CE74.41 : Water Supply and Sanitation  3(3-0)
 
Course objectives:
The objective of this course is to provide students with engineering principles and tools for designing and operating water supply and sanitation systems. It focuses on how to deliver effective modern water supply, sanitation and other public health interventions in urban and rural areas. Particular emphasis is placed on developing the students’ understanding of technical interventions in water supply and sanitation.
 
Learning Outcomes:
The students on completion of this course would be able to:
  • Comprehend the wide range of health and social issues related to water, sanitation and hygiene;
  • Identify and apply a range of suitable technologies for the treatment and delivery of municipal water supply;
  • Comprehend the elements of systems for sanitary collection, storage, treatment and disposal of human waste, both on-site and off-site, their function, design and modes of operation, and suitability in both urban and rural settings; and
  • Design simple water supply, and wastewater, systems in urban and rural areas.

Time Distribution and Study Load:
Time Distribution and Study Load:
Classroom lectures                           40h
Tutorials                                               10h
Field visits                                            05h
Self-study (incl. assignments)        135h
 
Teaching and Learning Methods:
Teaching and learning methods include classroom lectures and discussions, tutorials, individual and group assignments, and computer modeling and field visits. Field visits are designed to expose students with water treatment and distribution system including raw water intake, pumping system and monitoring system (SCADA) and with wastewater treatment plant. Published journal papers are given to the students for self-study to enhance their understanding of the subject matter.
 
Evaluation Scheme:
The final grade is computed according to the following weight distribution: Mid-semester Exam (30%), Final Exam (50%) and Assignments including field visit report (20%). Open-book examination is given in both mid-semester and final exams.

 An “A” will be awarded if a student is able to demonstrate exemplary knowledge and understanding of the principles, technologies, and design of water supply and sanitation systems. Furthermore, it is also expected that students in this category will demonstrate very good awareness of water and hygiene issues, especially in Asia, and be able to participate in discussions on related matters. A “B” will be awarded if a student is able to show adequate understanding over the theoretical subject matter. However, practical application in designing the water supply and wastewater systems is found wanting. A “C” will be given if a student is able to show satisfactory command over the subject matter. A “D” will be given if a student is able to show very limited knowledge, and application, of the subject matter, and does not appear motivated to learn new things.
