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
Page 1 of 7up 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
Page 2 of 7matter 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.
