Bangalore Water Supply & Sewerage Board [Bwssb] — water mixed with drainage water being supplied to our homes

Address: 560064

I am a resident at sharada nagar yelahanka new town. The homes in our street that is first main road sharada nagar are getting water mixed with drainage water since 15 days. We hve reported it to local officers and no action is being taken. The water smells horrible and is not even fit to use for sanitary purpose. I i request concerned authority to take immediate action.
