Bangalore Water Supply & Sewerage Board [Bwssb] — dirty water being supplied

Citizen of mahalakshmi layout, bangalore. I would like to complain that we are being supplied dirty water from past 4 weeks. I tried calling the customer service numbers but my calls were never answered. Fix the issues quickly. We do not want to fall sick. If we get any disease after using this dirty water we will take legal actions against your board.
