Noida water contamination: Residents blame Indore-like sewage mixing as vomiting, diarrhoea cases rise

Greater Noida Water Contamination Case: After the Indore water contamination incident that claimed over 10 lives and left around 200 people ill, similar cases were reported in Bengaluru and Gandhinagar. Now, fresh concerns have emerged from Greater Noida, where dozens of residents have fallen sick after sewage reportedly mixed with the drinking water supply.

Residents of Sector Delta 1 in Greater Noida have complained of vomiting, diarrhoea and fever, triggering fears of an Indore-like outbreak.

Sewage Mixing With Drinking Water Triggers Health Concerns in Greater Noida

According to residents, sewage entered the drinking water supply after a damaged pipeline allowed contamination in parts of Sector Delta 1. Several families, including children, have reported stomach infections over the past few days.


Officials from the Greater Noida Industrial Development Authority (GNIDA) and the health department inspected the area on Wednesday. The leak was repaired, and medicines, ORS, glucose and anti-inflammatory antacids were distributed among affected residents. Water samples have also been collected for laboratory testing.

Residents Fear Repeat of Indore Water Contamination Case

The incident has raised serious concerns among locals, who fear a repeat of the Indore tragedy that resulted in multiple deaths and mass hospitalisations.

Residents have demanded better monitoring of water supply lines, pointing to repeated leakages in the sector’s three-decade-old pipelines and the poor quality of supply water.

Leak Plugged, Water Samples Sent for Testing: GNIDA

GNIDA assistant manager (water department) Manoj Choudhary told TOI that a dilapidated section of the water pipeline in Block C was found leaking and was repaired immediately by Wednesday afternoon.

He said inspections were carried out across the sector, during which two additional leaking pipelines were identified and replaced. “We checked the quality of the water supply after the repairs in the evening and found it to be normal,” Choudhary said.

Medical Camp Set Up After Residents Report Illness

Dr Narayan Kishore, CMS at CHC Kasna, told TOI that the health department acted promptly after receiving information from the residents’ welfare association (RWA).

“Around 30 people visited the doctors. Five to six were given medicines, while the others were advised ORS. The situation is under control, and if required, we will organise another medical camp,” he said.

However, residents claimed that cases of diarrhoea had started emerging as early as Monday.

Children Among Those Affected, Say Residents

Pramod Bhati, president of the Sector Delta 1 RWA, told TOI that at least 12 people have fallen ill so far, including children aged between 12 and 15 years.

“Most of the affected residents are from Block C, where the pipeline ruptured a couple of days ago. They complained of vomiting, fever and loose motions,” he said.

Bhati added that this was the third instance of pipeline damage reported within a week in a sector that houses nearly 20,000 people across six blocks, from A to F.

Residents Blame Blocked Sewer Lines and Old Pipelines

Residents alleged that blocked sewer lines were diverted into a drain, allowing sewage to seep into a leaking water pipeline that runs through the same channel.

Rukmani Singh (42), a resident of Block C, told TOI that she suspected water contamination when she first fell ill. “I felt uneasy and soon developed loose motions and extreme weakness,” she said. Several of her neighbours, including a 12-year-old girl, reported similar symptoms.

Civic Neglect Despite Greater Noida’s Growth Claims

Locals have criticised civic authorities, saying basic amenities continue to lag despite Greater Noida being projected as an industrial and investment hub.

“Instead of repairing the blocked sewer line, it was diverted into a drain. The uncovered manhole allowed dirty water to seep into an old, leaking pipeline,” said Deepak Kumar Bhati, convenor of the sector’s RWA. “We pay our bills, yet we are forced to use contaminated water.”

GNIDA Assures Priority Repairs and Pipeline Replacement

Choudhary urged residents to immediately report any water or sewer leakages, assuring that such complaints would be addressed on priority.

He said GNIDA teams are working continuously to maintain water supply lines and that proposals are being prepared to replace pipelines in older sectors facing persistent problems.

General Safety Measures Residents Should Follow

Health experts advise residents to take basic precautions until water quality reports are confirmed:

• Boil drinking water for at least 10 minutes before use, especially for children, the elderly and those with weak immunity.
• Avoid using tap water for drinking, brushing teeth or making ice unless it is boiled or filtered properly.
• Use packaged or RO water temporarily, if available.
• Wash hands frequently with clean water and soap, particularly before meals.
• Clean water storage tanks and containers regularly to prevent bacterial growth.
• Report any foul smell, colour or taste in water immediately to civic authorities.
• Seek medical help early if symptoms such as vomiting, diarrhoea or fever appear.
• Avoid street food and uncooked food items until the situation is fully under control.
