@LadyLocust all you need to use is low or no phosphate cleaning/personal care products and it is fine for the grey water system and for watering fruit and berry trees with. The trees thrive just with the grey water we have found. You just don't use things like bleach or excess ammonia as it kills the good bacteria in the grey water tanks.
Obviously the water from the kitchen sink and toilets go to a septic tank as they are considered black water and not suitable for gardens and trees.
