Can separate Gray/Black water at discharge?

[stgerdonly]

Any thoughts on how I can separate gray water to drain in a gray water well, while keeping sewage in the holding tank? We have a 1978 Argosy 30 rear bath model and not sure if this is doable... Any thoughts?

You have two separate holding tanks (gray water and black water). Each has it's own dump valve and can be emptied without affecting the other.
