1. One of the most ancient water wells with a depth of 88 m was found in the Cairo area. According to scientists, it was developed 3 thousand years ago.
  2. One of the ultra-deep (at that time) water wells (450 m) was developed in China. It was drilled by the impact method at a speed of 1 m per day.
  3. According to statistics, every American uses about 80-100 liters of water per day, most of which goes to sewage. Some foreign countries have reduced the standard volume of water consumption to 6 liters. A person consumes up to 60 tons of water in 1 year only in the process of nutrition.
  4. Water is a good solvent of all kinds of compounds, so there is no “pure” water in nature that does not contain various additives (salts, minerals and other chemical elements).
  5. The body of an adult consists of 65% water, in overweight people this indicator is reduced to 50-55%. In newborns, the bulk of the body weight — about 80% — is water. If the human body loses more than 10% of water, then it can die.
  6. A person feels very thirsty if the volume of water in the body decreases by at least 1% of the total volume. With a slight dehydration of the body (about 2% of weight), a person loses strength, gets very tired. The cause of dehydration can be not only physical activity, but also overeating. If you constantly consume structured water in increased doses (from 65% to 85%), then you can prolong life for about 15-20 years, in addition, it stimulates the regeneration of tissues and all functional processes.

  9. 70% of the total volume of water used by mankind is consumed in agriculture, in industrial production – 22%.
  10. The volume of fresh water on Earth is 2.5 – 3% of the total volume of water available on the planet, while underground the amount of fresh water is many times greater than on the surface. The world ocean occupies approximately 71% of the planet’s surface (at an average depth of 4 km) and contains 97.6% of the world’s known reserves of free water.
