Filter your Laundry Graywater with Marsh Plants!

Step 5 Hook-ups

Now, you can put the washing machine hose back in to the laundry tub.
When doing laundry, the waste water will irrigate the plants, filter through them, the sand and gravel, and down the drain to the other components of the existing greywater toilet-flushing system.

Make sure to use an eco-friendly laundry soap, and don't use any harsh chemicals, like bleach.
I do still have a dedicated laundry drain right behind the washer. If I did need to, I could always temporarily switch the drain hose back that original drain.

Is bleach a harsh chemical? In the concentrations used for laundry, the plants may not mind it that much.

I get itchy skin if bleach is used on my clothes.
Same with chlorine pools.

Half the problem is that people tend to use TOO MUCH of household chemicals.

For me, it's just easier to not use them at all.
