Lucknow Nagar Nigam — sewer blockage and overflow

Address:

INDIRA NAGAR, C -1327, Lucknow, Uttar Pradesh, 226016

Sewer is blocked and is overflowing since the past two months. It is just in front of my house and smelling very bad for one week.
I have already complained to the sweeper of the local area but the problem has not been resolved yet.
Kindly take the necessary action as soon as possible since it is very difficult to live in such unhygienic conditions.
