gray water - cleaning the canvas
Preparation for a gray water biofilter
I am planning on building a biological gray water recycling unit in my garden. So far the plan is a double wall, a long trough in other words, filled with gravel, topped with plastic baskets full of plants, through which my kitchen sink water will seep and eventually exit into the pond-tank-pool described before, but first there is so much back breaking rearranging to be done !
moving planting bench into the shady south alley, 2 meters wide.
moving the old sandy compost into the north alley, 1m wide
one compost chamber is now ready to move to its new location
moving the compost chamber and bulk compost to new location
The composters stood on the concrete driveway, and now they stand on another old concrete slab. This helps prevent humanure composting from contaminating the soil. I have also added a base palette for aeration, because I want this compost to be hot, fast and effectively remove pathogens quickly. I'm not into frequent turning of the compost though, so I reach a compromise, with excellent aeration, high N (urine) and after its collapsed I will move it to second chamber and start a fresh heap. The older compost that will previously have been in the second chamber will be bagged, inoculated with mushroom mycelium and left in the cool south alley for a year.
Chambers in the new spot
On the left is the new heap, built from lawn clippings salvaged from the park, fruit waste and cabbage leaves from Epping Market, torn up cardboard and humanure, and the heap was wetted with fruit ferment, nettle ferment and diluted urine. On the right is the old bulk compost that I carried over in the wheelbarrow from its previous location.
