Bangalore Water Supply & Sewerage Board [Bwssb] — The bill is too high

Monthly the water bill comes around 3800rs to 5100rs every month.
Its been almost a year that it has happened.
Till now we all tenants were out of station due to covid situation. Just paid the bills because we afraid of dissconnection of water.

The problem is, there is no leakage at all. No problem with under water tank as well as upper tank. And hardly 1 or 2 persons used water.

However, the bill is too high and its very much unfair to pay off the amount.
Please we shall kindly request you to send one officer to look after this issue and resolve.
