Municipal Corporation Of Greater Mumbai — water wastage in society

I have come as a guest to this building in meera road, chamunda classic society, and stayed in building 1, i am very upset and disappointed to see the amount of water wasted which could be supplied to one small district. On enquiring i was told that the owner of the flat dispute of constant reminders, does not take any action, i guess, a heavy fine on individuals and society too should be levied for not understanding the value of what they are wasting, is a life for someone else. Morning 6-8, the water just flows and no one to pay heed to it. Please do take some action.
