Safe Drinking Water

This video looks at the availability of clean water around the world and solutions to the problem of water borne diseases. A water and waste engineer talks about her work in water treatment technology. She explains the steps involved in treating water for microbial contamination – filtration and disinfection. Arsenic is removed from the water using iron nails which rust and act as an absorption media. The engineers explain how they are helping poor communities by developing simple, low-cost solutions which use local materials that are readily available in the countries in which they are working.

The video, from the Institution of Engineering and Technology (IET) is part of the Pure Water collection of resources.
