Dozens of residents in Greater Noida's Delta 1 sector have reported falling ill with symptoms like vomiting, diarrhea, and stomach ache over the past few days, allegedly due to sewage contamination in the drinking water supply. While residents blame damaged pipelines and aging infrastructure, the Greater Noida Industrial Development Authority (GNIDA) stated that initial tests found no evidence of sewage mixing. Authorities have repaired leaks and collected water samples for testing, assuring that the supply is now normal and safe.
