1. I learn how NEWater is made, what are the four
water 'taps' in Singapore and why we should
conserve water.
2. I learn that the four national taps are the
local catchment water, imported water,
desalinated water and NEWater and also learn
that the process of making NEWater from
microfiltration to reverse osmosis and
finally to the ultraviolet tubes.
3. NEWater is only for small consumption and
not be drank daily.
4. We could reuse water by reusing the water we
used for cleaning our cloths to water the plants
we grow.
