Water Recycling: Save Water at Home by Using Greywater
It’s no secret that water is California’s most precious and elusive commodity right now.
Water restrictions have been enforced, showers have been shortened, and green traditional lawns have become a source of environmental concern.
If you’ve already gotten a hang of the one-minute shower, there are other ways like water recycling to reduce your water-related footprint.
In this article, you can learn the benefits and techniques for saving greywater from your laundry machine, sink, and bathtub as well as where not to use water recycling.
What is water recycling and greywater?
Disclaimer: We have outlined the process for greywater and its benefits, but please do research for your area to decide if it is right for you.
There’s a ton of reusable water going right down your drain in the form of greywater—this is relatively clean run-off water from baths, sinks, washing machines, and kitchen appliances. While this water isn’t suitable for consumption, it can be a vital resource for sub-surface irrigation. Greywater should NEVER touch the edible part of a plant—meaning that veggies aren’t good candidates for greywater irrigation.
Keep in mind that greywater may contain traces of dirt, food, grease, hair, and cleaning products. This results in the need of a filter before releasing it into the garden due to health concerns. However, what it lacks in looks, it makes up for in benefits for plants and lawns.
Greywater is not water that has come into contact with feces, either from the toilet or from washing diapers.
Why should I recycle my water at home?
Reusing your greywater keeps it out of the sewer and septic system. Water recycling provides a dependable, locally controlled water supply for your use at home to save money and help the environment.
How can my recycled water be reused?
The main takeaway from greywater is its value for home irrigation.
Water Recycling: How Does it Work at Home?
Greywateraction.org is working to create sustainable water culture for the future. We have used their website as a resource to learn more about water recycling and greywater use. This collaboration of educators believe that “decentralized conservation measures can play a critical role in drought resilience, climate adaptation, and the return of healthy stream ecosystems.”
Laundry to Landscape: If your laundry room has an exterior wall, the greywater pipe can be laid to travel directly outside for irrigation. If your laundry room has an interior wall, the greywater pipe will exit through the floor and travel through the crawl space below.Crucial Tip: A biological filter must be installed or you will only be able to use the rinse-cycle water.

Now what should I do after water recycling?
Water recycling can be a great way to keep your garden looking lush, but it’s doubly helpful to have a more luxurious and sustainable outdoor landscape to start. Switching to a drought-tolerant lawn is a practical, eco-conscious way to lower your water use while even increasing your curb appeal and a major initiative as one of our eco-friendly landscape construction techniques.
Some of California’s most beautiful natural landscape comes from the desert—from the beautiful clay palette to the bursts of color from succulents and cactus flowers. Recreate this setting by using native plants that thrive in an arid climate. Succulents like Panda, Desert Willow, and California Fuchsia require very little upkeep and are perfectly happy drinking all that greywater we talked about up there
Want to get a little creative with all that slate and clay? Make an outdoor oasis using natural stone pavers, complete with a fire pit—or even an outdoor kitchen. Hang a vertical garden along the walls to create a living work of art. The result is a multi-functional living space that looks as good as it makes the environment feel.
