‘2% of Yamuna to blame for 76% of its ills’

  • | Monday | 10th December, 2018

This 2% stretch from Wazirabad to Okhla sees maximum discharge of untreated industrial and domestic wastes.The committee has suggested that a team of scientists be formed from CPCB, DPCC and other institutions like IIT Delhi or NEERI to carry out inspections and submit reports to it for remedial action. The team can look into the risks and benefits of an alternative way of routing the same quantity of water which can help in reducing the pollution level, it said.The committee has also recommended a mechanism to be worked out jointly with DPCC and CPCB to install an online system for quality testing of water in Yamuna at Palla and Wazirabad.“Not only standard parameters would be included but also ammonia because this is brought up as a recurrent problem which impacts drinking water supply to Delhi,” it said.The monitoring committee also raised objection to the capacity utilisation of common effluent treatment plant (CETP) which is as low as 25%.Another area of concern is the direct discharge of completely unregulated waste from industries and residences into the river.“The industrial pollutants when mixed with domestic sewage are not amendable to treatment even by the STPs due to limitation of treatment technology,” the committee rued. NEW DELHI: A small stretch of less than 2% of the Yamuna accounts for 76% of the river’s pollution, according to a monitoring committee overseeing its cleaning.The committee has further said that the river is “fighting to stay alive” and it would not be possible to rejuvenate the Yamuna unless minimum environmental flow is provided as it is “virtually reduced to a trickle and remains dry in some stretches for almost nine months of the year”.National Green Tribunal Chairperson Justice A K Goel had in July formed the monitoring committee comprising retired expert member B S Sajwan and former Delhi chief secretary Shailaja Chandra and directed them to the submit an action plan and detailed report on cleaning of the river by December 31.The committee has submitted the details to the Delhi government.In the action plan, it is mentioned that “Although the Yamuna river flows only for 54 kilometres from Palla to Badarpur through Delhi, the 22 kilometre stretch from Wazirabad to Okhla, which is less than 2% of the river length of 1370 kilometres from Yamunotri to Allahabad, accounts for about 76% of the pollution in the river”.
