There are billions of people worldwide that do not have access to clean water and sanitation. This results in millions of deaths each year including over 1.5 million children. There are many place without even a basic toilet. In contrast, developed countries are using using science and engineering to develop sophisticated technology to remove minute levels of contaminants, capture nutrients from wastewater for use as fertilizer and capture the energy embedded in the waste to reduce energy dependency and carbon footprints.
Jeanette Brown, immediate past president of the Water Environment Federation, outlines general issues related to water and sanitation and the needs of the developing world and what can be done to improve public health; in addition, she describes the sophisticated technologies which allows for the direct recycling of wastewater.
