13. Module “Greywater Distribution in Mulch Trenches”
advantages of using organic material for sub-surface distribution of greywater:
it‘s locally available (coconut fibres, rice husk, wood chips, bark chips, ...)
use of organics (agricultural scraps, ...) that may otherwise not be used,
it doesn‘t require costly materials (PVC-pipes, gravel, ...) to be used,
it‘s flexible in construction and can easily be replaced in the event of decomposition and clogging,
use for co-composting afterwards
