I want to put a natural pond in and feed it from runoff of two metal roofs on the house and barn/shop. Is this possible? Is it safe to have animals like dogs, chickens, and ducks to have access to the pond? Does there have to be special filtration for this application? How big would it need to be to be able to sustain itself? The house and the shop will each be about 2000sft.
We are about to build in AL and Passive Solar Design, conservation, and permaculture and food forest and raised beds will be key elements!
