Looking for easy gray water suggestions in wet climate

Hi,
I live in the PNW and have been using non-soapy kitchen gray water to water the garden and plants during the summer. Now it's the rainy season so everything's getting plenty of water.

What would be the best way to continue using our gray water during this time that doesn't involve an extensive plumbing project? I collect it manually in a tub and we generate 2 gal/day.

Some ideas I had but am not sure about:
- create a rain garden / pond (more of a long term project)
- dump it on established trees/shrubs (not sure if it'd be too much water or not)
- occasionally water a covered compost pile?
- use it to flush the toilet (this would get a little laborious over time)

I'm new to this and want to see what else I might be missing.

Thanks!
Roger

Most toilets use more than 2 gallons per flush, so if you are only generating 2gals per day. that would only be 1 flush. I really don't see how that is laborious. when itis only a once a day thing.

You could plumb in a pump to pump it to a toilet, but yes, most toilets flush more than 2 gal/day.

I have been researching Sand Filters so, once the water is cleaned, I guess it could be used for a lot of things- clothes washing? Toilet flushing? Store it and use it when the garden needs it?

Here's a link to Sand Filter system:
