While that is very interesting, it does not answer my question. I will attempt to rephrase it. Commercial private entities will enter into such schemes, legitimately from their perspective, not from the joy of building new infrastructure, but because that infrastructure in commercial terms represents a revenue generator for them. Other than that, they do not do so from the joy of providing drinking water per se. It strikes me that any kind of credible value for money analysis must factor in that revenue which goes to a private entity because, as Ms Tallon pointed out, it will be doing the running and operating, as against that revenue coming back into the public system. I simply am asking Ms Tallon whether the Department factors that in and if not, why not? If it does, as I hope it does, what is the scale of that return into a private purse rather then back into the public purse?
