Recycled drinking water represents one of the most obvious and technologically reliable sources of urban water. Yet it is one of the least implemented solutions. Blame has often been laid on the emotional and psychological difficulties of persuading people that recycled drinking water is safe to drink. This ‘yuck’ factor has been empirically identified as a statistically significant variable. But how are such factors perceived? And more importantly – can these perceptions be changed? This study attempts a quantitative study of public perceptions and norm formation in recycled drinking water. Using the Q methodology, which reveals the subjective perceptions of key stakeholders, we uncover the following discourses: (1) technology can change current paradigms; (2) ensuring a safe water supply is a problem that has an economic cost; (3) environmental and global realities make it imperative to recycle water. These findings confound two prevailing views – that the debate in recycled drinking water is one of science over emotions, and more information can ‘overcome’ the apparently irrational norm formation. Instead, we find no new information in this case. Rather what was present was a new interpretative frame that allowed a new narrative enabling the bridging of two previously contradictory positions – in this instance, the pro- and anti-water reuse discourses.

Membrane Treatment

The present Special Issue brought together recent research findings from renowned scientists in this field and assembled contributions on advanced technologies that have been applied to the treatment of wastewater and drinking water, with an emphasis on novel membrane treatment technologies. The 12 research contributions highlight various processes and technologies that can achieve the effective treatment and purification of wastewater and drinking water, aiming (occasionally) for water reuse. The published papers can be classified into three major categories. (a) First, there are those that investigate the application of membrane treatment processes, either directly or in hybrid processes. The role of organic matter presence and fouling control is the main aim of the research in some of these studies. (b) Second, there are studies that investigate the application of adsorptive processes for the removal of contaminants from waters, such as arsenic, antimony, or chromate, with the aim of the efficient removal of the toxic contaminants from water or wastewater. (c) Lastly, there are studies that include novel aspects of oxidative treatment such as bubbleless ozonation.

A better understanding of the processes that influence public perception can contribute to improvements in water management, consumer services, acceptability of water reuse and risk communication, among other areas. This paper discusses some of the main variables involved in public perception of drinking water quality. Research on this topic suggests that perceptions of water quality result from a complex interaction of diverse factors. In many circumstances, the estimation of water quality is mostly influenced by organoleptic properties, in particular flavour. In addition, a variety of other factors also have an influence on perceptions of quality. These include risk perception, attitudes towards water chemicals, contextual cues provided by the supply system, familiarity with specific water properties, trust in suppliers, past problems attributed to water quality and information provided by the mass media and interpersonal sources. The role and relevance of these factors are discussed in detail.

As water supplies become strained, some municipalities have turned to reclaimed water as a potential source to meet non-potable needs. Such reclaimed water – wastewater effluent treated to appropriate quality standards – is not suitable for human consumption without additional treatment, but can be used for purposes such as irrigation and cooling. One reclaimed water distribution system of particular interest is at the University of Texas at Austin (UT), USA, which receives treated effluent from City of Austin wastewater treatment plants. Depending on the embedded energy of existing water sources, existing levels of wastewater treatment, and the extent of the relevant distribution network, water reuse can save energy and carbon emissions compared with conventional drinking water distribution systems, at the expense of higher capital costs. Our analysis uses EPANet modeling software and historical datasets to examine the embedded energy and carbon emissions in drinking water and reclaimed water for non-potable applications at UT. We then examine the overall economics of reclaimed water use, including capital and operating costs for a variety of amortization periods, financing costs, and externality costs using a levelized-cost of water methodology. This integrated analysis serves as the basis for developing principles of sustainable water reuse.

Drinking Water Production

To obtain a sustainable water catchment in the dune area of the Flemish west coast, the integration of treated domestic wastewater in the existing potable water production process is planned. The hygienic hazards associated with the introduction of treated domestic wastewater into the water cycle are well recognised. Therefore, the concept of HACCP (Hazard Analysis and Critical Control Points) was used to guarantee hygienically safe drinking water production. Taking into account the literature data on the removal efficiencies of the proposed advanced treatment steps with regard to enteric viruses and protozoa and after setting high quality limits based on the recent progress in quantitative risk assessment, the critical control points (CCPs) and points of attention (POAs) were identified. Based on the HACCP analysis a specific monitoring strategy was developed which focused on the control of these CCPs and POAs.

Abstract The present study highlights the evolution, the progress and the prospects of future practices of water reuse in the world. The objective was to produce a comprehensive timeline on the global evolution and progress of water reuse. This was achieved through the analysis of the state of the art on the subject. The present study is a qualitative research, where three aspects have been considered to highlight the global evolution of water reuse: i) Regulations, Standards, Criteria or Guidelines (RSCG); ii) Indirect Potable Reuse Projects (IPR); and iii) Direct Potable Reuse Projects (DPR). The study focused on both legal and practical aspects of water reuse and considered 3 timelines in the context of RSCG, IPR and DPR: 29 RSCG instruments, institutionalized from 1918 to 2020, where only 4 instruments were solely dedicated to drinking water reuse; 10 IPR projects; 5 DPR projects. To achieve good, effective results, the regulatory framework must support the objectives of a structured water reuse policy in addition to guaranteeing legitimacy and maintaining public confidence. Integrated water and wastewater management, based on technological and scientific advances, has become a relevant aspect for implementation of more adequate measures by decision makers to address future global water challenges.
