How much are you charged for water usage?

In Singapore, we receive our utility bill on monthly basis.  We trust the computer systems and there are too much tiny figures that is too nitty gritty for us to bother.  Majority are not aware that we are charged with 2 scales.  The water usage is what we draw from the taps ( including sanitary outlets), the unit then breakdown into 2 category for waterborne fee, one into sewerage system and another into waste water treatment.  That is regardless of what purpose you draw the water from the tap for. It is presumed that it will all go back into the waste system.  But in reality, we consumed these water for cooking, drinking, watering plants, washing, etc.  How much was really back into the waste systems, no one ever question. To date we are paying S$1.17 per Cu M, but in actual rate we are paying S$1.45 per Cu M, S$0.28 extra went to waterborne fee.

So next time before you turn on your tap, do think twice because every drop is precious.
