We are constructing a house in k r puram, since dec 2017, bwssb is charging rs.1850/- per month, even we are using 1000 ltrs of water.
When i enquired they said, we have converveted your connection as a non domestic, so we are charging borewell charges rs.1000/- and rest is water charges and seawage charges. It is too hight, it is like looting the people.
It is a individual house, not a appartment or office.
