We have a lot of customers who use a greywater system at their home. It’s a smart thing to have here in the high desert where climate change is only making things more arid. If you use greywater, it’s important to use soaps that are greywater safe, and we’ve got plenty of options.
What is greywater?
That’s the relatively clean waste water collected from sinks, showers, washing machines, dishwashers, etc. It’s an excellent water source for plants. But in order for it to work safely for irrigation, especially for gardens, you have to be careful about what kind of soaps and detergents you’re using.
What makes soap greywater safe?
In order for a product to be compatible with greywater systems, it can’t contain much salt or boron. A lot of soaps use salts for a surfactant, which lowers the surface tension of water in order to help remove dirt and grease. And while surfactants with sodium are perfectly safe in normal applications, they don’t work for greywater systems because sodium builds up in the soil and changes the pH.
Boron and chlorine bleach are also incompatible with greywater systems, but we don’t carry any products containing those two ingredients.
