You might want to consider the following:
-bigger than 5 gallon holding tank, perhaps a larger plastic bucket or somesuch, as the discharge from the washer may overwhelm or overflow the 5 gallon version
-separate & independent branched drain system for the shower stall
-since water is not pooled anywhere in the lines of a properly installed branch drain system, and since the lines should be buried below the frost line, winter weather should not be a problem. Just to be safe, maybe bury the lines another ~6" below the frost line in your area.
-used women's nylon stockings have been found to be good filters for lint, hair, etc..
- read Art Ludwig's books on branched drain grey water, et al, available from Amazon.com or probably at your local library or via inter-library loan
-these systems are amazingly inexpensive, no moving parts, gravity powered, and failsafe if done right
