An early investigation into a diarrhoea outbreak in Indore’s Bhagirathpura area has confirmed the presence of bacteria commonly found in sewer water in drinking water samples, officials said on Thursday. The contamination has been linked to the deaths of at least nine residents, while more than 2,400 people have reported symptoms such as vomiting and diarrhoea.
Health officials stated that the contamination was likely caused by a leak in an ageing sewage pipeline that allowed wastewater to mix with the drinking water supply. Laboratory tests have confirmed abnormal bacterial presence, though the exact pathogen will be identified once culture and stool test reports are received.
According to the local administration, residents first noticed an unusual smell in the water supply around December 25. The situation worsened in the following days, leading to a sharp rise in illnesses. At least 162 people are currently hospitalised, while many others are receiving treatment at home or outpatient facilities.
Dr Arvind Ghanghoria, dean of Mahatma Gandhi Medical College in Indore, said the initial findings point to contamination involving human waste. “The culture report will help us identify the specific bacteria. Stool test results of affected patients are also awaited,” he said.
Officials clarified that while 14 deaths were initially reported in the area, the probe committee has confirmed that nine were directly caused by diarrhoea linked to contaminated water. Other deaths were attributed to pre-existing health conditions or unrelated causes.
Madhya Pradesh Chief Minister Mohan Yadav visited affected residents undergoing treatment and assured them of full medical support. Additional Chief Secretary Sanjay Dubey, who is heading the probe, inspected the suspected leakage site and directed officials to conduct random water sampling across other parts of the city to prevent further incidents.
The National Human Rights Commission (NHRC) has taken suo motu cognisance of the matter and issued a notice to the Madhya Pradesh government, seeking a detailed report within two weeks. The commission noted that the incident raises serious concerns about the right to safe drinking water.
Meanwhile, the state government has announced financial assistance of ₹2 lakh for the families of confirmed victims. Authorities have also initiated disciplinary reviews to examine lapses in maintenance and monitoring of the city’s 30-year-old water pipelines.
Officials said emergency repairs are underway, and residents have been advised to avoid using tap water for drinking until further notice.
