Hundreds of residents across multiple housing societies in Ahmedabad's Ghatlodia area were taken ill, complaining of diarrhoea and vomiting, over the last four days after consuming contaminated water, officials and residents said.
A leaking pipeline led to mixing of sewage with the Narmada water supply to the area, prompting residents to flag the problem on Friday.
Repair work began only past midnight, and when supply resumed Sunday morning the water still carried a foul smell, forcing a second round of repairs.
Around 50 cases were reported at the OPD level, most of them treated and discharged after day care, according to Ahmedabad municipal commissioner Banchanidhi Pani.
Over 500 residents of Akanksha Apartments, 200 residents of Navratna Avenue, 100 residents of Vande Mataram Flats, and 50 residents of Vinayak Bungalows fell ill, residents claimed.
