Exactly what type of greywater is okay for watering vegetable gardens?
You can use the drinking water you capture while waiting for the water to heat up in the kitchen and bath as well as rinse water from washing fruit or vegetables. The EPA recommends you don’t use greywater from the kitchen, bath or laundry (i.e. water with soap residue) on a vegetable garden if the crop is to be eaten raw or uncooked.
