Delhi Jal Board — drinking water supply issue

Address:

C-47A, Front Side, 3rd Floor, Rama Park, Uttam Nagar. Near Verma Chowk, Shisha Godam Road., New Delhi, Delhi, 110059

My address is c-47a, front side, 3rd floor, rama park, uttam nagar nd-110059 (Near dwarka more metro). From last couple of days, we are struggling with drinking water supply. Sewar water is coming when ever we turn on our motor. It smells like hell and my all near by residence is having the same problem. Multiple complaints are logged, however there is no action taken so far. Would request the concerned person/authority to have a look at this serious matter.
