Recycling Water

I did my research on recycling water. As our population grows, there are more pressure on the fresh water supply. One of the solution to solve this challenge is to recycle and reuse our grey water. Countries like Australia is currently the leader of this movement. Australia suffers drought and will continue do so for the next 7 - 10 years, thus they implemented a 2.5 billion dollar project to build some of the world most advance water treatment plant. These water treatment plant will draw existing treated water from water filtration plant and resupply to the local region. Other places like California are recycling their water, treating it through filtration and disinfectant to use for irrigating publick parks, and using it for flushing water in public areas. 

Although there are many advantages in recycling water, there are still many issue concerning the safety of using these water. Many cities, consider reclaimed water undrinkable, many chemicals, parasites and bacteria are unable to be removed from the filtration and chlorination processes. 
Another way of recycling water is harvesting and collecting rain water. This method is very useful in urban areas, where water is collected to be used in everyday household activities. At the same time, contaminates might contaminate the water, bird feces, urban pollution particles and mosses may contaminate the water.

Recycling water is a great solution as our population and city continue to grow, our fresh water supply will always be in strain, therefore reusing our water is very important.
