Water from your home via your washing machine, shower and bathroom sink can be brought into the garden throughout the year. 
This is an exceptionally good way to water deciduous fruit trees as well as shrubs and many other plants.

I can install laundry to landscape systems (bringing water from your washing machine to the garden) or branched-drain systems (taking water from the shower and bathroom sinks with the use of gravity to the garden).

Care must be taken to see that

  1. you have the appropriate slope — from these home fixtures to the garden, as well as in the garden.

  2. the soil in the garden is friable enough to percolate the water into the ground at a reasonable rate so that water does not remain standing on top of the garden soil.
