March 18 – Save & Use Grey Water

1Then Jacob went on his journey, and came to the land of the sons of the east. 2 He looked, and saw a well in the field, and behold, three flocks of sheep were lying there beside it, for from that well they watered the flocks. Now the stone on the mouth of the well was large. 3 When all the flocks were gathered there, they would then roll the stone from the mouth of the well and water the sheep, and put the stone back in its place on the mouth of the well.” ~ Genesis 29: 1 – 10

Go grey for a greener world / “Grey is the new blue”

Every day we flush hundreds of litres of reusable grey water down the drain.  Using grey will enable you to save potable water and be part of the sustainable water use lifestyle.

So what is grey water??? Grey water is water that has been used for washing – whether from the bath, shower, basin or washing machine. Grey water can be used to water household plants, gardening, landscaping and flushing the toilet. The easiest way to use grey water is to manually use a bucket to remove water from the shower or bath

Guidelines for using grey water:

  • Never store grey water for longer than 24 hours.
  • Choose biodegradable and environmentally friendly personal hygiene and cleaning products (those used to clean the bath and basin) to prevent a build-up of salts in the soil.
  • Never reuse water from your kitchen sink or dishwasher.
  • If you wash cloth baby nappies in your washing machine, divert the water to the sewer. You should also do this when using chemicals like hair dye or bleach and if someone in the household is sick.
  • Allow grey water to cool in the tank before irrigating the garden. Hot water can kill off beneficial organisms in the soil.
  • Never allow anyone in your home, including pets, to drink grey water.
  • Grey water shouldn’t be allowed to pool on or run off paving – make sure it soaks directly into the soil.
  • Don’t overwater plants just because you have the water. If there has been a lot of rain, divert the grey water to the sewer.

Don’t mix grey water with any harvested rainwater.
