Bangalore Water Supply & Sewerage Board [Bwssb] — leakage of sewage water

Address: 560076

Hi bwssb authorities,
I am a resident of arekere bts layout.
Opposite to prv residency, there is a severe leakage of drain water and it is unattended for almost 1 year even after more than 20 compliants.
The gps location is: https://goo.gl/maps/JLmN88QG75UmbZJ18
It would be really great if bwssb authorities can address this as early as possible as there has been repeated dengue incidents in our locality.
