Big new technological advancements ?

No, you offered no argument at all: I was trying to determine what your argument was for government intervention beyond 'it's the right thing to do, or, as you say 'it's a waste'. Therein lies the problem: you think it's a waste, i do not. Regulating waste where no harm is done (of course that is a point for debate - which funkydexter, quite rightfully brought up; that advances the discussion) is not for one person - or a majority - to make a decision over another.

Well me saying that I think it's a waste is an argument. So, you think that taking unclean water from the ground, or desalinating seawater, then processing it to make it clean and drinkable, pumping and delivering it to homes, then practically just dumping it into the sewer is no waste of various resources? In my opinion it's a waste comparable to putting a heater outside in the winter to make the city warmer.

And to follow through with my comments, flushing with used water will create unsanitary conditions - that is why we flush with sanitary (or rather 'clean') water.

Would you care to elaborate how reusing water from lets say your bathtub and using it for flushing will make the sh*t and piss unsanitary, or more unsanitary because it's not very sanitary in the first place.
