Increasing water scarcity is encouraging the use of unconventional water resources. In recent years, the European Union has launched numerous initiatives to promote and facilitate water reuse for agricultural irrigation. Today, the use of reclaimed water for agriculture has become an alternative, reliable and safe source of water supply and an indispensable water planning tool, especially in the area of southern Europe. However, water reuse for irrigation is currently far below its potential. Numerous barriers prevent its development and call for a detailed analysis of the different aspects affecting reclaimed water reuse, through an integrated and multidisciplinary approach. A multidisciplinary research team from Universidad Politécnica de Madrid, consisting of agronomists, hydrologists, chemists and agricultural economists, will work on the RECLAMO Project (https://blogs.upm.es/reclamo/), with the aim of providing solutions and recommendations aimed at promoting the full development and use of reclaimed water for irrigation in areas of Spain with marked water stress. For this purpose, project activities will be developed in two selected case studies (the Segura Basin, leader in water reuse in Spain and the Guadiana Basin, with success stories, but low levels of water reuse) and organised according to five axes: 1) development of a comprehensive knowledge-base covering the regulatory, technical, socio-economic and environmental aspects of reclaimed water reuse in agriculture; 2) participatory development of future scenarios exploring possible strategies, barriers and opportunities, in relation to the expansion of the use of reclaimed water for irrigation; 3) impact analysis of the strategies identified at different scales (crop, farm, (sub-)basin), through the development of an integrated modelling platform (hydrologic-agronomic-economic models); 4) Development of a roadmap and policy recommendations to achieve the full development and use of reclaimed water reuse for irrigation; 5) Dissemination of knowledge and promotion of science-policy-society dialogue. To this end, RECLAMO will collaborate closely with experts and stakeholder groups that will play a key role in the project in co-creating the scenarios and modelling tools and validating the results. The project will also seek for synergies and complementarities with other similar projects and explore new ways of collaborating with companies and research groups that allow research to continue and expand beyond the spatial and temporal limits of the project. RECLAMO’s results will promote an integrated approach to the sustainable management of water resources in water-stressed areas, including reclaimed water management. The integrated modelling platform developed in the project will allow policy-makers and water users to benefit from an improved understanding of the interactions between the social, economic and environmental aspects of water systems, in the context of climate and socio-economic change that will lead to better informed decision-making to address future water challenges. In addition, RECLAMO is expected to contribute to raising awareness about the use of reclaimed water reuse in agriculture as a safe and sustainable practice and to improve its social acceptance by producing science-based knowledge that provide evidence on the benefits derived from its use.

Resumo: A escassez da água em regiões áridas e semiáridas tem sido tema de debates, políticas e pesquisas com o objetivo principal de subsidiar as ações capazes de permitir o seu aproveitamento racional, permitindo a convivência da população com os períodos de seca ou reduzida precipitação. Assim, a escassez de água tem conduzido à implantação de projetos de desenvolvimento, que têm como desafio a busca de alternativas de convivência com a seca que conduzam a melhorias sociais. Com base nesse contexto, este estudo tem como objetivo propor a criação de um modelo de construção de cenários para viabilidade do reúso de água para ser utilizado como elemento mitigador das implicações da seca em regiões semiáridas. O modelo de construção de cenários é um importante instrumento de gerenciamento de recursos naturais, neste caso específico, recursos hídricos, pois permite envolver um grande número de participantes, tem a possibilidade de orientar o debate público para a construção estratégica coletiva de um futuro almejado, contribui para um eficaz processo de aprendizagem organizacional no âmbito do Sistema Nacional de Gerenciamento de Recursos Hídricos visando um melhor entendimento, tanto dos aspectos ambientais quanto dos aspectos sociais e institucionais relacionados aos recursos hídricos no País, em especial, nas regiões semiáridas. Como se trabalham e convivem com a incerteza, os cenários procuram analisar e sistematizar as diversas probabilidades dos eventos e dos processos por meio da exploração dos pontos de mudança e das grandes tendências, de modo que as alternativas mais prováveis sejam antecipadas.Palavras-chaves: Recursos Hídricos.

