I've got a leach field after a septic tank in zone 9, dry Mediterranean climate. Soil is heavy clay over rock, alcaline ph 8.5. Leach field is now a 25 meters open canal with permanent water.
I am allowed to clean the canal and do some earth works next Monday.
My plan is to cross the canal a few times so canal length is 3x or 4x what I have now. Then cover with gravel, fence it and plant something.
My goals:
Stop current mess
Not trying to reuse water
Get poultry forage and/or compost material from green filter plants that use the resource.
I've thought about comfrey, canna,thypha and
?
