The Traditional Means of Treatment:
Centralized Plants and Expensive Infrastructure
The traditional water treatment approach has been to build multi-million dollar
centralized treatment plants and install costly underground piping systems to
deliver it to users.
That approach has worked well for hundreds of years in densely populated areas, where sufficient capital is available for such projects.
However many of the billion people who lack access to sufficient safe drinking water to survive live in sparsely populated areas and/or they lack the funds necessary to build the plants and distribution systems needed for central processing.
