What is Grey Water?
Grey water, is generally accepted as being waste water generated from wash hand basins, showers and baths, which can be recycled on-site for uses such as toilet flushing, landscape irrigation and constructed wetlands. Grey water often excludes discharge from laundry and dishwashers due to the high nutrient levels. It differs from the discharge of toilets which is designated sewage or blackwater to indicate it contains human waste.
Reasons why Grey Water should go back on the land and not to our water ways.
- Extreme weather conditions. Droughts are longer and more often so why not use grey water for feeding garden plants, in doing so the average household can save up to 50,000L of drinking water a year.
- It reduces the amount of freshwater needed to supply a household, and reduces the amount of waste water entering sewer or septic systems.
- “Fresh water is the life blood of nature, the subordination of water for human purposes comes at the health of those natural systems that support humans in other ways (clean our air, moderate our environment, provide us with food). So we need to nourish, share and learn to value this lifeblood. The consequences of doing otherwise can be seen in the spreading desserts across the world and the drought and famine that can soon follow.” Ecocouncil
