Water is not a commercial product like any other but, rather, a heritage which must be protected, defended and treated as such (Dir 2000/60/EC). Characteristics and uses of water depend on different activities, agricultural, industrial and civil, and country income. Water is an element always present in citizens life but water is also used to make every product on Earth, and so all business, and all sector, depend on it in some way, so daily custom of citizens can influence the consumption of water, precious water for physiological intake and domestic use but also for aquatic and terrestrial ecosystems. Sustainable measures must be developed and existing initiative must be improved. It is useful develop a planning of prevention and safeguard measures between citizens, water management service, administration and health authorities because the time of natural recharge of water is so long.
