Prerequisite Courses:  – Direction: Environmental Sciences Instructor:

The basic principles of the physical and chemical processes of water to be understood by the students. To emphasize the importance of the appropriate water management, starting from the water source till the treatment, so that it will reach to the final consumer at the desired quality in a reasonable cost without using up all the available water resources and without risking the future of the next generations.
