The consumption of water
We need water to drink and for many more activities that we humans carry out. But although there is plenty of water, only a small part of fresh water is available, and if it runs out or is spoiled by pollutants, this resource becomes scarce. That is why it is necessary to raise awareness and carry out sustainable water management, avoiding its contamination, overexploitation, and waste. It is about taking measures that guarantee its use but without endangering its availability for future generations.
They can be distinguished by types of water uses:
- Non-consumptive uses of water. They are those uses in which the water is used but not spent and can be reused for another purpose, such as:
- The use of water as a source of electrical energy in hydroelectric plants, moving waterwheels, etc.
- The use of water as a means of communication and transport of people and goods with boats that navigate rivers, lakes and seas.
- The use of water for sports and leisure, to bathe in swimming pools, rivers, seas, etc., to do scuba diving, surfing, swimming, water polo, canoeing, skiing, etc.
- Consumptive uses of water. They are those uses in which the water is spent and cannot be used again. For example, the water that is used in agriculture, livestock, industry, ... once it has been used, it cannot be given another use.
Some of the possible uses of water are as follows:
