On the one hand, people who live in residential areas believe that they can consume fresh water as much as they want, because they consider it a clear residential right. Governments should provide them with infinite fresh water. There are some rules that must be considered in which fresh water is not only for citizen consumption, but also for improving hygiene. If all water resources allocated to residential areas, hospitals and drug producer companies, which are two important factors in public health, do not have access to fresh water to do their duties to increase public hygiene.
