What is Greywater?
Greywater is a type of wastewater generated from sinks, showers, and washing machines that can be reused for non-potable purposes. We’ll explore what greywater is and how it can be harnessed for your garden.
Definition and Explanation
When it comes to conserving water and reducing our impact on the environment, greywater is an often-overlooked but incredibly effective solution. So, what exactly is greywater? In simple terms, greywater is used water generated from domestic activities such as showering, bathing, washing dishes, and laundry. It’s called “grey” because it’s neither black (which comes from toilets) nor white (which comes from clean, potable water sources).
Greywater differs significantly from blackwater in both its characteristics and uses. Blackwater is the wastewater generated from toilets and other sanitary fixtures, which requires rigorous treatment before being safely discharged into the environment. Greywater, on the other hand, can be reused with minimal treatment for irrigation purposes.
By utilizing greywater for your garden, you can significantly reduce the amount of clean water you use for irrigation, saving you money on your water bills while also helping to protect this precious resource. In fact, according to the US Environmental Protection Agency (EPA), a typical household can save up to 30% of its total water usage by using greywater for gardening purposes alone.
