Part II
Drinking Water Treatment
Technology and Pricing
In Part II, we attempt to answer the following questions:
As reliance on chlorine is inadequate, what are the other treatment technologies
and their respective average costs, for any given scale of water production?
Can we classify these treatment technologies on the basis of what contaminants
they can remove?
Does the removal of more contaminants always lead to higher average costs, for a
given scale of water production?
Is there a treatment technology that is the
“
state-of-the-art,
”
in that it can remove
almost all contaminants at an affordable cost?
What are the theoretical mechanisms of pricing water?
What are the main actual pricing mechanisms used in the developed countries?
Can fairness, equity, and other moral judgments be embedded in the way water is
priced, for different populations, such as the rich and the poor?
