Delhi Jal Board — sewer overflow, karol bagh, new delhi

Address:

4/21, WEA SARASWATI MARG, KAROL BAGH, New Delhi, Delhi, 110005

Our Street's sewer is completely block again since month. its difficult to even walk on the street due to overflow of sewer, And its becoming the primary source of mosquitoes as well.
Earlier around 1 months back, i raised the complaint for the same. After several followups they came and did the the very temporary work (Just spent 10-15 mins) and assured us that all water would be cleared automatically as they have cleared the Mainhole. But that statement was just to close the ongoing complaint without putting any effort. Then Problem of sever blockage again started just after few days, and getting worst day by day.

Why they have not cleared the sub and main holes thoroughly so that atleast it would work for next 6 months?

Requesting to all higher authorities to look into this matter and solve this sewer overflow issue ASAP.
