Reflection on the NEWater trip

  1. What are the 3 key takeaways from today’s visit?
  2. Name 2 concepts that you have learnt today during the visit.
  3. What is the 1 interesting thing that you have learnt today?
  4. What are the things that you can do to help with water conservation in Singapore?

Firstly Singapore has 4 national taps. The four national taps are, Local Catchment of Water, Imported Water from Johor Bahru, NEWater and Desalinated Water. NEWater currently covers 15% of the daily usage of water in Singapore.

We learnt that the used water goes through a couple of processes to clean it until it is safe for us to drink. I also learnt that ultra-violet light filtration is so strong that no living organism that passes through it is able to stay alive.

There are two contracts between Malaysia and Singapore. One expires next year and the other expires 51 years later. Also, ultra-violet light is a 100 times stronger than that of the sun.

One way is to don’t leave the tap running unnecessarily. A very good example is when you are brushing your teeth. Instead of leaving the tap on, use a mug. This will reduce the amount of water usage. Another way is to fix any leakage ASAP. A dripping tap wastes at least 5500 litres of water every year. That’s enough water to fill a pool every week for the whole summer. Fixing your dripping tap could save you over $50 a year.
