The bottled water you are consuming either at home or outside isn't necessarily drinkable as it may not be processed involving standard procedure. The packaged water one may be consuming could possibly just be tap water or ground water. Out of nearly 53 bottling plants supplying packaged water in city, only 18 have ISI certificates.
With the summers setting in, leading to water shortage, consumption of packaged drinking water has shot-up in the city. According to an estimate, the city consumes anywhere between 30,000 to 40,000 bottles (20 liter capacity) of water per day.
