Sewer water in tap?!

Hi everyone, A South Delhi resident here. We have been getting foul smelling yellow water in our taps. Thought it was just us till the RWA said there was an issue from Delhi Jal Board. Def Col also has horrible water. It's been going on for a week now. DJB says there's some mix up in pipes. I was wondering if anyone else in Delhi is facing this issue? Sewer water in tap can cause water borne diseases. So please be careful. Boil drinking water just to be sure. I haven't bathed in a while. I can't believe this is our city. First time in 3 decades. So disappointed.
