Bruhat Bengaluru Mahanagara Palike [BBMP] — Manhole drainage smelling

Address:

Ramanuja Enclave apartment,kodipalya

We experience a lot of drainage fumes/smell from the main road man hole present very near to the apartment wall.
It is becoming harder to live due the bad smell.
Especially during night time till early morning, it smells very harsh.
Please take some necessary action.
Let me know if can take a close look at the issue and resolve at the earliest.
