## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI (SHRI V. SOMANNA)

(a)  to  (e)  Drinking  Water  being  a  State  subject,  the  responsibility  of  Planning,  Designing, Approval,  Implementation,  Operation  &  Maintenance  of  drinking  water  supply  schemes, replacement of drinking water infrastructure including cleaning, flushing and repair of pipelines, monitoring of water quality, and oversight of drainage and sewerage systems for both rural and urban  areas  including  those  under  the  Jal  Jeevan  Mission  (JJM),  is  vested  with  State/UT Governments. The Government of India supplements the efforts of the States/ UTs by providing financial, policy guidance and technical assistance.

Jal Jeevan Mission is under implementation since August, 2019, to make provision of tap water supply  to  every  rural  household.  Under  JJM,  as  per  existing  guidelines,  Bureau  of  Indian Standards' BIS:10500 standards are adopted as benchmark for quality of water being supplied through the piped water supply schemes. As per the Operational Guidelines, States/ UTs can utilize

up  to  2%  of  their  annual  allocation  of  funds  under  JJM  for  Water  Quality  Monitoring  & Surveillance (WQM&S) activities, inter-alia, which includes setting up and strengthening of water quality  testing  laboratories,  procurement  of  equipment,  instruments,  chemicals,  glassware, consumables, hiring of skilled manpower, surveillance by community using field test kits (FTKs), awareness  generation,  educational  programmes  on  water  quality,  accreditation/recognition  of laboratories, etc.

Based  on  the  information  received  from  the  State  Government  of  Madhya  Pradesh  as  of 22.01.2026 no rural areas were reported with sewage contamination in drinking water supplies.

In  consultation with various stakeholders 'Concise Handbook for Monitoring Water Quality of Piped  Drinking  Water  Supply  to  Rural  Households'  has  been  released  in  December  2024  for guidance to States/ UT's. This handbook recommended for a comprehensive testing of drinking water samples at various testing points such as source, treatment plant, storage and distribution points, and remedial action wherever necessary including measures such as cleaning of OHTs, check pipe line leakage, etc. to ensure that the water supplied to households is of prescribed quality and to enhance public health.

Under  JJM,  to  enable  the  States/  UTs  for  online  reporting  of  water  quality  monitoring  and surveillance including test reports of water samples for water quality, sample collection etc. for drinking water, an online JJM - Water Quality Management Information System (WQMIS) portal has also been developed. The State-wise details of water quality test reported through WQMIS are available in public domain and can be accessed at: https://ejalshakti.gov.in/WQMIS/Main/report  .  The  State-wise  details  of  water  quality  testing reported by States/UTs on JJM-WQMIS is at annex-I . The district-wise details of water quality testing reported by Maharashtra is at Annex-II .

Further,  Ministry  of  Housing  and  Urban  Affairs  (MoHUA)  has  informed  that  MoHUA supplements  the  efforts  of  States  through  policy  guidance,  financial  support  and  technical advisories under missions and schemes such as AMRUT and AMRUT 2.0 in urban areas. These missions support infrastructure strengthening, including replacement of legacy systems, promotion of 24×7 water supply with quality assurance, Drink from Tap (DfT) initiatives, online water quality monitoring, SCADA-based  monitoring, community  participation, and enhanced last-mile connectivity. Under AMRUT/AMRUT 2.0 and in convergence with States, 246 lakh urban water tap connections, and 182 lakh sewer connections have been provided, while 93,457.51 km of water pipelines and 26,995.61 km of sewer networks have been laid or replaced.

As informed by the State Government of Madhya Pradesh, incidents of vomiting and diarrhoea were reported on 28.12.2025 in Bhagirathpura area (Ward No. 11, Zone-4, Assembly Constituency Indore), resulting in 22 reported deaths due to acute diarrheal disease and hospitalization of 459 persons. The State Government provided ex-gratia assistance of ₹2 lakh to the dependents of each deceased  and  ensured  free  medical  treatment  to  affected  persons  in  Government  and  private hospitals.  Following  the  incident,  the  Indore  Municipal  Corporation,  Health  Department  and Public  Health  Engineering  Department  initiated  a  joint  response  including  hospitalization  of serious cases, door-to-door surveys, distribution of ORS packets and chlorine tablets, suspension of water supply through pipelines and borewells, provision of water tankers, and testing of water samples at NABL-accredited laboratories. The State also issued Standard Operating Procedures for  Urban  Local Bodies and launched the 'Swaccha Jal Abhiyan' from 10 January 2026. The

matter  is  sub  judice  before  the  Hon'ble  High  Court  of  Madhya  Pradesh  at  Indore,  which  has appointed Justice Sushil Kumar Gupta (Retd.) as a one-man Commission of Inquiry to examine the cause of contamination, public health impacts, adequacy of response, preventive measures, and responsibilities of concerned officials.

Drinking  water  contamination  in  urban  areas  is  generally  attributable  to  vulnerabilities  in distribution  systems  and  their  interface  with  sewerage  and  sanitation  infrastructure.  Although urban drinking water is required to conform to BIS IS 10500 standards, deterioration in quality may occur due to infrastructure-related, operational, environmental and maintenance factors across transmission, storage and distribution systems, including leakages, pipe bursts, defective joints, cross-connections  with  sewerage  and  drainage  systems,  ageing  infrastructure  and  corrosion, intermittent  supply  and  negative  pressure,  stagnation  and  prolonged  retention  of  water,  and inadequate  maintenance  of  storage  or  sewerage  systems.  To  address  such  risks,  MoHUA  has issued advisories to strengthen water quality monitoring, including community participation under AMRUT 2.0, and has published the 'Manual on Water Supply and Treatment Systems (Drink from  Tap)'  in  March  2024.  In  January  2026,  States  were  further  advised  to  undertake comprehensive assessments of vulnerable areas and ageing infrastructure, identify sewer-water line  crossings,  and  conduct  digital  mapping  of  water  and  sewer  networks  using  geospatial databases created under AMRUT/AMRUT 2.0.
