This was a complicated system that involved using a 4" pipe as a surge tank before the laundry water dropped into the garden. From the washer we ran the greywater pipe through the wall, in between a flagstone patio, and to the edge of the garage. We laid the 4" pipe alongside the garage, between the house and plants to be watered. From there the greywater connections went into a large valve box so the water could be diverted into various zones. Three Sweetwater instructors did this installation as Dreamscape work crew instead of a workshop. It was a lot of fun putting together. The project was completed in August 2014.
