If what I know is correct, Singapore is recycling its water from sewage water systems. They are drinking water that are just recycled. How safe is the water to drink that was taken from recycling system? Can the chemicals mixed in the recycled water be harmful in the human body?

To answer your question in broad terms:
There is several usage of water. Water is used not only for drinking purpose but for several purposes water is used. The recycled water can be used safely under some of the circumstances given below namely:
Recycled water can be used safely in toilets
Recycled water can be used safely in gardens
Recycled water can be used safely in car, bike and other metal washing
I feel taking the world statistics of recycled usage into count Singapore has only a least percentage of making use of recycled water when compared with countries using recycled water.

Norman, I just did a brief Google search and found this comment about Singapore's recycled water in U.S. Water News Online: "The reclaimed water, called ''NEWwater,'' has been touted by international experts as good enough to drink, being well within the drinking-water standards specified by the U.S. Environmental Protection Agency and the World Health Organization."

If true, that pretty well answers your questions, does'nt it?
