Permaculture is the idea of contained sustainable agriculture that requires no external inputs – all energy and required input is generated by the permaculture system. Some enterprising people have turned their backyard swimming pool into a permaculture setup that is based around aquaculture.
Watch the video for some neat views and an explanation of the system. You can also find out more from the garden pool website.
The garden pool combines:
solar power â€“ harnessing and storing the sunâ€™s energy
water conservation â€“ using less water and recycling waste water
poultry farming â€“ raising chickens
aquaculture â€“ raising tilapia fish
hydroponic gardening â€“ growing fruits, veggies, & herbs without soil
organic horticulture â€“ using natural methods to control garden pests
aquaponics â€“ the symbiotic cultivation of produce and fish in a recirculating hydroponic environment.
biofiltration â€“ natural water filtration method using biochemistry and duckweed.
Using the same principles employed in constructed wetlands, puRE treats wastewater through six stages. Wastewater first flows into closed treatment tanks during the first two stages before reaching four separate purification cells in stages 3-6. These purification cells contain several species of aquatic plants and animals which remove pollutants naturally and even allow for small-scale food production as a by-product. The solids from the wastewater stream are filtered and directed to a communal methane digester, generating another bounty for its users – power.
