How it typically works is that the grey water is piped into a series of natural filters, so that the result is surprisingly clean water without the use of chemicals. That water (while not drinkable) can be used to water plants.

Do note that to use this system, you must use bio-degradable detergents, soaps, and so on. Non-biodegradable products may be too harsh for your system to break down and could harm plants and wildlife.

Garden System:

Water is piped out into a filtration system series. Here is a common setup:

Course Medium:

Something to catch foods and other solids. Examples: – A container of mulch or coconut fibre with worms. The worm castings (waste) can be removed for the garden. – A container of sand.

Grease Trap:

The oil and geese will raise to the surface of the water as it settles, so that it can be removed from the water. – 📺 How to make the easiest home-made grease trap by Off Gridding on a Shoestring – 📺 How a Grease Trap Works by Southwaste Disposal LLC

Mock Wetlands:

wetland plants grown in a gravol rock medium (such as volcanic rock). The plants and microorganisms will help break down food particles and minor pollutants into harmless elements. Some wetland plants are even known to remove heavy metals. – 📺 How to Recycle Waste Water Using Plants by Andrew Millison

Holding tank.

A tank to hold the now filtered water.

Toilet System:

Some companies (such as Aqualoop are selling systems that clean your water in a reservoir within your house, so that the grey water can be used within toilets. There is little point to use potable (drinkable) water within your toilet, so these systems can save money and water.
