## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI & SOCIAL JUSTICE AND EMPOWERMENT

## (SHRI RATTAN LAL KATARIA )

- (a): Central Pollution Control Board (CPCB) have informed that based on water quality monito river Ganga being carried out for pre as well as lockdown period and studies conducted by the Pollution Control Boards (SPCBs) and other agencies to assess the impact of lockdown on t quality of river Ganga and its tributaries, it has been observed th at no d finite trend exists in differe water quality parameters observed  for various stretches of river Ganga  and its tributarie varying degrees of improvement in a few water quality parameters have been observed as per CP SPCB reports w hich may be attributed to various factors such as increased availability of f due to rainfall in the river catchment, no industrial effluent discharge and reduced human as restriction on bathing, ritual disposal, restricted tourism, solid waste, mass washing of clothes etc.
- (b): The strategy during lockdown has been to ensure that all the sewage treatment plants c function  without  any  interruption  as  sewage  generation  and  its  contribution  to  pollutio constant ev n though pollution due to industrial effluent and solid waste generation atghatsgot

controlled  due  to  restrictionsduring the  lockdown.  Guidelines  were  issued  to  follow  all  safe precautions  while  continuing  the  operation  of  STPs.  The  various  interventions  for  abat pollutions of rivers have been continued. Some of them are given below:

- Financial assistance is being provided to States for setting up of sewage infrastructure a other pollution abatement activities under Namami Gange and National River Conservation Plan (NRCP) of ministry of Jal Shakti as well as AMRUT & Smart Cities Mission of Ministry of housing & Ur ban Affairs.
- State Government have formulated river action plans to restore water quality of po river  stretchesfor  intercepting,  diverting  and  treatment  of  municipal  wastewater urban centres.
- Regulation of industrial Pollution is implemented thr ough various provisions of Water (Prevention  and  Control  of  Pollution)  Act,  1974  under  Consent  mechanism  by  th respective  State  Pollution  Control  Board  (SPCB)  and  Pollution  Control  Committee (PCC).
- The  Online  Continuous  Effluent  Monitoring  Systems  (OCEMS )  are  installed  by  17 -categories  of  industries  and  Grossly  Polluting  Industries  (GPIs)  being  establish industrial units in the country through the directives issued by CPCB for getting r information on the effluent quality and non - complying u nits were identified and actions were taken against these units.

(c): Provision of Environment (Protection) Act, 1986 does not permit discharge of untreated ef or waste into the environment. In view of non - availability of adequate infrastructure and improper management, presently, untreated sewage and polluting waste is reaching river bodies.

Under the Namami Gange Programme, CPCB under ' Pollution, Inventorization, Assessment & Surveillance (PIAS)' Project has identified priority drains responsible f or carrying sewage, industrial wastes  and  agriculture  run - off  etc  into  river  Ganga.    These  drains  are  being  monitored  on  ha yearly - basis.  Out of a total of 151 priority drains, flows from 145 drains will be covered their interception and diversi on or sewer network for treatment through 113 sewerage projects taken on main stem of Ganga under Namami Gange Programme for creation of 2171 MLD capacity.  As per the latest monitoring carried out during 2019 (post - monsoon, 2019), the available status of flow and organic load (BOD load) discharging into river Ganga is mentioned in Annexure - I .

Similarly,  1270  MLD  of  treatment  capacity  has  been  created  under  the  YAP  Phase -I  &  II projects on river Yamuna in States of Haryana, Delhi & Uttar Pradesh for it s conservation.  Besides. Government of India / NMCG has sanctioned 24 projects in Himachal Pradesh, Haryana, Delhi and Uttar Pradesh under Namami Gange Programme to abate pollution load to river Yamuna which wil create 1310.6 MLD STP capacity and rehabil itate 528.18 MLD STP capacity.  Two projects have been completed in Sonipat and Panipat creating STP capacity of total 70 MLD and rehabilitat 75 MLD STPs.

As per CPCB data, sewage generation in Delhi is 4420 MLD whereas, total sewage treatme capac ity developed is 3104 MLD and capacity utilization is 2753 MLD, thereby leading to untre sewage discharge of 1667 MLD into river Yamuna. Therefore, it can be stated that dischar untreated and partially treated sewage along the river & industrial w astewater discharges through 23

drains are the main sources of pollution of river Yamuna in Delhi. Water quality of drains period 2015 - 2020 is attached as Annexure - II .

(d) & (e): Cleaning of river is a continuous process and Government of India is supplementing the efforts of the State Governments in addressing the challenges of pollution of rivers by p financial and technical assistance. Assistance is provided to State Governments for abate pollution in identified stretches of vario us rivers (excluding river Ganga and its tributaries) under t Centrally Sponsored Scheme of National River Conservation Plan (NRCP) on cost sharing bas between the Central & State Governments for taking up various pollution abatement works rel tointerception & diversion of raw sewage, construction of sewerage systems, setting up of treatment plants, low cost sanitation, river front/bathing ghat development, etc. The NRCP h covered  polluted  stretches  of  34  rivers  in  77  towns  spread over  16  States  in  the  country  with  a sanctioned cost of Rs. 5870.54 crore. A Central share of Rs. 2530.63 crore has been release State Governments for implementation of various pollution abatement schemes Sewage treatme capacity of 2522.03 millio n litres per day (mid) has been created under the programme.

Under the Namami Gange, for  conservation  and  pollution  abatement  of  the  River  Ganga  and  it tributaries, a total of 315 projects have been sanctioned at a cost of Rs 28,854 Crore . The projects are sanctioned  for  various  activities  such  as  sewerage  infrastructure,  industrial  pollution Ghats & Crematoria, River Front Development, River Surface Cleaning, Institutional Developme Biodiversity Conservation, Afforestation, Rural Sanitation etc.  132 projects have been completed, including 54 sewerage infrastructure projects till July, 2020. Under sewerage projects 668. sewage  treatment  capacity  has  been  added  and  120  MLD  treatment  capacity  rehabilitated. expenditure of  Rs.9370.09  crore  has  been  incurred  by  NMCG  through  various  implementing agencies since its inception in 2011 - 12 for various project activities.

As a result of multi sectoral interventions, the improving trend in water quality of river been  o bserved  based  on  various  parameters  for  measuring  water  quality  viz. Dissolved  Oxygen (DO),  Biochemical  Oxygen  Demand  (BOD)  and  Faecal  Coliform  (FC)  which  have  shown improvements during 2020 -Jan to April (Median) as compared to 2014 (Median) for 51 locati onsas detailed below: -

- DO (Median) has improved at 49 locations (51 locations compared)
- BOD (Median) has been improved at 42 locations (51 locations compared)
- FC (Median) has been improved at 27 locations (43 locations compared)

An improvement in terms of BOD compliance has also been observed in 2020 as compared to 2014 in the following stretch/locations.

- After confluence(A/c) Song (Raiwala) to Haridwar Down Stream (D/s), Uttarakhand
- Narora,  Kannauj  D/s,  Up  Stream  (U/s)  Kanpur,  Prayagraj  (Rasoolabad),  Ka daghat (Prayagraj) and Prayagraj D/s (Sangam), UP
- Nabadwip and Diamond Harbour, West Bengal
