I would add to willows, for use in a constructed wetland (mimicing a 
natural system), river birch (not the commercial cultivar), and upland, 
wild cherry because they grow so vigorously and can absorb nutrients to 
produce wildlife food, shade and habitat. I would add elderberry as it 
like a lot of water and produces fruit. Same for eleagnus, despite its 
invasiveness in some regions. Possibly wild persimmon and wild locust,
upland or on swales. In a pretreatment lagoon, pond or deep wetland or 
all three connected (best) i would establish the following:
duckweed, cattails, water lilly, papyrus and where it can survive the 
winter, water hyacinth. These five plants can handle a measured, regular 
influx of waste into a system, are very durable and will produce crystal 
clear water, especially using hyacinth in the last treatment stage 
(maybe enclose it in a greenhouse).
