Bangalore Water Supply & Sewerage Board [Bwssb] — no/irregular water supply at health layout

Address: 560091

Area affected-HEALTH LAYOUT, Srigandakavalu, Nagarbhavi, Bangalore-91
Issue-Very irregular/nil water supply (Area authority name-Shankarappa)
We have been facing this problem since more than 3 months. The above stated person DOES NOT turn on water supply for the area at regular day intervals and DOES NOT follow a systematic timing. He turns on water supply at either 5pm, 10pm or 6am or in the middle of the night, and the days ARE NOT regular-either once in 3 or 4 days and the supply is very less/thin. A small size sump takes 6+ hours to fillup. We are forced to buy tanker water about 4-5 times a month due to this irregularity as we are not sure when/how much water will be available to us in this area.
Earlier we were getting water once in 2 days and at specific timings in the evening. Please address this issue at the earliest as this is affecting our drinking water needs.
