Bangalore Water Supply & Sewerage Board [Bwssb] — No supply of water

There is always a irregular supply of water in our area that is jayanagar 8 block 1st B main, how come the issue is only in our road whereas in other roads there is regular supply of water.
Every 10 days we are forced to get tankers
I request authority to take the matter very seriously as we the common men are affected very badly.
Today we had called the BWSSB bsk 2nd stage stage and inform them they said they will be leaving water by 8:00 p.m. tonight but till now there is no sign of water, We are having aged parents and patients at home
