Syllabus: Water for the World by Jim Smith

This is part of our Campus Spotlight on the Global Water Initiative at the University of Virginia.

 

Course Description

Potable water is essential for human life. Throughout most of the industrialized world, advanced water treatment systems incorporate fundamental physical, chemical, and biological principles into engineering designs to produce high-quality water at relatively low cost to consumers. By contrast, the World Health Organization (WHO) estimates that about one sixth of the world’s population (about one billion people) have no adequate water supply and less than one percent of the population in developing countries is served by sewage treatment facilities. Life-threatening water-borne diseases, particularly among children, are common in economically disadvantaged communities throughout the world.

In this course, we will examine complex issues associated with providing potable water to the world’s population. Topics will include the use of surface and ground water as potable water supplies, the fundamentals of water chemistry, the science and engineering principles used in the design of modern water and wastewater treatment and distribution systems, and the problems associated with providing potable water in economically disadvantaged communities, refugee camps, and developing and underdeveloped countries, including shortages of resources, lack of government support, inadequate institutional structures, and lack of local interest/acceptance. Case studies will be used as appropriate to demonstrate these issues.

Course Objectives

1. To develop a global perspective on water supply and treatment

2. To apply basic physical, chemical, and biological principles to design and understand water and wastewater treatment technologies

3. To highlight the differences between water supply, treatment, and management systems in the industrialized world and the developing and underdeveloped world

4. To leave with a “big-picture” understanding of current issues associated with provision of potable water to the world’s population
