## ANSWER

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

- (a)  to (c) 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). The State-wise details of sewage generation from urban areas and corresponding sewage treatment capacity available are at Annexure.

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 32 rivers in 76 towns spread over 14 States in the country at a sanctioned cost of Rs. 4581.91 crore, and Central share of Rs.2258.73 crore has been released to the State Governments for implementation of various pollution abatement schemes. Sewage treatment capacity of 2472.43 mld has been created so far under NRCP. It is emphasized that the treated effluent from the sewage treatment plants (STPs)  constructed  under  NRCP  is  reused  in  agriculture,  industry  and  for  other  purposes, wherever feasible.

O.I.H.

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.
