The phrase "free access to water" refers to the idea that everyone should have unrestricted and unfettered access to clean, safe drinking water. This means that water resources should be managed in a way that ensures that all people can easily obtain and use water for their basic needs without facing any barriers or obstacles. The concept of free access to water is closely tied to the human right to water, which recognizes that everyone has the right to safe, clean drinking water as a fundamental aspect of human dignity and well-being.
