Water sustainability, a global issue. In the past two weeks, the class has been formulating our research question that would be both from a global perspective  as well as be interesting and help others gain insight as to why water sustainability is so important and how we can ensure it. This week, we finalised the research question, and proceeded to break up into groups to do case studies on how different countries employ different methods to ensure water sustainability in their country. As for my group, we focused on our home country, Singapore. Upon researching more on NEWater, Singapore's prized method for water sustainability, I found out many new things in the process. For example, that 30% of Singapore's potable water supply comes from NEWater, and how energy consuming running the NEWater plant is. Also, that more and more NEWater plants have been opening, evidently showing how successful this venture has been.  I feel that especially for Singapore, a small country, coming up with methods for self sufficiency is pertinent since we should not be relying on other countries to supply us with one of our most basic resources. This would then cause us to be put in a very vulnerable position. Thus, much emphasis should be put on research and development to improve the technology required for water purification processes in Singapore. Genevieve
