## ANSWER THE MINISTER OF STATE FOR JAL SHAKTI

## (SHRI BISHWESWAR TUDU)

(a)   to  (d)    It  is  the  responsibility  of  the  States/Union  Territories  (UTs)  and  Local Bodies to ensure required treatment  of  sewage  to  the  prescribed  norms  before  discharging  into  rivers  and  other  water  bodies,  coastal waters or land to prevent and control of pollution therein. As per the report of Central Pollution Control Board (CPCB) of March 2021, 72,368 million litres per day (mld) of sewage is generated from urban areas in the country,  against  which  1469  nos.  Sewage  Treatment  Plants  (STPs)  of  31,841  mld  treatment  capacity  are available. State/UT wise details of number of sewage treatment plants (STPs) are at Annexure-I .

As per the CPCB Report of March 2021, there are 38 STPs in Delhi, out of which 3 STPs are nonoperational. Department of Environment, Govt. of National Capital Territory (NCT) of Delhi has informed that 28 STPs were found complying with design parameters based on value of Biochemical Oxygen Demand (BOD) and  Total  Suspended  Solid  (TSS).  8  STPs  were  found  to  be  compliant  with  respect  to  stringent  standards prescribed by Delhi Pollution Control Committee (DPCC) based on value of BOD and TSS ≤ 10 milligram per litre (mg/l). DPCC is also conducting periodic sampling of major drains (24 nos.) outfalling in river Yamuna and at various locations (8 nos.) in the stretch of river Yamuna.

CPCB in association with various State Pollution Control Boards/Committees have been monitoring the water quality of rivers and other water bodies across the country through a network of monitoring stations under  the  National  Water  Quality  Monitoring  Programme.  As  per  the  last  report  published  by  CPCB  in September 2018, 351 polluted stretches have been identified on 323 rivers in the country based on monitoring results in terms of Bio-chemical Oxygen Demand (BOD), an indicator of organic pollution, which includes the Delhi stretch of river Yamuna as per details given below:

| River   | Polluted river stretch     | Priority (BOD value range)         | BOD Range (mg/l)   |
|---------|----------------------------|------------------------------------|--------------------|
| Yamuna  | Along Wazirabad to Asagpur | Priority I (BOD exceeding 30 mg/l) | 9-80               |

For  conservation  of  rivers,  this  Ministry  has  been  supplementing  the  efforts  of  the  States/UTs  by providing financial and technical assistance for abatement of pollution in identified stretches of rivers in the country  through  the  Central  Sector  Scheme  of  Namami Gange  for  rivers  in  Ganga  basin,  and  Centrally Sponsored Scheme of National River Conservation Plan (NRCP) for other rivers. NRCP has so far covered polluted stretches on 34 rivers in 77 towns spread over 16 States in the country with the project sanctioned cost of Rs.5961.75 crore, and inter-alia , a sewage treatment capacity of 2677 mld has been created. Under the Namami Gange programme, a total of 353 projects, including 157 projects for sewage treatment of 4952 mld and a sewer network of 5212 kms, have been sanctioned at a cost of Rs.30458 crore.

Operation & Maintenance is the responsibility of State/UT Governments and the Local Bodies. Upgradation and optimal operation of STPs is a continuous process and is attended to by them, as and when required.  Such  up-gradation  is  also  taken  up  under  NRCP  and  Namami  Gange  programme.  10  sewage treatment  infrastructure  projects  at  an  estimated  cost  of  Rs.  2296  crore  have  been  sanctioned  under  the Namami Gange programme for creation/upgradation of the 1362 mld of sewage treatment capacity in Delhi.

CPCB  has  issued  directions  on  21.01.2015  to  the  SPCBs/PCCs   under  the  Water  (Prevention  & Control  of Pollution),  Act  1974  to  issue  directions to Local  Authorities  responsible  for  sewerage management in respective cities/towns and to submit time bound action plans for collection, transportation and treatment of sewage generated in urban areas. CPCB has also issued directions on 09.10.2015 to Local Authorities  under  the  Environment  (Protection)  Act,  1986  for  sewage  management  in  Class  I  Cities  and Class II towns to ensure treated wastewater is disposed in accordance with the stipulated standards.

Besides,  in  compliance  of  the  orders  of  National  Green  Tribunal  (NGT)  in  Original  Application No.673/2018 regarding rejuvenation of polluted  river  stretches  in  the  country,  States/UTs  are  required  to implement approved action plans, including setting up/upgradation of STPs, for restoration of the polluted stretches  in  their  jurisdiction  as  identified  by  CPCB  and  published  in  their  report  of  2018,  within  the stipulated  timelines.  As  per  the  orders  of  NGT,  regular  review  on  implementation  of  action  plans  is undertaken in the States/UTs and also at Central level.
