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 ...
