Several residents of Greater Noida's Delta 1 sector fell ill after allegedly consuming contaminated drinking water, triggering health concerns and complaints of sewage mixing with the potable water supply, officials and residents told news agency PTI.
Residents reported symptoms, including vomiting, fever, stomach ache, and diarrhoea after consuming tap water in parts of the sector on Tuesday and Wednesday.
However, officials of the Greater Noida Industrial Development Authority (GNIDA) denied any sewage contamination of the water supply, stating that tests conducted so far had found the water to be clean, PTI reported.
Rishipal Bhati, a resident and former president of the local residents' welfare association (RWA), told PTI on Thursday that sewage overflow and pipeline leakages, especially in C Block, led to the problem.
"Around six to seven families fell ill with symptoms such as vomiting, fever and loose motions after consuming contaminated water," he said, adding that similar complaints had earlier been reported from other blocks as well.
The incident comes amid heightened concern over water safety following recent cases in Indore, Madhya Pradesh, where multiple deaths were linked to consumption of contaminated water, and in Gandhinagar, Gujarat, where several people reportedly fell ill due to polluted water supply. Authorities across states have since stepped up monitoring and testing of drinking water sources.
Residents of Delta 1 alleged that sewage water from blocked sewer lines was mixing with broken pipelines and reaching household taps. One resident complained of severe stomachache after consuming tap water, while others said water leakage has been a recurring issue in the sector.
Harendra Bhati, a resident of the neighbouring Beta 1 sector, claimed that sewage overflow is a common problem in several parts of Greater Noida.
"I have raised the issue multiple times, but no permanent solution has been implemented," he said.
GNIDA officials said the authority took immediate note of the complaints on Wednesday, with a water department team visiting the affected homes and collecting water samples.
"The samples were found to be clean. There was a supply connection issue in one house and a leak at another, which were fixed immediately," a senior GNIDA official said.
Officials said Greater Noida Authority CEO N G Ravi Kumar has directed random water testing across the city in view of similar incidents reported elsewhere.
Additional CEO Sunil Kumar Singh said the water department has been instructed to conduct random testing in all areas supplied by the authority.
"Fresh samples were collected again on Wednesday evening after the water supply resumed, which will be sent for testing," he said.
Singh added that builders and apartment owners' associations have been directed to regularly clean water reservoirs, get samples tested and submit reports to the authority.
He said a letter is also being issued to residents urging them to immediately report any instance of contaminated water supply.
Meanwhile, the health department organised a free medical camp in Delta 1 on Wednesday, during which 23 people were examined and seven patients suffering from vomiting and diarrhoea were treated, Gautam Buddh Nagar Chief Medical Officer Narendra Kumar said.
