Reclaimed Water: How safe is it to be consumed?
For more than centuries, reclaimed water has been studied to improve its potential use as future water. Nowadays, some regions have been using this water to meet the demand of increased population and to solve the problem of water shortage. Numerous researches have been done to study the feasibility of reclaimed water for potable purpose and already being approved, yet the quality is hotly debated. Nowadays, some regions such as in the United State, have applied the advanced technology to discharged highly treated wastewater into the reservoir which is the vital source of drinking water for public use. This water is expected to fluctuate in future whereby potentially reclaimed water feasible to replace it due to controllable quality (David, Franklin & George 2003, p.1356). For that matter, reclaimed water is able to provide additional source for public. However, further studies should be conducted to ensure that it is safe to be used in arid and semi-arid places as additional water supply. Despite extensive research and advance technology, social hurdles as well as health risks have become the main argument against its potentiality as potable water. It is claimed that, water which origi
There is a need to do much more complete characterization on their properties in order to detect more foreign substances in treated wastewater. As time goes by, there are a lot of improvements gained in this technology, from non-potable to potable purpose. However, some have opposed the idea because treated wastewater may carry low concentration of chemical constituents as well as bacteria and virus transformation. Richardson and Trussel (1997) indicate that only knowledgeable and supportive public will understand the concept and objective of this technology. While, in Windhoek, Namibia well-planned direct potable reuse project has been carried out to store emergency water for extreme situations such as drought (George, Franklin and David 2003, p. Conclusion In brief, reclaimed wastewater is a useful technology that brings a lot of benefits to the world population as it can produce water with almost all quality required. Besides that it also gains recognition from government. This has been justified by the Prime minister of Singapore that it enables to add the country's (Singapore) water supply by reclaiming it to pure and clean water (Singh 2003). In an email communication on 1st June 2005, Mr. The issue on health is raised based on the drawbacks that are being highlighted as above but the benefits of reclaimed water seem to outweigh its drawbacks. Timko (2002) claimed that, there is a high possibility that chemical substances being carried in wastewater and most of the treatment processes are unable to eliminate them.