Construção de Cenários.Abstract: Water scarcity in arid and semi-arid regions has been the subject of debates, policies and research with the main objective of subsidizing actions capable of allowing their rational use, allowing the population to coexist with periods of drought or reduced precipitation. Thus, water scarcity has led to the implementation of development projects, which challenge the search for alternatives to coexistence with drought that lead to social improvements. Based on this context, this study aims to propose the creation of a model for the construction of scenarios for the feasibility of water reuse to be used as a mitigating element of the drought implications in semi-arid regions. The scenario building model is an important tool for managing natural resources, in this specific case, water resources, since it allows a large number of participants to be involved, it has the possibility of guiding the public debate towards the collective strategic construction of a desired future, contributes to an effective organizational learning process within the National Water Resources Management System aiming at a better understanding of both the environmental aspects and the social and institutional aspects related to the water resources in the Country, especially in the semi-arid regions. As they work and coexist with uncertainty, the scenarios seek to analyze and systematize the various probabilities of events and processes by exploring the points of change and the major trends, so that the most likely alternatives are anticipated.Keywords: Water Resources.

Global fresh water resources are under increasing pressure from rapidly growing demands and changing climatic conditions. Wastewater reclamation is becoming an important alternative for sustainable water resources management and building climate change resiliency in many regions around the world. Public acceptance and trust of consumers in the quality of reclaimed water is considered by many to be the most important factor determining the outcomes of water reclamation projects. Knowledge of the urban water cycle and water reuse perceptions of student, faculty and staff at Western University were investigated. Results showed that members of the university community are more likely to accept reclaimed wastewater for applications that do not involve drinking or close personal contact. Knowledge of the urban water cycle and water resources in Canada is modest among the university community with a moderate (G = 0.303, p < 0.05) positive relationship between ‘water knowledge’ and ‘close contact acceptability’. The majority of the university community (75.8%) thinks that reclaiming water to provide an alternate source of water in southwestern Ontario is a good idea, but there are still concerns about the presence of chemicals such as pharmaceuticals from reclaimed water and the long-term effects on human health from exposure to these contaminants.

Abstract This article offers an evaluation of the reuse of reclaimed water and desalination in Spain and aims to provide an overview of the state of the art and Spanish legal framework as far as non-conventional resources are concerned. The fight against the scarcity of water resources in this country, especially in the southeast, has made the production of new alternative water resources a clear priority and has turned the nation into a leader in water reuse and seawater desalination. The assessment presented can be used to help build a more general framework, like the European one, and shed light on other comparative legal experiences.

Essential Components

Water reclamation and reuse have become essential components of water resources management in the Metropolitan Area of Barcelona, by helping to develop additional water resources in the lower Llobregat River, one of its main sources of water supply. By generating a reliable flow of 300,000 m3/day of high quality reclaimed water, the options available for integrated water resources management have widely expanded to allow in-stream river water substitution, restoration of natural wetland areas, agricultural irrigation, and supply to a seawater intrusion barrier. Those management options have been possible thanks to the implementation of an extensive water distribution system that allows distribution of reclaimed water to a point 15 km upstream of the reclamation facility, and to a seawater intrusion barrier within a few kilometres of the plant. The cost of producing reclaimed water using a physico-chemical process (0.05 €/m3) and the investment required for such a facility (0.21 €/m3 annual capacity) are very close to those of similar large scale projects in Spain. However, higher degrees of treatment, such as demineralization for agricultural irrigation and for injection into a seawater intrusion barrier, result in considerable increases of both water reclamation cost and investment costs.

Water reclamation and reuse provides a unique and viable opportunity to augment traditional water supplies. As a multi-disciplined and important element of water resources development and management, water reuse can help to close the loop between water supply and wastewater disposal. Effective water reuse requires integration of water and reclaimed water supply functions. The successful development of this dependable water resource depends upon close examination and synthesis of elements from infrastructure and facilities planning, wastewater treatment plant siting, treatment process reliability, economic and financial analyses, and water utility management. In this paper, fundamental concepts of water reuse are discussed including definitions, historical developments, the role of water recycling in the hydrologic cycle, categories of water reuse, water quality criteria and regulatory requirements, and technological innovations for the safe use of reclaimed water. The paper emphasizes the integration of this alternative water supply into water resources planning, and the emergence of modern water reclamation and reuse practices from wastewater to reclaimed water to repurified water.
