A while back, I started using greywater, waste water from my clothes washer, to flush my toilet. The system works well, and saves TONS of water, but I still wanted some way to filter the water first, preferably with a biological system.
I keep a large aquarium, and I also compost, so I thought that some of those same principles could be applied in my laundry room.
So, I converted my laundry tub into a constructed wetland!
To get started, you will need:
Space next to your washer
A laundry tub
Sand, pebbles, stone, dirt
Your wife's permission!
Step 1: Work Area - Tub Space
To get started, find the space next to your clothes washer.
In this space, I originally had a wash tub, but replaced it with a large barrel to hold laundry water. The original water-lines and drain are still there.
In this case, we are NOT going to use the drain, but rather, install a new pipe that leads to a water storage unit.
Measure where the center of the drain is on the laundry tub, and then mark that same distance on the floor. Drill a hole through the floor there (making sure a floor crossmember isn't directly below) with a 2" hole saw.
Slide a drain pipe through the hole. If you have a full basement, you can slide the pipe in from below later. If you only have a crawlspace, like I do, you will have to put a short piece of pipe through BEFORE you install the laundry tub.
