Personal Reflection (NEWater visit)

Hi, this is Preston here.
From this NEWater Plant visit, I have learnt at least 3 things:
1) Water is expensive and very difficult to get,
2) We could lose our water supply if we do not conserve water and find ways of retrieving them,
3) We must learn to appreciate with what we have and continue to save our water.

Also, I have learnt 2 concept from today's visit:
1) In order to make sewage water clean and safe enough to drink, it has to pass through two stages: the ultrafiltration and the micro-filtration. After those stages, the water is actually safe enough to drink,
2) To ensure that the water is really clean, it goes through the ultra-violet treatment to kill all other bacteria or other unwanted 'pests' from the water.

1 interesting thing that I have learnt today from the trip would be that the ultra-violet treatment was actually the cheapest item that they have in the factory! I always thought that ultra-violet treatments were very expensive, as they needed electricity and the light bulbs to run it.

As a student in Singapore, I can save the amount of water that I use everyday. Also, I can reuse the water that were used to mop the floor to flush toilets. I can also hold a campaign to teach younger students to conserve water in a right manner.

That's all that I have to say. See you next time!
