Many large rabbitries provide drainage pits under the
rabbit cages that allow the manure pellets to remain as the
moisture soaks into a drainage system and is removed
from the building. Figure 19 shows a method for construction
of these pits. The drainage tile in the bottom of the V
has many holes in it so water and urine soaking down
from the rabbits will enter the pipe and can be led out of
the building. The layer of gravel above the pipe keeps
the holes from being plugged and the pipe from filling
with sand. In areas with well- drained soils, the perforated
drain pipe may be unnecessary. The sand is installed to
provide a firm, level surface on which the manure pellets
can be collected.
