In choosing to buy a bottle of water or fill a glass bottle with water from the tap, we compare all stages of their life cycle. For water taken from the tap, it should be noted the construction of the container and the management of the aqueduct, the systems of abstraction, treatment and distribution. For bottled water, things are more extensive, there are the activities of collection, treatment quality control, bottling, all transport related by withdrawal of water to the distribution of the finished product, then we have to add energy and resources used to produce bottles, mostly of plastic, and remember that the plastic is obtained from non-renewable raw materials. The consumer buys the bottle and carries it yet, from the point of sale at home. At the end of life if the bottle is not recycled ends up in landfills. Using methods such as Life Cycle Assessment to calculate kg hansen the environmental impact of the two systems to get water, you obtain the result that the tap water has a lower environmental impact of bottled water, is also controlled four times more frequently, and the content of salts and other substances is adequate to our needs health. A study conducted on public water systems of some large Italian kg hansen cities, in most cases the water was of excellent quality. Research has highlighted the economic advantage, ie a family kg hansen drinking water from the tap can save in a year about 500 euro.
