In some parts of the world, the term “wastewater” is not a thing. With increasing droughts in urban areas, people are becoming much more familiar with the terms Gray Water (greywater) or Used Water as better definitions for water that’s used for everyday tasks such as dishwashing, showering, and even laundry. Even if you can’t yet implement safe residential Gray Water systems into your home, keep reading! We have reviews on greywater friendly all-natural soaps listed that we recommend for all households.

Being an Oregon-based site, most of us at EcoKarma haven’t experienced water shortages firsthand. However, we are quickly learning to not take the water we do have for granted. Responsible water usage is a huge part of having a more sustainably balanced life.

To jump right into things, we are going to look at some grey water safe products and then we will cover some common questions about gray water.

Best All Natural Hand Soap Reviews

Handwashing sinks are a great place to start when building residential gray water systems. Most of our favorite soaps offer a large refill option – meaning less plastic waste! We’ve linked to them, but we also suggest trying smaller bottles out first to find one that works best for you and your family.

1. Puracy Natural Liquid Hand Soap

This Lavender & Vanilla plant-derived hand soap is made in Austin, Texas, and is one of the highest-rated hand soaps on Amazon. The clean ingredients foam up quickly for a good lather, and the soap itself is much thicker than some all-natural hand soaps, making it easier to use less of it.

Puracy has a great reputation for making soaps, body care, and hair care items, that are effective yet also safe for you and your water.

2. Meyer’s Clean Day Hand Soap

But what if we told you that you could use Dr. Bronner’s Pure Castile soap to wash your hands, and your mouth? No, not because you said a bad word, but because you want fresh breath!

Personal anecdote time! My first encounter with eco-friendly shampoo and conditioners was with a clearance bottle of Renpure on a Target endcap a few years ago. I was hesitant, as I had heard that they cleaned, but did not moisturize, and dry hair had recently become a problem for me. I know use a Renpure cleansing conditioner regularly to help moisturize and give life to my haphazard curls. This Argan Oil set is great for all hair types.

What Is Grey Water?

As stated above, gray water is a kind of used water from household tasks that can be safely reused. It doesn’t contain sewage, and if you treat it properly it can be repurposed in a variety of ways. It can even be used as a way to irrigate your own garden as a form of recycled water.

gray water

A manual diversion and collection of water from some of these appliances and pipes is the only way to safely collect gray water. We suggest starting small. Try a gray water system in one sink in your house. Designate it as so, and make sure to only use all-natural soaps in it.

In some areas dishwashing water can be used, so long as it doesn’t contain too much organic matter. Make sure you do your research and implement proper filtration before using this water.

How Does the Use of Grey Water Differ from Water Reclamation?

Many might think that gray water doesn’t sound much different from the use of a water reclamation system that are much more common. So how does the use of greywater differ from water reclamation? Reclaimed water has to be treated before it can be reused. Often it is contaminated by harmful toxins, sewage, and chemicals, which all have to be removed. A proper greywater recycling system can be used without any sort of filtration or chemical treatment.
