New to grey water usage, where do I start?

Hi,

We are currently in the planning stages of building our new home. It will be on acreage outside of building codes. We would like to reuse grey water. Where do I start to learn the process?
Currently we are living in a ttrailer on the land. We have a holding tank for grey water. Every time I empty it smells! Is this what to expect when reusing?

Our future usage would potentially be from laundry and bathing. Not sure about kitchen sink due to grease. We live in zone 7A so we do have some freezing in the winter, plus we plan to have a pseudo greenhouse inside and hope to use some grey water there if it does not smell

Any advice will be greatly appreciated.

Thank you
Jim

Usually you never hold grey water in a tank, because it gets smelly! It is so simple to plan but you must think of the height of the tubes that it has sufficient slope.
The other thing to mention is that in areas with a harsh winter things might be a bit different.
We did our grey water system like this:
Grey water goes out maybe 2 meters away from the house (you don't want that much moisture close to the house) and then into a mulched channel were ornamental gingers grow into a pond with plants. The whole thing is close and uphills to the vegetable garden in the hope it keeps it moist. It looks absolutely good at least in summer when the gingers bloom, but in winter they died me down.
