CPCB raises concern on Pollution and Frothing in Yamuna

CPCB raises concern on Pollution and Frothing in Yamuna
6th December

CPCB has observed froth formation and increase in ammonia levels in river 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 Yamuna.

Monitoring of twenty two drains carried out recently, indicated that fourteen drains (Sonia Vihar, Najafgarh, Shastri Park, Shahdara, etc.) are found untapped, discharging sewage. While five drains are 100% tapped and no flow at downward of interception observed, two drains were found tapped but were overflowing into Yamuna river. 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, CPCB has issued directions to Delhi Jal Board to submit time bound action plan to ensure compliance with norms by STPs and that no untreated sewage is discharged to these drains.
Delhi Pollution Control Committee (DPCC) has been directed to take action against non-complying Common Effluent Treatment Plans (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 concerned agencies to submit action taken report by 15th December, 2020.

CPCB monitors water quality of River Yamuna and drains discharging into the River. However, it is common knowledge that STPs and CETPs often discharge untreated sewage directly into the river to avoid incurring cost. Most of the times, during night the treatment plants are switched off to cut electricity costs and untreated sewage is discharged. If CPCB takes its role seriously without any compromise then the pollution problem can become much less. However, given the past track record of the state as well as central pollution control boards, the common man doesn't expect much. Lets hope this time CPCB is going to discharge its duties most efficiently and in a proactive manner.
