Bangalore Water Supply & Sewerage Board [Bwssb] — Incorrect and wrong Bill

Address: 222-7 Reliable Lakedew Residency Haralur Road Bangalore 560102

In past 2-3 months, I can see water bill is coming almost 10 times when we started.

The meter reading is wrong, as I have only 5000 Ltr. capacity of Sump and only Monday water comes for 2 - 3 hours, how can a family of 4 can spend 100, 000 Liters of water in a month when the total sump capacity is around 6000 Liters including over head tank (Consumer no: VS00147)
