CPCB raises concern over air pollution, frothing in Yamuna

Tribune News Service

New Delhi, December 6

The CPCB, which monitors water quality of Yamuna and drains discharging into it, has raised concerns over pollution and frothing in the river and asked Delhi, Haryana and Uttar Pradesh for effective sewage treatment and sought an action taken report from them by December 15.

According to a CPCB statement, monitoring of 22 drains in Delhi found as many as 14 drains (Sonia Vihar, Najafgarh, Shastri Park, Shahdara, etc.) “untapped, discharging sewage”.

In the past, CPCB observed froth formation and increase in ammonia levels in Yamuna because of discharge of untreated sewage, non-operation of existing Sewage Treatment Plants, improper functioning of Effluent Treatment Plants(ETPs) installed by the industries and Common Effluent Treatment Plants(CETPs) located on the banks of river.

While five drains are 100% tapped and no flow at downward of interception observed, two drains were found tapped but overflow into Yamuna was observed. One drain (drain no. 14) has no flow at all. Due to partially/untreated discharge of sewage and industrial effluent containing phosphorus, many times, foaming also is observed. 

Taking cognizance of this, the CPCB issued directions to Delhi Jal Board to submit time-bound action plan to ensure compliance to norms by STPs and that no untreated sewage is discharged to these drains, the official statement said. 

The Delhi Pollution Control Committee (DPCC) has been directed to take action against non-complying Common Effluent Treatment Plants (CETPs) and industrial units. Similar directions have also been issued to State Pollution Control Boards of Haryana and Uttar Pradesh. In view of the importance of the issues, reminders have been issued today to agencies concerned to submit action taken report by December 15.
