## Capacity of Sewage Treatment Plants

## 2558. SHRI NAVEEN JINDAL:

Will the Minister of ENVIRONMENT, FOREST AND CLIMATE CHANGE be pleased to state:

- (a) the total quantity of sewage generated daily in the country, vis-a-vis installed capacity of Sewage Treatment Plants (STPs), State/UT-wise;
- (b) the total operationalised capacity of STPs in the country, State/UT-wise;
- (c) whether certain States/UTs do not have sufficient number of STPs and if so, the reasons therefor; and
- (d) the  remedial  steps  taken/being  taken  by  the  Government  to  maximise  treatment  of sewage and reuse of treated water along with the result thereof?

## ANSWER

MINISTER  OF  STATE  IN  THE  MINISTRY  OF  ENVIRONMENT,  FOREST  AND CLIMATE CHANGE (SHRI KIRTI VARDHAN SINGH)

(a) to (d)

Central  Pollution  Control  Board  (CPCB)  carried  out  inventorization  of  Sewage  Treatment Plants (STPs) for the year 2020 with the help of State Pollution Control Boards (SPCBs) / Pollution Control Committees (PCCs) of Union Territories & Local Bodies and prepared report titled  'National  Inventory  of  Sewage  Treatment  Plants  in  India-2021'.The  state-wise assessment of the sewage generation, installed capacity for sewage treatment and operational treatment capacity in urban centres across the country is attached as Annexure-I.

The remedial steps taken/being taken by the Government to maximise treatment of sewage and reuse of treated water are as below:

- CPCB directed  all  SPCBs/PCCs  under  Section  18(1)(b)  of  The  Water  (Prevention  & Control of Pollution) Act, 1974 to direct concerned agencies in the State/UT to develop infrastructure for sewage treatment.
- CPCB issued directions under Section 5 of The Environment (Protection) Act, 1986 to Municipal Corporations of 46 Metropolitan cities and 20 State Capitals for Treatment and Utilization of Sewage for Restoration of Water Quality of River.
- CPCB issued directions under section 18 (1) (b) of the Water (Prevention and Control of Pollution), Act, 1974 to all SPCBs/PCCs for installation of Online Continuous Effluent Monitoring System (OCEMS) for self-surveillance of Sewage Treatment Plants.

In addition, sewerage  infrastructure  is  created  under  programs  like  Atal  Mission  for Rejuvenation & Urban Transformation (AMRUT) and Smart Cities Mission of Ministry of Housing & Urban Affairs. Under AMRUT, 890 sewerage/ septage management projects worth ₹34,505 crore have been grounded through which 4,447 Million Litre per Day (MLD) sewage treatment capacity (new/augmented) has been created of which 1,437 MLD capacity has been developed for recycle/reuse.

Under  AMRUT  2.0,  592  sewerage/septage  projects  worth  ₹67,607.67  crore  have  been approved by Ministry of Housing and Urban Affairs (MoHUA) so far. Approved projects cover 6,739  MLD  sewage  treatment  capacity  (new/augmentation)  of  which  2,093  MLD  sewage treatment capacity is for recycle/reuse.

MoHUA has also launched "Jal Hi AMRIT" initiative under AMRUT 2.0 reforms, which aims to incentivize States and Union Territories (UTs) to efficiently manage sewage treatment plants for recyclable treated water meeting environmental standards on sustained basis. The focus of this  initiative  is  to  build  capacity  and  incentivizing  qualitative  improvements  in  the  treated discharge effluent. This initiative is targeted to create opportunities for suitable reuse of water, contributing to the overall goal of water security through increasing water availability under the Mission.
