Bangalore Water Supply & Sewerage Board [Bwssb] — sewage/sanitary waste flow in mantri lakeview layout without drainage

Address: 560109

Storm water, sewage and sanitary waste from talaghatpura flows into mantri lakeview (Opp coca cola warehouse). During any rains, the storm water brings all the sanitary waste into mantri lakeview without any drainage created or illegally connected to our layout.
Drianage system is not available in this area, but the sewage flow from talaghatpura is connected to our layout without any thinking on sewage and sanitary waste flow going thru' a residential layout!
