage works worth Rs 535.56 crore in 2021 for 24 cities/towns besides Rs 523.80 crore for nine UGD projects.

Bombay HC to form high-powered committee on Mumbai air pollution
Mumbai (PTI): The Bombay High Court on Thursday said it would form a high-powered committee to oversee the compliance of measures to tackle air pollution in the Mumbai region, noting that the efforts taken so far by state and civic authorities are insufficient.
It was not criticizing anyone but wanted to ensure that "people should live in pure air," said a division bench led by Chief Justice Shree Chandrashekhar.
The HC had in October 2023 taken suo motu cognizance of the rising pollution in the metropolis "which was ranging between good, satisfactory, moderate poor, very poor and severe", the bench noted.
Directions were issued by the court on November 6, 2023, and suggestions were made for short-term, mid-term and long-term measures.
Since then, the HC has made observations expressing dissatisfaction about the steps taken by the Mumbai and Navi Mumbai civic bodies, the judges said.
The Maharashtra Pollution Control Board (MPCB) is simply "sailing on its affidavits," but the steps purportedly taken by it were not sufficient, the court stated.
Air pollution in Mumbai has not decreased, in fact it was reported to be very severe in December, said the judges.
"We have apprised ourselves of the previous orders, and find that compliances so far made by (municipal) corporations and MPCB are not sufficient and satisfactory," the court said.
The authorities might have taken serious steps but their results were not visible, it added.
The court expressed inability to examine all the affidavits filed by the municipal corporations and MPCB and reports submitted by an expert committee (formed in 2023), citing the "rising number of dockets and limited hours and time."
After hearing all the parties at length, the high court decided to form a high-powered committee led by a former Supreme Court judge to monitor the compliance of measures to tackle air pollution in Mumbai and the surrounding areas.
The committee should meet on a daily basis, the court said, adding that its members should be provided necessary facilities.
The bench also referred to a suggestion that the citizens affected by pollution should be compensated.
The lawyer for the Navi Mumbai Municipal Corporation said there are existing statutory bodies to look into this aspect.
"Maybe there are statutory bodies formed in Maharashtra, but then we have not come across any suggestion or action taken by such a body in the present proceedings..." the court said, adding that it was inclined to give "some powers" to the committee.
The court is expected to finalize the names of the committee members in its written order.
