Bangalore Water Supply & Sewerage Board [Bwssb] — regarding sewerage board

Address: 560002

I am staying at ms lane, nagrathpet, bangalore -02, here from past three days the sewage water is flowing on the road which is making the pedestrian difficult to walk. And when we call to the number[protected] it's showing as busy.
So please i request you to make the arrangement as soon as possible and do the need full.
Regards
The pedestrian
