[Resolved]  MCD - Severage & Mosquito — Sewage blocked

C-31 Hauz Khas, New Delhi 110016; has a sewerage blockage. Sewer water is flowing out of the manhole for the last 1 week and the residents have not managed to get the same repaired. Because of this the number of Mosquitos in our house have increased.
Also, the whole area smells badly because of this sewerage backflow. This dirty water comes out this and accumulates in front of the adjoining & opposite houses.
Please advice on how to proceed and get rid of this menance.
