New Delhi: In what appears to be a mismanagement of Delhi Jal Board (DJB), untreated sewage water is being disposed off in the river as it does not reach to sewer treatment plants for recycling despite huge money being spent on the cleaning Yamuna.  

As per the DJB report, Delhi’s 20 sewer treatment plants have recycling capacity of 544 million gallon daily (MGD), but they are recycling only 350 MGD of sewage water. However, Delhi’s total sewage water stands at 650 MGD.

The national capital is also going to commission three more sewage plants, increasing the total recycling capacity to 650 MGD. It clearly reflects that presently untreated sewage water is being disposed off in the Yamuna.

According to the Central Pollution Control Board, Bio-Oxygen Demand (BOD) level should not exceed to three mg per litre. But, the DJB data says that recycled water from treatment plants contains 15-20 percent of BOD level which is not useful for irrigation.  

A top DJB official informed that the recycling capacity has been fixed at 10 BOD for the new sewer treatment plants being constructed in the third phase of Yamuna Action Plan.    

Sewage line is being laid to reach the sewage water in the plants where the level of sewage water is checked in the laboratories. NGO, Citizens Front for Water Democracy said that the laboratories remain open from 9 am to 5 pm, while plants recycle the sewage water 24x7.
