Hyderabad Metropolitan Water Supply & Sewerage Board [Hmwssb] — receiving water by paying unaccountable amount

Address:

Hyderabad, Andhra Pradesh, 500004

I live in shreemukh's kontham towers, brahmanwadi, begumpet. For more than 2 years now our association has been paying rs. 20, 000 (Unaccountable amount) to someone in your hmwssb department to receive additional water apart from the regular water that we receive and pay the bill amount accordingly.
I have even sent several emails to the management including the md but to my surprise, there has been no resolution which gives me a feeling that this is how the residents can get additional water from hmwssb department and those who cannot pay will not get any water. It is very sad and i feel that this kind of activity has to be checked and stopped going forward.
