(c)   the efforts taken by the Government to augment waste water treatment capacity and promote reuse of waste water after treatment;

- (d)      whether  most  of  the  sewage  treatment  plants  in  operation  across  the  country  are obsolete and are suitable for treating only the biological and not the chemical components of waste water; and
- (e)      if  so,  the  details  thereof  and  efforts  taken/planned  to  upgrade  the  water  treatment technology in the existing plants?

## ANSWER

MINISTER OF STATE IN THE MINISTRY OF ENVIRONMENT, FOREST AND CLIMATE CHANGE (DR. MAHESH SHARMA)

- (a)  & (b) As per a report published by Central Pollution Control Board (CPCB) in March, 2015, the sewage generation from urban areas in the country is estimated at 61,948 million litres per day (mld), against which the available sewage treatment capacity is only 23,277 mld (37% of the sewage generation) in 816 sewage treatment plants (including 145 sewage treatment  plants  under  construction),  primarily  due  to  lack  of  necessary  investments  and prioritization. The State-wise details of sewage  generation from urban areas and corresponding sewage treatment capacity available are at Annexure.
- (c) This  Ministry  has  been  supplementing  the  efforts  of  the  State  Governments  in abatement  of  pollution  in  identified  stretches  of  various  rivers  under  the  National  River Conservation  Plan  (NRCP),  on  cost  sharing  basis  between  the  Central  and  State Governments. NRCP has so far covered polluted stretches of 31 rivers in 75 towns spread over 14 States in the country at a sanctioned cost of Rs. 4579.56 crore, and Central share of  Rs. 2236.98 crore has been released to the State Governments for implementation of

various pollution abatement schemes. Sewage treatment capacity of 2466.43 mld has been created so far under the NRCP. It is emphasized that the treated effluent from the sewage treatment  plants  (STPs)  constructed  under  NRCP  is  reused  in  agriculture,  industry  and other purposes, wherever feasible.

Further,  to  ensure proper  treatment  of municipal  wastewater  before  discharge  into the rivers & other water bodies, CPCB has issued directions under Section 18 1(b) of the Water (Prevention and Control of Pollution) Act, 1974 in April, 2015 to all the State Pollution Control Boards (SPCBs)/Pollution Control Committees (PCCs) in the country for setting up of  STPs  in  their  respective  States.  CPCB  also  issued  directions  in  October,  2015  to municipal authorities of 184 towns (66 metropolitan cities and State capitals + towns along river  Ganga) under Section 5 of the Environment (Protection) Act, 1986 to ensure proper treatment and disposal of sewage generated for abatement of pollution of rivers.

(d) & (e) The STPs are designed to reduce Chemical Oxygen Demand (COD), Biochemical Oxygen  Demand  (BOD)  and  Suspended  Solids  in  sewage.  Central  Government  has  in October, 2017 revised the general discharge standards for STPs, which have been made more  stringent  and  also  now  includes  the  parameter  of  fecal  coliform.  The  revised standards shall applicable to all STPs to be commissioned on or after the 1st June, 2019 and the old/existing STPs shall need to be upgraded to achieve these standards within a period of five years from date of publication of notification dated 13.10.2017.
