The recent drought in South Eastern Australia and associated water restrictions led to
a significant increase in the use of greywater for the watering of lawn and garden
areas. There was also an emerging trend for sustainable drought resistant landscaping
for which some Australian native plants were suitable. There however was an
uncertainty about whether greywater was a useful source of water for plants or
whether it could be harmful. This study investigated how two varieties of turf Kikuyu (Pennisetum Clandestinum)
and Tall Fescue (Festuca arundinacea), and two varieties of Australian native flowers
Scaly Buttons (Leptorhynchos squamatus) and Small Vanilla Lilies (Arthropodium
minus) grew when watered with several different types of greywaters sourced from a
bathroom shower and a laundry.
