In the last decades, the hydrology and water management sectors have been dealing with global changes, proposing several innovative solutions. Climate changes are leading to an increase of long hot and dry periods, alternated by short and intense rainfall events. Urban areas are particularly vulnerable to these changes: rapid population growth and intense anthropic activity enhance the risk of extreme hydrological events. Several solutions have been proposed in the last years to monitor, prevent, forecast and mitigate rainfall extremes and their effects in natural and urban environments. Some questions, however, remain unsolved and new issues are challenging the hydrological community. The inter- and multidisciplinary aims and topics discussed in the chapters of this book are organised into the following three main topics: (1) Climate change and geo-hydrological risk, (2) Tools and techniques for improving the comprehension of catchment hydrology and river hydraulics, and (3) Sustainable use of water resources. In Focus - a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

The goal of this book is to improve understanding of the role wetlands perform in processing nutrients and contaminants, and to discuss and demonstrate how restored and constructed wetlands in the future, via their associated ecosystem services, can contribute to ensure sustainable water management and resource recovery while at the same time regulating and mitigating impacts of global climate change. Topics covered include: - various treatment wetland types, e.g. free water surface wetlands, subsurface flow wetlands, and intensified wetlands - the performance of treatment wetlands for different types of water, e.g. greywater, industrial wastewater, and agricultural runoff - the performance of treatment wetlands for removing selected micro-pollutants - the impact of salinity on the treatment performance.

Nowadays, hydrological systems are becoming increasingly complex owing to the growing interaction between nature and humans at the local scale of river sections, lakes, reservoirs, catchments, etc., to the global scale. There is great demand for the development of models to evaluate, predict, and optimize the performance of complex hydrological systems whose behavior is characterized by a strong nonlinearity. However, traditional approaches can hardly handle this nonlinear behavior; moreover, the analysis of hydrological systems at the large scale, even global, requires dealing with large-volume and real-time data. In recent years, artificial intelligence (AI), especially deep learning, has shown great potential to process massive data and solve large-scale nonlinear problems. AI has been successfully applied to computer vision, machine translation, bioinformatics, drug design, and climate science. AI models have produced results comparable to and even better than expert human performance. It is expected that AI can significantly contribute to hydrology research as well as development. This book presents some of the latest advances in the field of AI in hydrology. Both theoretical and experimental chapters are included, covering new and emerging AI methods and models from various challenging problems in hydrology.

The main challenge in wastewater treatment is changing the perception of wastewater as a waste product to be treated or disposed of, and instead seeing it as a source of energy and other valuable byproducts. This approach is in line with the basic principles of a circular economy, which replaces the 'end-of-life' concept with reducing, reusing, recycling, and recovering materials in production, distribution and consumption processes. The anaerobic treatment of wastewater aligns with these goals: energy, safe water and nutrients can all be recovered in the process. As a result, the anaerobic process could represent the best mainstream treatment option for domestic wastewater. The development of powerful technologies such as high-rate and membrane reactors is making anaerobic wastewater treatment more viable, especially in cold and moderate climate regions where the process is made more challenging due to the low process efficiency for dilute streams such as domestic wastewaters. Anaerobic Treatment of Domestic Wastewater: Present Status and Potentialities presents the current state of knowledge and future perspectives of the anaerobic process applied as a mainstream treatment method of domestic wastewater. 12 chapters cover engineering, microbiology, process monitoring and control, sustainability, life-cycle assessment, and techno-economic analysis. Topical areas of research, including the fate of microplastics and antibiotic resistance in the treatment line, are also discussed. This book provides all the necessary knowledge to analyse, evaluate, design, and implement anaerobic bioreactors for domestic wastewater treatment, making it essential reading for doctoral and master's students of water treatment subjects, and professionals or researchers in the water sector.

The COVID-19 pandemic demonstrated the necessity for highly interdisciplinary, multi-stakeholder collaboration to enable effective public health practice and response. The application of wastewater monitoring to support the pandemic response was demonstrated quickly, leveraging existing scientific and engineering capability to develop rapidly methods that enabled scaling of monitoring programmes across the globe. The science and practice of wastewater monitoring, or wastewater-based epidemiology (WBE) as it is often termed in the context of surveillance, for public health threats is well-documented. As a highly socialised tool, national, regional and international communities of interest have joined efforts to provide evidence of the value of the data derived and its application in practice. While the use of wastewater monitoring to detect and characterise targets of public health concern is not new, COVID-19 and the (re)emergence of rare, novel or unexpected pathogens stresses the importance of continued research and development into the utility of wastewater monitoring and utility of the data it generates. As wastewater monitoring continues to move from the research community into applied public health agencies, there is a need to develop standard methods and data analytics for specific applications. Establishing WBE at the frontier of global public health requires a clearer understanding and acknowledgment of its value by public health policy makers, regulators and government. This book presents a broad view of WBE thinking and practice, delineating the current understanding and future potential of the field. The topics covered range from geographically distinct reports on the use of WBE to inform on pathogen circulation in a population, through technical developments and data utility, to commentaries on future challenges and opportunities including for WBE 'beyond the pandemic'.

