Lectures on the following topics: Water as a resource, protection of water resources, the influence of various types of pollution on the quality of the drinking water and methods for treating drinking water. The classification of environmental quality in freshwater and chemical and biological quality requirements for water to be used with emphasis on drinking water regulations will also be covered. In addition, evaluation of different water supply sources will be considered. Regulation and mangements regarding water supplies/water management including the water directive. Group work: 3-4 students cooperate on a relevant topic that is presented in plenary for all the students taking the course. Excursion: 5-6 hour excursion.

The student is to understand the significance of water as a resource and be able to classify, protect and use different types of water for different purposes. Have knowledge of various sources that can be used for drinking water supply, the need for action in the drainage basin and water treatment according to the drinking water regulations. Have knowledge on reference condition in different water sources and the characteristics of different water types. Water quality and water pollution should be treated in a holistic perspective with the whole catchment as a unit according to the Water Framework Directive (WFD). Water is an important resource that must be managed correctly, all the time taking future generations into consideration.

The lectures are used for covering central topics in the course. Guest lecturers are used for some lectures to give examples of how the knowledge gained in the course may be used and so make the subject more concrete. Central topics are discussed during the course. Group work is used for giving students a more active relationship with the material. The students select topics from a list that is set up. The completed result is presented in plenary. An excursion to a drinking water plant and a sewage treatment plant in the Oslo/Akershus region are arranged to see how these plants really work.

Discussions are arranged under supervision of the teacher. The course intends to establish a good dialogue between the students and the teacher.
