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
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.
Step 2: Install the wash tub
Hook up the water lines to the faucet.
Glue a threaded connector onto the end of the new drain pipe, so that it can thread directly to the washtub drain.
Thread the new pipe into the bottom of the wash tub.