The first edition of this book was published in 2008 and it went on to become IWA Publishing's bestseller. Clearly there was a need for it because over the twenty years prior to 2008, the knowledge and understanding of wastewater treatment had advanced extensively and moved away from empirically-based approaches to a fundamental first-principles approach based on chemistry, microbiology, physical and bioprocess engineering, mathematics and modelling. However the quantity, complexity and diversity of these new developments was overwhelming for young water professionals, particularly in developing countries without readily available access to advanced-level tertiary education courses in wastewater treatment. For a whole new generation of young scientists and engineers entering the wastewater treatment profession, this book assembled and integrated the postgraduate course material of a dozen or so professors from research groups around the world who have made significant contributions to the advances in wastewater treatment. This material had matured to the degree that it had been codified into mathematical models for simulation with computers. The first edition of the book offered, that upon completion of an in-depth study of its contents, the modern approach of modelling and simulation in wastewater treatment plant design and operation could be embraced with deeper insight, advanced knowledge and greater confidence, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks, or biofilm systems. However, the advances and developments in wastewater treatment have accelerated over the past 12 years since publication of the first edition. While all the chapters of the first edition have been updated to accommodate these advances and developments, some, such as granular sludge, membrane bioreactors, sulphur conversion-based bioprocesses and biofilm reactors which were new in 2008, have matured into new industry approaches and are also now included in this second edition. The target readership of this second edition remains the young water professionals, who will still be active in the field of protecting our precious water resources long after the aging professors who are leading some of these advances have retired. The authors, all still active in the field, are aware that cleaning dirty water has become more complex but that it is even more urgent now than 12 years ago, and offer this second edition to help the young water professionals engage with the scientific and bioprocess engineering principles of wastewater treatment science and technology with deeper insight, advanced knowledge and greater confidence built on stronger competence.

Intermittent Water Supply is common in the majority of countries in South Asia, Latin America, Africa and the Middle East. There are different factors that cause intermittency in water systems such as natural, technical and financial scarcity as well as user behaviour and institutional aspects. Intermittent access to water can have consequences on public health and social equity. Intermittent Water Supply systems are considered as failing systems that are not sustainable in the long-term. A lot of work has been done by researchers and practitioners to better understand these systems, to improve their operation and management, and eventually their conversion to continuous water supply systems. This book addresses the challenges, opportunities and solutions of IWS systems. Authors highlight the importance of these topics and provide innovative solutions to the challenges facing IWS systems. The book is an important contribution to the ongoing efforts to address the challenges of IWS systems and the chapters within it provide valuable insights for researchers and practitioners.

The contribution of this book lies in the historical comparison of infrastructural systems that normally are dealt with separately. The synthesis has been achieved mainly by an extensive literature review of research from a wide range of various fields and by using prime sources to some extent. The comparative and long-term perspective allows similarities and differences to be discovered in the development of arrangements around streets, water, and sanitation. By using the analytical lens of publicness, the author challenges the common belief that these three areas have always been public concerns or obligations. An assumption that relies on the fact that presently they indeed are public infrastructural systems. Furthermore, it is shown that the evolution of municipal streets, water, and sanitation has left a historical legacy which is still affecting the way these infrastructural systems are managed today.

Spanish translation of Nature Based Solutions for Wastewater Treatment. There are 2.4 billion people without improved sanitation and another 2.1 billion with inadequate sanitation (i.e. wastewater drains directly into surface waters), and despite improvements over the past decades, the unsafe management of fecal waste and wastewater continues to present a major risk to public health and the environment (UN, 2016). There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS such as treatment wetlands. There is increasing scientific evidence that treatment systems with designs inspired by nature are highly efficient treatment technologies. The cost-effective design and implementation of ecosystems in wastewater treatment is something that exists and has the potential to be further promoted globally as both a sustainable and practical solution. This book serves as a compilation of technical references, case examples and guidance for applying nature-based solutions for treatment of domestic wastewater, and enables a wide variety of stakeholders to understand the design parameters, removal efficiencies, costs, co-benefits for both people and nature and trade-offs for consideration in their local context. Examples through case studies are from across the globe and provide practical insights into the variety of potentially applicable solutions.

This Scientific Technical Report demonstrates meta-data strategies for water resource recovery facilities (WRRF), including the essential data validation with machine learning and traditional methods. The report is the result of extensive work from many water data experts and a utility focus group, with the dedicated application of WRRF data. Emerging trends in artificial intelligence and machine learning project unforeseen possibilities in managing our WRRF's. Hope is built upon the large data volumes collected with high frequency from both existing sensors, as well as new uncoordinated data sources outside the fence. The data variety however makes it challenging to reuse data, especially when the purpose changes. Without a proper data description (meta-data), modelling and autonomous digitalization will be difficult, and likely remain a vision. Likewise, quantified data quality are key meta-data to decide when data are fit-for-purpose. The report aims to fill the gap of how meta-data can be used in practice to leverage the value of data in a WRRF context. The report describes existing methods and systematic methodologies to collect and reconcile meta-data describing signal generation, signal quality, and contextual meta-data. The sometimes ambiguous data terminology is clarified with real WRRF examples to endorse adoption in practice. Guidelines for data quality assessment is a central part and cover both standard sensor validation protocols, as well as a separate chapter on data analytical techniques. The latter serves as a smorgasbord with mechanistic and data-driven algorithms for online sensor quality assessment. The report is intended as a reference guide for the practitioner who aims at future proofing, but also maximizing, the current use of today's recorded WRRF data. The content bridges theory with current practices and provides a base tool for the WRRF data practitioner.
