Actually we can recycle waters and NEWater is the brand name given to recycled water produced by Singapore's public utilities. More specifically, it is treated waste water (sewage) that has been purified using dual-membrane (via micro-filtration and reverse osmosis) and ultraviolet technologies, in addition to conventional water treatment processes.
We can also conserve water . And the ways to do so are actually very simple . They are :
1.When washing dishes by hand, don't let the water run while rinsing. Fill one sink with wash water and the other with rinse water.
2.Some refrigerators, air conditioners and ice-makers are cooled with wasted flows of water. Consider upgrading with air-cooled appliances for significant water savings.
And many more . So thats all about conserving water resources .
