Good grey water filtering plants

I agree with Randy about the ill-fit of bulbous plants for this use. I have certainly seen wet-loving iris grow immensely in one season - certainly enough to act as a sink for grey water impurities. The problem is the seasonality of most bulbs' (corms etc) growth: when the iris die back in winter their ability to clean grey water would be negligible... Crinum could be better since they can be evergreen but a grey water system would seem to require plants that are vigorous enough to be invasive and I don't think even evergreen Crinum could keep-up with the needs of a grey water system...
