## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI

## ( SHRI RAJ BHUSHAN CHOUDHARY )

(a) The water quality of the Yamuna River at Palla, Nizamuddin Bridge, and Okhla Barrage in Delhi is being  monitored  monthly  by  the  Central  Pollution  Control  Board  (CPCB)  under  the  National  Water Quality Monitoring Programme (NWMP). Since January 2025, data for parameters such as BOD, DO, and Faecal Coliform (FC) are enclosed in Annexure I.

(b)  &  (e) As  per  the  information  provided  by  the  Delhi  Jal  Board  (DJB),  the  estimated  sewage generation in Delhi is 3,596 million litres per day (MLD). The total installed capacity of 37 operational sewage treatment plants (STPs) of DJB is 3,474 MLD. As of June 2025, the capacity utilization of these STPs  was  2,955  MLD  of  which  2,014  MLD  of  treated  sewage   from  23  STPs  complied  with  the discharge standards prescribed by the Delhi Pollution Control Committee (DPCC) and 14 STPs are non-

compliant to DPCC norms. Further, about 641 MLD of sewage remains untreated and enters the river or drainage network, contributing to pollution in the Yamuna.

Further,  the  Central  Pollution  Control  Board  (CPCB)  conducts  annual  inspections  of  Grossly Polluting Industries (GPIs) operating in the Yamuna River basin in NCT-Delhi, which have the potential to  discharge  into  the  Yamuna  and  its  tributaries.  These  inspections  are  carried  out  by  joint  teams comprising  officials  from  technical  institutes  such  as  IITs,  NITs,  and  the  Delhi  Pollution  Control Committee (DPCC)/State Pollution Control Boards (SPCBs)/Pollution Control Committees (PCCs).

During the last inspection conducted by CPCB in 2024, a total of 189 GPIs located along the main stem of the Yamuna River were inspected. It was estimated that these GPIs discharge approximately 1.33 MLD of treated wastewater, carrying a pollution load of 0.046 TPD in terms of BOD.

Out of the 189 GPIs inspected, 158 were found operational, while 31 were self-closed. Among the 158 operational GPIs, 49 were found non-complying with respect to discharge norms or lacked valid consent to operate. These 49 non-complying GPIs were issued directions by the concerned SPCBs/PCCs, including 40 show-cause notices and 9 closure directions.

(c) Under the Namami Gange Programme(NGP) for the rejuvenation of River Yamuna, 9 projects have been sanctioned for the creation of a sewerage treatment capacity of 1,268 MLD at a cost of  ₹ 1,951 crores. All of these projects have been completed. The list of projects is enclosed in Annexure II.

(d) The total funds of ₹ 140 crores have been allocated by NMCG and the Government of NCT of Delhi for Yamuna cleaning since January, 2025; Out of which ₹ 108.31 crores have been utilized.

(f) The cleaning of river is an ongoing process and this Ministry is supplementing the efforts of the States  for  checking  the  rising  level  of  pollution  of  river  Yamuna  by  providing  financial  assistance  to States of Himachal Pradesh, Haryana and Delhi besides Uttar Pradesh.  The various projects aimed at rejuvenation  of  river  Yamuna  are  in  different  stages  of  planning/construction/  completion  and  close monitoring is being done at multiple levels to ensure timely  completion.
