According to me water in Chennai is not available and affordable by all because:

(a) There are many areas like Anna Nagar where mainly the government officials reside who have tap water for a major part of the day. Not only this when there is scarcity of water at that time also a tank of water is being arranged for them.

(b) In Mylapore area people only get municipal water once in two days.

(c) If we look Madipakam that people gets water once in four days.

(d) Water is basic and very necessary need of humans but still it is not affordable to all. People who belongs to middle class or rich class can get it by buying water tankers or bottled water but poor have the least to water.
