|This is my new Ecobed. Its the same size as the last one I built (Making Ecobeds), but I have made a few improvements.|
|75mm galvanised bullet head nails are used to secure the layers of sleepers together. They are hammered into the timber until they are flush with the surface. The corners are still joined using 2 galvanised 125mm bugle head wood screws.|
water distribution system has an overflow pipe joined to the filler
pipe at the water tanks maximum permitted depth. When the water tank is
being filled (by hand or due to heavy or prolonged rain) the level of
water in the filler tube rises with the level in the tank. As it
reaches the junction with the overflow pipe it begins to flow out of the
bed through the wall. |
This post provides construction details of a similar overflow system built for my latest Ecobin upgrade.
The system is sealed against unwanted infiltration of soil or scoria which might cause a blockage in the overflow pipe. Earlier overflow pipes were protected from blockage using a shadecloth filter. Unfortunately they eventually blocked without warning, and I nearly lost my dwarf lemon tree when the overflow system in its small Ecobed failed. The tree nearly drowned after prolonged rain, but after emergency measures it is now recovering well. Regrettably, I had to sacrifice this years crop of lemons to save it.
|The above picture shows the overflow pipe emerging from the outside of the bed wall.|
|Each top corner has 1 net hook in the adjacent rail as shown above so that the end net can be wrapped around the side netting to close off any gaps.|
