Universities generally charge students for water, that is, the cost of hot water, which depends on the regulations of the school and the amount of students.

Generally speaking, the cost of hot water in university dormitories is charged according to each semester. For example, the cost of hot water for one semester is 50 yuan, and students need to pay the corresponding fee every time they use hot water. This can better save the resources of the school.

In addition, universities will charge students according to the amount of hot water they use. For example, a certain amount of water per semester is free, and if it exceeds this range, you will have to pay extra.

In this way, students will pay more attention to saving water, thus saving school resources.

In addition, the university will also carry out some publicity activities aimed at saving water, such as organizing community activities regularly to publicize saving hot water, so that students can better understand the importance of saving water, thus saving the resources of the school.

In short, the hot water in the university dormitory is not free. The school will charge students according to the amount of hot water they use, and at the same time, it will also carry out some publicity activities to make students pay more attention to saving water, thus saving school resources.
