water treatment

At Disney World as I have been told they use water hyasynth. It brings
their waste water up to florida standards for dring water. Any plants
used would have to be able to deal with the waste load all year or have
a large enough volume for buffering during the plant dormacy period.
Disney treats their water in greenhouse for consistant rmoval. They then
compost the plant material and use it in the gardens on site.
