we LOVE water!

Hi! Walter here. I am going to talk about:
The new desalination technologies and other alternative sources to increase water supply in Singapore.

Singapore has been testing new desalination technologies which have the potential to increase water supply at lower cost.

First, is the membrane distillation technology uses waste heat released by incineration plant to boil sea water and collect the water vapor. The salt content in water produced this way can be reduced by 1,000 times while energy consumption is three times less than that used in reverse osmosis. A demonstration plant is expected to be built next year if everything goes well.

Another technology, the variable salinity system, can turn water from the sea, river, stream as well as rain water into potable water. A demonstration plant will be completed by the end of this year. (sorry couldn't find the photo)

These are major step towards reducing dependence on imported water from Malaysia.
"Singapore can be self-sufficient beyond 2061," said Ibrahim, Minister for the Environment and Water Resources Yaacob, referring to the four national taps, including water from local catchment, imported water from Malaysia, NEWater and desalinated water, which will be enough to sustain the city state's growth and development.
