“…Researchers still need to better understand how the public reacts to reclaimed water. According to some previous studies [17,18], existing information gaps make it difficult to fully comprehend the particular circumstances in which the society is responsive to alternate water sources and the patterns in which public acceptability can vary across locations. The determinants of water reuse acceptability are strongly interconnected and highly complex.…”

To address water scarcity, treated wastewater has been demonstrated to be a more practical and environmentally beneficial solution than untreated wastewater. Nowadays, it is well acknowledged that social marketing and advocacy are inefficient at getting people to use recycled water. It is widely understood that the key components of any reuse project's success are public attitudes and acceptance of water reuse. This paper aims to present a summary of the literature on water reuse, with a focus on issues that may influence how the public perceives water reuse. In this study, a variety of social, psychological, and demographic variables are linked to higher levels of public support for wastewater use. The level of knowledge in this field is included in the conclusion, along with advanced suggestions and policy implications for improving our understanding of the socio-psychological and technological forces behind water reuse for multiple applications.

“…Indirect potable reuse represents less than 2% of the market share of the global planned water reuse market [5]. This trend is likely to continue due to the high cost of infrastructure investments, technology costs, and the low public acceptance to use recycled wastewater as a source of drinking water [6]. Standardized viral monitoring methods to assess treatment performance and risks of water reuse are critically needed for use in anticipated diverse non-potable reuse scenarios.…”

Wastewater reclamation and reuse have the potential to supplement water supplies, offering resiliency in times of drought and helping to meet increased water demands associated with population growth. Non-potable water reuse represents the largest potential reuse market. Yet, economic constraints for new water reuse infrastructure and safety concerns due to microbial water quality, especially viral pathogen exposure, limit the widespread implementation of water reuse. Cost-effective, real-time methods to measure or indicate the viral quality of recycled water would do much to instill greater confidence in the practice. This manuscript discusses advancements in monitoring and modeling viral health risks in the context of water reuse. First, we describe current wastewater reclamation processes and treatment technologies with an emphasis on virus removal. Second, we review technologies for the measurement of viruses, both culture- and molecular-based, along with their advantages and disadvantages. We outline promising viral surrogates and specific pathogenic viruses that can serve as indicators of viral risk for water reuse. We suggest metagenomic analyses for viral screening and flow cytometry for quantification of virus-like particles as new approaches to complement more traditional methods. Third, we describe modeling to assess health risks through quantitative microbial risk assessments (QMRAs), the most common strategy to couple data on virus concentrations with human exposure scenarios. We then explore the potential of artificial neural networks (ANNs) to incorporate suites of data from wastewater treatment processes, water quality parameters, and viral surrogates. We recommend ANNs as a means to utilize existing water quality data, alongside new complementary measures of viral quality, to achieve cost-effective strategies to assess risks associated with infectious human viruses in recycled water. Given the review, we conclude that technologies will be ready to identify and implement viral surrogates for health risk reduction in the next decade. Incorporating modeling with monitoring data would likely result in a more robust assessment of water reuse risk.

“…While the required technology to maintain water safety is readily available, public acceptance is the basic premise for the implementation of stormwater reuse projects anywhere in the world [ 17 ]. The social science study on public acceptance for using non-conventional waters, including recycled wastewater and recycled stormwater, originated early in this century.…”

Public acceptance is the basic premise for the implementation of stormwater reuse projects anywhere in the world. Based on the theory of planned behaviour, this study constructed a hypothesized model of urban residents’ intention to use recycled stormwater for non-potable residential purposes. Having received 669 valid questionnaires from urban residents in Taiyuan City, a Structural Equation Model was used to analyze their acceptance intention to use recycled stormwater. Results of the study showed that the degree of human contact with recycled stormwater influenced respondents’ acceptance intention to use it for that purpose, which is consistent with previous studies. The impact of factors, including valuation of stormwater, emotions, perceived health risks, or trust in government, on respondents’ acceptance intention to use recycled stormwater was found to be not significant, which adds to the inconsistent literature. The unique contributions of the study to literature include that altruism and social and cultural norms were found to have significantly positive impacts on residents’ acceptance intention to use the water, while social and cultural norms demonstrated a more significant impact. This finding is perceived to relate to the collectivism of Chinese culture; however, to what extent the relation could be requires further research to verify. The study also makes contributions to methodology by using social networking (WeChat Moments) to collect data in social science studies.
