good information

There is no rectriction on the plants that can use grey water, However if u r using these plant for cleaning / treating grey water then consult ur local nursery and ask about the following parameters: 1. The plant should not consume too much of water, otherwise there would not be much grey water left post treatment. 2. Plants should not have strong roots which can damage ur civil structure. 3. They should be in position to grow with even small soil contents!

In southern CA the trees are stressing big time. It would be terrible to lose such treasures. I recommend focusing on established large plants such as trees and working down to smaller plants.

Wetland plants are often used in ecological disposal systems, with the goal of the system being to use up the water and not necessarily irrigate anything (wetland plants soak up lots of water). In a greywater irrigation system you can irrigate any plants that like frequent irrigation. Be sure to use plant friendly products (low in salts and free of boron). Typically larger plants like trees, bushes, etc. are easiest to irrigate with the simple types of greywater systems.

Good luck with your system!
