Dirt Water

I recently went to Makro and purchased about 6 ( 6 Packs ) still water, as we all know that Cape town is close to Day Zero and since everyone is basically telling us not to drink tap water as it is not purified, ( I still believe this is a money making scheme) but never the less having two kids I can risk them getting sick, so for about close to a year we only drink bottled Aquelle Water ( I have now recently changed this to Valpre). Living so far from Makro, I am thirsty I decide that I am now going to drink a bottle water, to my shock yes I saw dirt and tiny little particles floating in the water, so thinking that maybe its just one bottle, no its not its all, so i asked my fiancé to do a little test, I took a bottle of Valpre, Aquelle and tap water to see the difference and Viola??? guess what Valpre came out on tops with the natural spring and Aquelle water tasted exactly the same like tap water? So i ask you Aquelle??? what is the point in me spending close to almost R300 a month on your brand of water when this indeed is tap?? or please explain your little particles that are floating around.
