Greywater is wastewater from showers, baths, washbasins, washing machines and kitchen sinks. It is possible to collect such water and, after treatment, use it for purposes that do not require drinking water quality, such as toilet flushing and garden watering. (Environmental Agency, 2011). This greatly reduces the demand on mains water as well as reducing the volume of water discharged into sewage systems.
As well as conserving water this will also save users money on their water bills (if they have water metres installed). According to the Environmental Agency (2011), greywater recycling systems have the potential to reduce the amount of mains water used in the home by about a third.
The limitations of initiatives such as rainwater harvesting and greywater harvesting are that even though it reduces demand for mains water, it does not actually contribute to a reduction in water consumption. In addition, long payback times combined with small storage volumes mean it can be less effective than other water conservation measures.
