Lucknow Nagar Nigam — Sever tank lid open

Address:

C-2153/2, Indira nagar lucknow,pin-226016

Sir,
The sever lid( cap) near my house is not fixed. We tried to fix it with cement but it broke after some days.
There is a possibility of theft if the sever cap remains unfixed, which will be dangerous for any resident.
Kindly send any specialist to fix the sever cap.
