Abstract

The concept of a greywater-fed bioretention system in arid regions was investigated in this study. Bioretention systems are conventionally used as a source control mechanism for urban runoff. Nevertheless, in arid regions, where rain and urban runoff are not an abundant water resource, their application is limited. Greywater (residential wastewater without toilet and kitchen sources) is comparatively less polluted and has the potential for reuse in irrigation and non-potable water uses. However, selection of an appropriate treatment is a challenge. A prototype bioretention system was made and its ability to improve greywater quality was monitored for more than 10 consecutive days. A vegetative and non-vegetative system were monitored separately. After 24 hours of retention in both systems, greywater quality was improved significantly. Both systems performed almost equally well; however, the vegetative system (with canary reed grass, Phalaris arundinacea) was found to be more effective in reducing the sodium and chemical oxygen demand contents. The study revealed that the concept of the greywater-fed bioretention system has the potential to add multi-functional benefits (greywater treatment, water conservation, landscape aesthetic and biodiversity) to the arid regions’ urban environment.
