## (SHRI RATTAN LAL KATARIA )

(a)to (d)  Discharge of untreated & partially treated sewage and industrial effluent is p pollution  of  river  and  water  bodies.      As  per  the  report  published  by  Central  pollution (CPCB) in March, 2015; sewage generation from ur ban areas in the country is estimated at 61, 948 m litres per day (mld), against which available sewage treatment capacity was 23,277 mld. Thi proposed sewage treatment plants (STPs) also and operational capacity of sewage treatment ts was found  to  be  18,883  mld.  The  State/  UT - wise  details  of  sewage  generation  from  urban  areas corresponding sewage treatment capacity available in accordance with the report, are given at Annexure .

Discharge of raw sewage into water bodies cause de pletion of Dissolved Oxygen (DO) in river an thus, adversely impact aquatic life. Cleaning of river through proper sewage management is process  and  Central  Government  is  supplementing  the  efforts  of  the  State  Governments  a Territories in  addressing  the  challenges  of  pollution  of  rivers  by  providing  financial  a assistance throughschemes likeNationalRiver Conservation Plan (NRCP) and Namami Gange. The

NRCP has so far covered polluted stretches of 34 rivers in 77 towns spread over 16 States with a sanctioned cost of Rs. 5870.54 crore. Under Namami Gange, the rejuvenation of Gan tributaries have been taken up. So far, a total of 3 10 projects have been sanctio ned at an estimated cost of Rs. 28790.66  crore  under  Namami  Gange.  Of  these,  116  projects  have  been  completed  and operational.

In  addition,  sewage  infrastructure  are  also  created  under  programs  like  Atal  M Rejuvenation & Urban Transformation (AMRUT) and Smart cities Mission.

(e) & (f) Operation and maintenance (O&M) of STP and sewage pumping station is the responsibi the State Governments/Urban local body concerned. Lack of adequate sewer networks & hous e connection and unsatisfactory operation and maintenance are major reasons for under utilization of sew plants (STPs). Central Government has been regularly asking the States to improve the per STPs.

In  addition,  CPCB  had  i ssued  directions  on  21.04.2015  to  the  State  Pollution  Control (SPCBs)/Pollution Control Committees (PCCs) under the Water (Prevention and Control of Pollu 1974  asking  them  to  issue  directions  to  Local  Authorities  responsible  for  sewage  man agement  in  their respective cities/towns and to submit time bound action plans for collection, transportation sewage generated in urban area. CPCB has also issued directions on 09.10.2015 to Local Autho Environment (Protection) Act, 1986 for sewage management in Class I Cities and Class II towns an them  to  ensure  that  treated  waste  water  is  disposed  in  rivers  and  water  bodies  in  accor stipulated standards.
