My first thought was grey water filtering into reed beds. Then I thought, if it floods it would all get washed out. So my ideas went to raised beds in something that would not be eaten by termites.
ICBs that can be cut in half make great wicking beds. Two purposes would be filtering the grey water and also providing vegie gardens. Also having it filter through a food compost would provide nutrient rich soil.
Another idea was recycled bath tubs from refuse tips if they can be shipped up there.
Can you also let me know if the idea of slow sand filtering has been raised for the Cape York communities in the past? I don’t want to spend a lot of time planning and researching if it’s been proposed previously.
Thanks for the feedback.
