Community Garden and Reclaimed Water

Our project is using greywater for landscape irrigation, likely 100%. The project will have a small community garden where residents can grow their own food for consumption. Because these are edible, we are not using recycled greywater for the community garden. Has anyone had experience with excluding this type of landscaping from the irrigation calculations? Nearly 100% of the landscaping will not require permanent irrigation systems EXCEPT for this small garden. It is still unknown if the community garden will be hooked up to a potable water irrigation system or if it will be hand watered and managed through the residents and/or a third party. Thank you.
