Grey water is the wastewater produced from the hand basin, shower, bath, washing machine and laundry tub. It is not the water from the toilet, kitchen sink or dishwasher as this water is generally too high in grease and oil to be re-used successfully.
Grey water irrigation has long been practiced in areas with a limited water supply. However, proper precautions for its use have not always been in place. This posed a problem for health officials, who believed that there was no correct method for managing grey water to both balance user water needs with public safety considerations.
Netafim grey water systems can now meet both environmental and waste management requirements, while safely utilising the nutrient content in the effluent.
