Link between Chembarambakkam pipeline and city's water distribution network to be completed soon
The work to interconnect the pipeline from the Chembarambakkam water treatment plant to the city's water distribution network will be completed in a few days. Residents will get improved water supply from August. Municipal Administration Minister K.N. Nehru inspected the operation of the treatment plant and the ongoing ₹66.78-crore pipeline work on Friday. The pipeline will travel for 11.7 km from Chembarambakkam to Porur and will be interconnected with a network to Tambaram. The second portion of the pipeline will be 9.2 km long and travel from the Poonamallee Bypass Road junction to Koyambedu. Once the trial run is completed in a fortnight, the water supply from Chembarambakkam will be increased from 265 million litres a day (mld) to 530 mld. Residents of various localities, including Anna Nagar, Ambattur, Valasaravakkam, Kodambakkam, Teynampet, Adyar, Tambaram, Kundrathur, and Sriperumbudur, will get improved water supply, a press release said. Mr. Nehru, who also inspected the Minjur desalination plant, instructed officials to prepare a detailed project report to revamp the facility. Chennai's first desalination plant in Kattupalli was established in 2010. However, it became dysfunctional owing to internal issues, including labour unrest and contract termination. The Chennai Metropolitan Water Supply and Sewerage Board will take measures to assess the condition of the plant and increase production to 100 mld. Mr. Nehru also instructed officials to explore the possibility of providing water supply to neighbouring villages. Minister for Minorities Welfare S.M. Nasar and Poonamallee MLA A. Krishnaswamy were among those present. According to a press release, Mr. Nehru on Friday inaugurated a street renamed 'Bishop Ezra Sargunam Road' in ward 100 of Kilpauk. The road where Bishop Ezra Sargunam, the first national leader of the Evangelical Church of India, lived has been renamed in his honour. Mr. Nehru also inspected the construction of the 1,200-m flyover on South Usman Road, being built at a cost o ₹164.92 crore under the Infrastructure and Amenities Fund. He reviewed the gig workers' rest lounge on Prakasam Road, built at a cost of ₹25 lakh. He later inspected the ₹32.62-crore restoration works at Victoria Public Hall being carried out under the Singara Chennai 2.0 project.

No tech to treat ‘forever chemicals' in Chennai waters, NGT told
CHENNAI: Chennai's water bodies may be contaminated with Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), also known as 'forever chemicals', but Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) says there is no mandate nor technology available to treat them, both in drinking water and wastewater. The submission was made by CMWSSB superintending engineer Sivakumar in an affidavit before the Southern Bench of the National Green Tribunal (NGT). The tribunal had registered a suo motu case based on media reports highlighting alarming levels of PFAS in waterbodies, including drinking water sources such as Chembarambakkam lake. A recent study by IIT Madras, published in a scientific journal, found PFAS concentrations in the city's water to be nearly 19,400 times higher than the safety levels set by the US Environmental Protection Agency. The chemicals were detected in groundwater near the Perungudi dumpyard, and in the Adyar river, Buckingham Canal, and Chembarambakkam lake. 'Forever chemicals', due to their persistent nature and strong carbon-fluorine bonds, are widely used in products like non-stick cookware, food packaging, and firefighting foams. When present in drinking water, they pose serious health risks, including links to cancer and liver ailments. A metro water official stated that current treatment facilities are not equipped to remove PFAS due to inadequate infrastructure and limited technical expertise. However, CMWSSB maintains that it meets Indian Standard (IS:10500) requirements for treated water. Sivakumar said the Union Environment Ministry and the Central Pollution Control Board must issue specific guidelines for PFAS regulation. Though advanced PFAS treatment methods are being explored in the US, EU, Australia, and China, their adoption in developing countries remains limited due to high costs and lack of expertise.

CM Stalin unveils 50 automated water dispensing units
CHENNAI: Chief Minister MK Stalin on Wednesday inaugurated 50 automated drinking water dispensing units across Chennai, installed by the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) at a cost of Rs 6.04 crore. The units, set up in high-footfall public areas such as bus terminals, railway and metro stations, government hospitals, markets, parks, temples, schools, and colleges, are intended to provide free and safe drinking water to the public. Users could collect water in 1-litre or 150 ml quantities through the automatic dispensers. However, within hours of the launch, residents and commuters reported that some of the machines had stopped functioning. Social activist LM Jai Ganesh said the units in Vasuki Nagar and Muthamil Nagar near Kodungaiyur became non-operational by Wednesday afternoon. He noted even during the inauguration by MLA RD Sekhar, only the machine at Vasuki Nagar dispensed water, but that too stopped functioning after sometime. 'When food delivery agents and auto drivers tried to fill their bottles, the machines didn't work,' he told TNIE. 'When I contacted the toll-free number displayed on the machine, the person who answered the call said they were unaware of the issue and asked me to call the (CMWSSB) area engineer.' An auto driver in the area, who did not want to be named said, 'I finished my meal nearby and came to drink water, but there was no water.'
