Abstract/Summary

Separating greywater before it combines with sewage and laundry effluents can be used to sustain urban environments and their green infrastructure by irrigating using treated greywater. An analytical approach to the quality and reuse opportunities for greywater leads to the determination of water reuse and irrigation potential, feasibility, and water stewardship. The evidence from various studies shows that lightly loaded greywaters can probably be used with confidence for watering certain types of green infrastructure. This is an important potential means for sustaining vegetation during times of water stress or drought. For larger volume discharges, affordable system configurations for achieving licensable discharges to support plants need to be identified and approved. For smaller, domestic-scale discharges, it appears that there is often little legislative barrier to direct irrigation using treated greywater. Rationalisation of the technology configuration, and thus the potential costs to be incurred, will provide an opportunity to carefully design and implement landscaping specifically to work in conjunction with irrigation systems. This will reduce levels of pollutants entering the urban environment while establishing and developing the opportunity for more greywater sources to be utilised in a sustainable manner.
