Water and Sustainable Design

Greywater comes from baths, sinks and showers and can be recycled and reused for watering the garden or flushing toilets. Reusing greywater for flushing toilets can save up to 50% of domestic water use, but requires some form of treatment such as filtering and disinfectant to remove bacteria and other biological material. If used directly for watering the garden, greywater can be left untreated, but only biodegradable, non-toxic household cleaning and toiletry products should be used in the water system. Other fats and additives might need to be treated for garden use, and the soil should be tested regularly for nutrient and chemical composition. Greywater systems range from advanced commercial designs to DIY self-built models.
