Bangalore Water Supply & Sewerage Board [Bwssb] — drainage pipe broken and leakage of drainage from manhole

I have lodged a complaint its no is bwssb[protected]. They came and cleaned the manhole but there is a damage in main drainage pipe that has to be fixed, due to these waste water is leaking in and around pipe, creating lots of problem. It frequently gets blocked and waste water leaks. People are facing lots of problem due to these. Its leaking into our water tank also. So request to look into these as earliest as possible.
