Willow Wastewater Cleaning
Facilityhttp://www.pilerensning.dk/ENGLISH/index.htm
"Willow waste water evaporation systems which are zero-discharge
systems. Willow trees (and others) evaporate all water and uptake
stuffs. They will meet all new demands in legislation simply because
they have no outlet at all."

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).
