Using greywater to irrigate your garden or plants can definitely save you a lot of money from watering using a clean drinking water. However, depending on the content that the greywater carries, it might not be eco-friendly to use it for a longer period of time.
As we already know, untreated greywater contains different chemical compounds from household soaps and laundry detergents. These chemicals can contaminate the soil, thus altering a lot of properties that a healthy soil should have.
However, there are a few cleaning products that are compatible with greywater. By using eco-friendly products in the house, you can safely use your greywater to irrigate your gardens without having to worry about any harmful toxins.
