Grey water recycling is the process of saving and reusing water that flows out of the house. Grey water can be from any source - except the toilet. There are many potential uses for grey water; however, the most popular use of grey water is for irrigating or watering a yard or landscape. But, you can also use grey water to flush your toilets. Creating a grey water recycling system is a great DIY project, and this simple how-to guide will walk through the basics of making one. Let's get started.

Step 1 - Choose a Grey Water Source

First, you'll need to choose a source for your gray water. You can tie into a basement or bathroom sink, the outlet hose for your washing machine or any other source of water in your home. As long as the water source has a drain, you can use it for your grey water recycling system.

Step 2 - Tie into the Drain Line

In order to tie into the drain line, you'll probably need to use a hack saw to cut the drain pipe. Then, you'll need to attach a T-coupler or other connection fitting so that you can run the pipe from the drain line to your collection barrel. When tying into the drain line, remember to use PVC primer and PVC glue on all the connections so the fittings won't leak.

Step 3 - Run Pipe

After you tie into the drain line of the gray water source, continue running pipe to the area where the collection barrel be located. If possible, try to run as much of the PVC pipe below ground as possible. Just remember that you'll need to bury the pipe at least 12 to 18 inches below the surface of the soil to be meet most local building codes.

Step 4 - Set Up Collection Barrel

Set up your gray water collection barrel by placing a 55 gallon barrel or drum on top of three concrete blocks. Place the concrete blocks side by side and simply set the barrel on top of them. You'll then need to cut a hole in the side of the barrel so the PVC pipe from the gray water source will be able to pass into the barrel and allow water to flow into the container.

Step 5 - Connect Grey Water Pipe to Barrel

Connect the PVC pipe from the drain pipe on the gray water source to the barrel. Simply run a piece of PVC pipe into the barrel and use PVC cement to seal the edges around the pipe.

Step 6 - Use the Grey Water

Once you have connected the PVC pipe from the source to the barrel, the waste water should now run into the gray water collection barrel. You can then use it to water your lawn, wash your car, or anything else where you don't need sparkling clean water. You may also want to install a spigot on the front of the water barrel so that you can attach a garden hose to it.
