Bangalore Water Supply & Sewerage Board [Bwssb] — Sewage issue

Drainage oozing our from all the man holes in P&t layout and also affecting in our houses. The drain water is coming in through toilets and sinks which is causing a very bad smell. This needs to be fixed asap as we will fall sick and there are many old people and kids at home. Multiple times the complaint was raised, no one is bothered.
