Open House at Ngee Ann Polytechnic (8 January 2009)

Learnt something new: Grey Water! Black Water!
Ah! Isn't water transparent? oh yes, it's still transparent, but comes in different shades and content as it's no longer pure. That's where water treatment comes in... Nevertheless, was told that this kind of water treatment requires some infrastructure configuration in order to collect the different kinds of waste water (which are currently mixed during the collection process).
