A couple of decades ago, people turn to the tap for drinking water. Now, most people, both young and old, drink water from bottles. In fact, the demand for bottled water is so great that it has become a multimillion-peso business in the country today.
Why is there a substantial growth in the demand for bottled water? The main reason is the increasing health consciousness of the people.
