Indore Municipal Corporation [IMC] — Water quality

Iam residing in Goyal Vihar colony near khajrana Ganesh mandir. Today we when we open Narmada water tap to store for cooking and drinking purpose. To our shock we found that water was mixed with some oily substance floating on top. This is not acceptable and cannot use for human consumption. We need an immediate enquiry into this and the problems should be addressed on top priority with assurance of repetition.
