The right to clean water and sanitation is far less definable and depends on economic development, technology and infrastructure. Above all, if people have a right to water and sanitation, other people must provide it--in practice, governments using public money. Such privileges are called “positive rights,” as opposed to the inaptly-named “negative rights” to things that cannot be taken away from you. So this is really a call for state intervention, at the expense of other priorities and freedoms--and water is no more a practically enforceable human right than other essential commodities such as food, clothing or shelter.
