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. Greywater is much easier to treat and recycle when compared with blackwater because there is no faecal matter that is a haven for harmful bacteria and disease causing pathogens. If recycled properly, greywater can save approximately 70 litres 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. Greywater is never going to be safe to drink, even when treated. However the reclaimed greywater can be used to flushing toilets, wash clothes and water your garden.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.
