By 2025, two thirds of the world’s population will be living in water stressed conditions. Meanwhile, the degradation of water ecosystems is occurring at alarming rates. Water utilities and water regulators that choose to play an active role in catchment management with nature based solutions (NBS) are uniquely positioned to help. Building a robust knowledge base and supporting opportunities for cross-sector collaboration are fundamental to the mainstreaming of NBS. The International Water Association (IWA) and The Nature Conservancy (TNC) are working together to encourage and facilitate active utility involvement in NBS, as well as promoting stronger connections between water utilities and regulatory bodies. Implementation of NBS involves multiple, interdependent stakeholders at various governance levels, and consequently regulators a key role in creating the enabling environments for these interactions and negotiations. This publication taps into diverse geographies and contexts, delving into case studies for a richer conversation that addresses the variety of challenges and elements for success for integrating NBS into water utility operations and planning. By publicizing successful case studies, the IWA/TNC partnership fulfils a dual purpose of endorsing these efforts and providing actionable guidance for other water utilities striving to improve their sustainability and resiliency.

Provides the tools needed to control and remediate the quality of natural water systems Now in its Second Edition, this acclaimed text sets forth core concepts and principles that govern the fate and transport of contaminants in water, giving environmental and civil engineers and students a full set of tools to design systems that effectively control and remediate the quality of natural waters. Readers will find coverage of all major classes of water bodies. Moreover, the author discusses the terrestrial fate and transport of contaminants in watersheds, underscoring the link between terrestrial loadings and water pollution. Water-Quality Engineering in Natural Systems begins with an introduction exploring the sources of water pollution and the control of water pollution. It then presents the fundamentals of fate and transport, including the derivation and application of the advection–diffusion equation. Next, the text covers issues that are unique to: Rivers and streams Groundwater Watersheds Lakes and reservoirs Wetlands Oceans and estuaries The final two chapters are dedicated to analyzing water-quality measurements and modeling water quality. This Second Edition is thoroughly updated based on the latest findings, practices, and standards. In particular, readers will find new methods for calculating total maximum daily loads for river contaminants, with specific examples detailing the fate and transport of bacteria, a pressing problem throughout the world. With end-of-chapter problems and plenty of worked examples, Water-Quality Engineering in Natural Systems enables readers to not only understand what happens to contaminants in water, but also design systems to protect people from toxic pollutants.

At present, constructed wetlands for wastewater treatment are a widely used technology for treatment of various types of wastewaters. The International Water Association (then International Association on Water Pollution Research and Control) recognized wetlands as useful tools for wastewater treatment and est- lished the series of biennial conferences on the use of wetland systems for water pollution control in 1988. In about 1993, we decided to organize a workshop on nutrient cycling in natural and constructed wetlands with the major idea to bring together researchers working on constructed and also natural wetlands. It was not our intention to compete with IWA conferences, but the workshop should rather complement the series on treatment wetlands by IWA. We believed that the exchange of information obtained from natural and constructed wetlands would be beneficial for all participants. And the time showed that we were correct. The first workshop took place in 1995 at T?ebo? in South Bohemia and most of the papers dealt with constructed wetlands. Over the years we extended the topics on natural wetlands (such as role of wetlands in the landscape or wetland restoration and creation) and during the 6th workshop held at T?ebo? from May 30 to June 3, 2006, nearly half of 38 papers presented during the workshop dealt with natural wetlands. This workshop was attended by 39 participants from 19 countries from Europe, Asia, North and South Americas and Australia. The volume contains 29 peer-reviewed papers out of 38 papers which were presented during the workshop.

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.

Discusses whether wastewater treatment costs could be reduced by using alternative wastewater treatment systems. Addresses (1) whether there are cost-effective alternatives to conventional systems for collecting & treating wastewater, (2) whether barriers are limiting the use of these alternatives, & (3) how EPA is addressing the development of future technologies. Charts & tables.
