As water consumption demands have increased together with shortage in rainfall during
last few years, the crisis in water supply become apparent in many regions across
Australia, including Toowoomba. More efficient use of other resources as valuable as
water should therefore be encouraged. One feasible resource is greywater, which has
been reused widely for toilet flushing and garden watering in many nations around the
worlds such as Japan, USA, Singapore and Hong Kong. The reuse of greywater in
individual households in Australia can contribute towards the reduction in water
consumption and wastewater volume discharged into treatment systems. Laundry water
is one of components in greywater which is considered to be less polluted than many
other wastewaters. In addition, laundry water usually contains many essential nutrients
for plant growth. Therefore, laundry water may be reused for garden irrigation without
treatment. If feasible, this practice would provide a cost-effective solution to conserve
water and improve soil nutrients. This paper focused on determining the quantity and
quality of laundry water generated from a Toowoomba household. The results would be
used to evaluating the reuse potential of laundry water for lawn and garden irrigation
without treatment. The impacts of laundry water application on human health and soil
properties were also taken into account in this paper.
