okay, this is the idea:
raw sewage
water ( with
poop and
urine) flows into a
concrete reservoir, filled halfway with gravel. it contains plants like reeds, iris and cattail and has an overflow. the idea is that the raw
humanure gets absorbed by the plants, and the dirty water will flow over to basin no. 2.
basin no. 2 is a similar basin filled with rocks and reeds. it has an overflow to basin no.3.
basin no. 3 is again similar but has gravel in it. the overflow of this basin goes through a perforated barrel filled with sand and smaal gravel. this goes into a
pond where it will be purified my sweetwater clams.
