“…Some communities are cautious about greywater reuse for irrigation due to the limited information or awareness programs on the potential of greywater reuse as a clean supplement for fresh water [8]. A recent socio-economic study on greywater reuse shows that there is an overall acceptance for using high-quality treated greywater for toilet flushing, laundry, garden irrigation, but not for drinking [51]. In addition, the previous knowledge about greywater reuse, educational level, gender, and age are critical determinants of acceptability [51].…”

An Assessment of Treated Greywater Reuse in Irrigation on Growth and Protein Content of Prosopis and Albizia

This study investigated the influence of treated greywater on growth and protein content of multipurpose (forage and ornamental) transplants, Prosopis juliflora L., Prosopis tamarugo L., and Albizia lebbeck L. Transplants of tested species were irrigated with treated greywater, diluted greywater (grey + distilled water, 1:1/by volume), and distilled water (control) for seven months. Water quality analysis showed that the concentrations of nutrients and heavy metals found in the greywater were within the acceptable range compared with Jordan Institution for Standard and Metrology (JISM) and the World Health Organization (WHO) thresholds for safe use of greywater. Escherichia coli found in the greywater were lower compared to JISM and WHO guidelines for the safe use of greywater. Irrigation with treated greywater increased shoot fresh weight by 24–39% and dry weight by 34–40% compared to diluted greywater and control. No significant difference in crude protein was noticed between water treatments. Prosopis species (P. juliflora Albizia lebbeck L. and P. tamarugo Albizia lebbeck L.) had higher shoot fresh (35%) and dry weight the same species had lower crude protein (44%) when compared to Albizia lebbeck Albizia lebbeck L. The reuse of treated greywater for landscaping or forage production alleviates the demand for water resources and reduces the pressure on wastewater treatment plants. However, considering the controversial findings of previous studies on greywater quality (especially, long-term reuse), the reuse of treated greywater needs to be considered with caution and periodic quality analyses and economic assessments are required.

“…Na Alemanha, o reuso da AC é usado na recarga de água subterrânea, paisagismo e irrigação (Al-Jayyousi, 2003). No Chile há uma aceitação geral para o uso de água cinza tratada de alta qualidade para descarga de vasos sanitários, lavanderia, irrigação de jardins, lavagem das mãos e uso do chuveiro / banheira (seguindo uma ordem decrescente de prioridade) (Amaris et al, 2020). Em geral a água cinza é um recurso hídrico potencialmente reutilizável para irrigação de gramados e jardins domésticos (Al-Jayyousi, 2003), visto que o desvio de efluentes da lavanderia para jardins e gramados é tecnicamente possível sem tratamento (Jeppesen, 1996).…”

“…Greywater is defined as relatively clean waste water from baths, sinks, and washing machines (Amaris et al, 2020). According to Amaris, Dawson, Gironás, Hess & Ortúzar in 2020, grey water reuse has been emerging in recent years as a viable and sustainable water strategy due to a number of reasons (Amaris et al, 2020). Firstly, the volume of grey water that can be reused constitutes a significant proportion of the consumed water (Amaris et al, 2020).…”

PUBLIC ACCEPTANCE OF GREY WATER REUSE: A CASE STUDY & ANALYSIS IN THE UAE

Fresh water is considered a limited resource in the United Arab Emirates (UAE), with full reliance on ground water and desalinated saline water. Grey water reuse has been investigated as a solution to reduce the demand for potable water and to provide an alternative water resource. However, public perceptions and acceptance of treated wastewater is a significant factor for adopting grey water reuse on a wide domestic scale. This study aims to investigate the factors influencing public acceptance of grey water reuse. A stated preference survey is designed and distributed in the different Emirates of the UAE. The results of the study suggest that there is still a lack of awareness in the perception of fresh water availability among residents in the UAE. Moreover, 70 % of the surveyed sample agreed to use treated grey water in applications not involving direct contact. Factors influencing public acceptance were found to be health risk concerns, lack of confidence in the water quality, lack of scientific knowledge about the treatment process and the potential uses of treated grey water.
