Water is a limited resource but we human don't stop increasing. Acording to the UN program, one person should use 50L water everyday necesarily. But almost none could reach this.
There are problems not only of water quantity but of water quality. In fact, flowing water quality (but your french version is la quantite, absurd!) can be damaged by pollution. Water pollution is mainly caused by the urbanisation but human activities are also to be blamed.
70% of water is used in agricultural sector, so if the water was polluted, the plants would also be polluted, and then the people living on them would be contaminated.
In the dry country, people have to walk long way to find water. They pay the water higher cost with uncertain quality though.
It's also one reason for conflicts, along the Nile which runs through 10 countries. In the upstream, you can find the dams that results in less abundant flood and weak waterflow.
The new technologies, such as the purification stations, have been ready to diminish the pollution.
In the hot and dry countries, the desalinisation stations have also been built to convert seawater into clear water. The only inconvenience is: it's expensive and energy-consuming!
Some countries also build up wells that draw underground water, but this will result in waste of underground water and loss of vegetation in the long run.
Water is essential not only for human but for animals and plants.
