The drainage hose from the washer just goes straight into the trash can. The can usually fills up with two loads of laundry and gets distributed to the shrubs and plant life in the front of the house. I had aspirations of hooking up a hose to the base of the can and letting it be a soaker hose system out front but eh, no big deal. It gets the job done.
I used the Ecos brand laundry detergent, surprisingly available at our local Kroger. I did a lot of reading about the safety issues concerning grey water as far as bacteria and potential chemicals from detergents and am pretty satisfied with my choices. I wish I had a system to use it on the vegetables but don’t trust the safety of the water. I’d love to have a more intensive system in place, provide water for a cutting/dye garden.
