What is grey water?
There’s three types of water.
White Water – This is clean water. It comes from your tap and can be used for drinking and food preparation
Grey Water – This is a form of waste water, but it never comes in contact with human waste. This water typically comes from sinks, showers, baths and moreBlack Water – Another form of waste water that contains human waste. This comes directly from your toiletSlide3
What is grey water?
Greywater may contain traces of dirt, food, grease, hair, and certain household cleaning products.
Greywater may
look “dirty,” but it’s a safe and beneficial source of irrigation water in a yard or garden thanks to the nutrients in the water from soap and food waste.It’s great for yards because plants love it, and it keeps the water from potentially polluting rivers, lakes and estuaries while promoting reuse and sustainability.Slide4

What is a greywater system?
Greywater systems help you get the most out of your water through reuse.
Typically there are three types of greywater systems
1. Manual Bucketing – This is just like it sounds. Filling up your own buckets and barrels with greywater and manually feeding your landscaping and plants2. Diversion – Diversion is more permanent than bucketing. Diversion uses plumbing for subsurface irrigation to water throughout your yard
3. Treatment –
This is serious. Treatment is the most expensive, but will rid the water of unwanted chemicals through filtration. The filters allow for the most different uses after treatment is completed. Slide6

What kind of system is here?Slide9
It’s a treatment system!
At this house a treatment system is set up to feed the nearby garden. The water is treated through a sand filter before reaching the garden.Slide10
How do I make my own greywater system?
If you’re only beginning with greywater, manual bucketing is an easy way to start. You can simply unhook the waste water hose from your washing machine and place it in a nearby sink to collect in a bucket.
If you want to look into a diversion or treatment system, it’s best to consult a plumber to ensure you don’t damage sprinkler systems or gas lines.Slide11
Now let’s see how the system here works
With two five gallon buckets of colored water you’ll see firsthand how water from the bathtub feeds the garden after passing through the treatment filter.
