Sewage and Waste Water Management

At the end of this course, students should be able to: 1. explain the terms sewage, waste water, waste water management; 2. calculate waste water flow rates and run off; 3. monitor of sewerage system; 4. describe primary, secondary and tertiary treatment; 5. identify basic waste water treatment methods; 6. design a community sewage and waste water treatment plant; 7. discuss sanitary aspect of sewage and waste water treatment at the municipal level; and 8. explore Business opportunities in sewage management.
