What is greywater?

Water used in homes has long been thought of in terms of clean drinking water (known as potable water) coming into the house from the mains and sewage going out. However, the wastewater from baths, showers, washing machines, dishwashers and sinks fits somewhere in-between and this is referred to as greywater, which typically makes up between 50-80% of a household’s waste water.

Roughly a third of the water used in households is used in toilets, which comes into contact with human waste and is known as blackwater. If recycled properly, greywater can save approximately 70 liters of potable water per person per day in domestic households, therefore greywater recycling is one of a number of water solutions that we should look to in order to decrease our usage as the reclaimed greywater can be used to flushing toilets, wash clothes and water your garden.

If your house is metered, recycling greywater can significantly reduce the volume of water you use thereby saving you money on your water bills.

There are various ways to treat greywater, ranging from very simple methods to complex fully automated treatment systems, depending on what you want to use the water for. To find out more please visit the link below.
