Quite impractical to use a sink over the toilet bowl.... fine if u want to wash your hands... but what if you want to handwash your clothers in the sink? Won't it overflow?

I think it meant for just washing your hands. Not sure if there would be another sink for other stuff. I think they should just channel potable water from the rainwater collector into the cistern for flushing. Next to showering, toilet activity uses a lot of water. So this way, can cut down on water bill.

Shower water also can channel to the lower floor collected in the toilet bowl and ready to use for flushing.
Then all the water will then be channel to be recycle as NEWater and back to us again.
Very environmental friendly indeed! haha...

Yes, there is plan to connect Punggol Mrt to Pasir Ris MRT.  MRT will stop at Punggol Central near Riveria MRT.   Not sure when it will start construction.

Not highly recommended, I wash my son's backside after he poos in the potty in the shower. If water collected from this source, sure smell like funny.
