Client: Pinecliff Horse Stud
Task: Design and construct the worlds largest organic waste management system
Project Manager: Alan Duke
With 1200 tonnes of manure even composting could not create unacceptable levels of methane gas in the bid for ecological sustainability. To avoid this Pinecliff has installed a state of the art worm farm with the same volume as an Olympic Swimming Pool. All waste on the property, animal and human, is disposed of and treated onsite in the Worm Farm and the by-product used as organic fertiliser. The Pinecliff Worm Farm is the largest and most advanced waste treatment facility in the Southern Hemisphere. The worm farm rapidly breaks down matter and produces a by-product (worm castings) that is then used as an organic fertiliser for use in pasture and track maintenance. The two storey worm farm is buried under the ground to ensure the aesthetic of the landscaping is maintained and to maintain a constant temperature, operating like a rainforest floor as it filters water through the organic material stored on the false floor.
All reclaimed grey water including the backwash that comes from the equine swimming pool passes through the worm farm and is sent to the wetlands for further filtration and polishing before reuse.
