Course abstract

Study course includes wastewater management including domestic, industrial, storm water and agricultural wastewater. Will be theoretically obtained different wastewater treatment methods and students will practically approach the urgent wastewater treatment methods in Latvia. Sewage system technical designing will be studied during this study course.

Learning outcomes and their assessment

Study course will give
• knowledge of wastewater sources and amount and biochemical treatment principles of different wastewater treatment plants.
• Students will have a skills to adapt a wastewater treatment method and a discharge system suitable for current object. Students will be able to prepare a documentation of technical designs.

• Student will be competent to defend their solution in standard and specific cases, offering the most environmentally friendly, sustainable and economically viable option.

Requirements for awarding credit points

Independently completed practical assignments and a successfully passed exam on the lecture topic.

Description of the organization and tasks of students’ independent work

Students attends the theoretical course in the form of lectures covering all topics listed in the course syllabus. Lecture topics are distributed across sessions throughout the semester in accordance with the course plan. In preparation for the exam, students independently engage in in-depth study of the covered topics, using the recommendations of the lecturer and relevant literature sources. The exam consists of 30 multiple-choice questions, each with three possible answer options. Only one correct answer is allowed per question.
During the course, students independently develop a design project for internal and external household sewage systems, consulting with the lecturer. Input data, including topographical plans, soil composition, population figures, and other relevant information, are provided by the lecturer. The project is developed in accordance with the technical project quality requirements accepted in Latvia, at an appropriate level of detail, including design in both plan and vertical views. The explanatory report must include a description of the technical information, calculations, and address the issue of wastewater treatme.

Criteria for Evaluating Learning Outcomes

The exam for the theoretical part is organized in writing within the e-learning environment and consists of 20 questions. To successfully pass the exam, at least 50% (10 questions) must be answered correctly.
The practical assignment is assessed separately on a 10-point scale, and the evaluation includes both the developed solution and its defense.
The final grade for the course is calculated as the average of the theoretical exam grade and the practical assignment grade.
