Bangalore Water Supply & Sewerage Board [Bwssb] — sewage overflow and blockage

Address: Bangalore, Karnataka, 560060

Dear sir, the manhole in 1st a main road, often overflows due to blockages and rainfall.
This is there since decades but umpteen no. Of times complaining, nothing has been done.
There is a bar called thirumala bar who leaves all solid waste materials into drain and also he leaves all those into roadside gutter.
Few days back, because of all these reasons, my hospital was flooded inside full of sewage. We have lots of rodents, flies and mosquitoes in the vicinity, which is health hazard. Even now road is overrunning with sewage water and lots of smell and odour.
I brought notice this to mr. Chennappa, the incharge assistant engineer but he has not bothered to attend.
I request you to
1, clean the blockage
2, change the drains to bigger size
3, disconnect the sewage connection to the bar.
4, punish the bar management for leading the sewage waste into the water gutter by the roadside.
