Water Treatment

Water treatment is the act of cleaning water to make it safe for drinking. Clean, fresh drinking water is essential for survival and healthy living, yet access to the equipment and technology to do so is not something to take for granted. A 2007 study found that 3900 children died a day due to unsafe drinking supplies. More recent studies fear that due to water scarcity the situation will only get worse, and engineering companies are working hard to develop technological aids to combat the situation.
Adequate safe drinking water is something that is easy to take for granted in developed countries because the process of how clean drinking water gets to a household tap is hidden. In Sydney, 80% of drinking water supply comes from the Warragamba Dam. The rest comes from a variety of sources, including a small amount from the Kurnell Desalination Plant. Sydney Water, the supplier of Sydney’s drinking water supply, follows the Australian Drinking Water Guidelines (2011) to provide a clean source of water.
The first principle listed in these guidelines states “The greatest risks to consumers of drinking water are pathogenic microorganisms. Protection of water sources and treatment are of paramount importance and must never be compromised.” Therefore, ensuring access to clean water supplies is also important on a bushwalk. Sometimes this means searching for clean sources or water, and at other times this means treating water.
In the end, the choice to treat or not treat water is a personal one based on knowledge of how clean the source is and what the individual’s immune system can handle. If unsure, err on the side of caution and treat water before using.
