Bangalore Water Supply & Sewerage Board [Bwssb] — Un-Scientific Charges on New Water Connections

Address: Sir. M V. Layout 6th Block, near KLE Law College, Bangalore-560091

BWSSB, Bangalore takes a hefty charges for providing a 1/2 inch water supply to BDA approved residential houses. Once the connection is taken they put extra charges which is more than the water consumption charges. When enquired, the officials say OC is required to remove this extra charges.
What is the significance of OC for BWSSB?
If OC was that much required why did they approve the connection without asking for it?
Are they putting these extra charges for older connections also?

Being a board operating under state government, How can they have difference in charging to subscribers?

The official say its board decision to put such charges. We are not sure how to and whom to address such issues.

Please help..
