Municipal Corporation Of East Delhi — Regular frequent cleaning of sewage manhole

Very frequently our manhole in the service lane in the backside of our house No.D-300, Anand Vihar, Delhi-110092 gets blocked and our house gets sewage water inside our bathrooms and kitchen and we have always to rush with complaint. Nobody on their own cleans this which results in blockage very frequently.
I am an NRI owning Ground Floor of above house No.D-300, Anand Vihar, Delhi-110092 which gets affected and we are forced to get it cleaned very frequently.
I request somebody to visit our GF house and see the conditions for themselves and ensure timely cleaning of outside manhole and never allow this to get blocked.
