Municipal Corporation Of Delhi — Sewerage line Blockage block 8

I am a resident of 8/338, Trilokpuri New Delhi.The sewerage line in our area specially in my location get blokage many times. I have the ground floor and my kitchen line always blocked and the dirty water spells over bathroom .Despite lodging complaint several times to authorities, nothing has been done so far. There is dirt and filth all around. Faeces is overflowing. Our Kitchen line and toilet lines are also blocked. We request an immediate action to restore cleanliness I shall be grateful, if my complaint will be looked expeditiously and I may be relieved of such a dirty condition. It is always noticed that the sewere line which moves from my residence have complained but never been clerared by the Jal Board. Even the lids of the severe line are open in the area, which may cause any uncertainity in future.Let's see how much the word of your i.e. CLEAN AND GREEN DELHI.is True?
Thanks,
Deepak kumar
