The civic body is baffled over source of the contaminated water that certain parts of the city have been receiving for the past five days.
Residents in Andheri, Jogeshwari and Masjid have been complaining of getting yellow-tinted water for the past few days.
Raising the issue in the standing committee, Shiv Sena corporator Rajul Patel said various areas in her ward in Jogeshwari were getting water with a yellow tint and residents were getting worried.
Congress corporator Waqarunnisa Ansari said residents in Masjid, Musafirkhana, were also getting contaminated water.
Jyotsna Dighe from the Congress alleged that Andheri residents were getting similar coloured water for the past few days.
“The water has not caused any health problems, but residents are scared,” Dighe said.
Replying to this, additional municipal commissioner Aseem Gupta agreed that many areas in the city were receiving yellow-tinted water and said investigations had been initiated on a war footing by the hydraulic engineer department.
“But, we have not been able to find the source of contamination,” Gupta said.
Water samples taken from the reservoirs in the western suburbs are tested and found to be as per Indian standard specifications.
Now, samples of extensively contaminated water have been sent to ascertain the cause of contamination, Gupta added.
Civic officials have appealed to Mumbaiites not to panic and consume water only after thoroughly boiling and filtering it.
Meanwhile, Patel has said that residents of Jogeshwari were also not receiving enough water supply. Despite hydraulic department officials promising adequate supply, it has reduced further.
She threatened to go on a fast at the chief hydraulic engineer’s office if the water supply issue was not resolved soon.
Standing committee chairman Rahul Shevale directed the civic administration to regularise water supply to the affected areas at the earliest.
