Obtaining Drinking Water
Water covers about 71% of Earth's surface, but only about 3% of that water is fit for drinking. And of this 3%, only about 1% is
easily accessible. Many countries, including some economically developed countries, face a shortage of water because of
depleted resources and climatic conditions. In this task, you'll learn about several processes that can be used to purify water
for drinking.
Part A
Suppose that you manage the public works department for your community. You've been asked to develop a practical
process for providing drinking water for all the residents. List the criteria and limitations that you must keep in mind while
designing the process or facility.
