This manual comprises a holistic view of urban runoff quality management. For the beginner, who has little previous exposure to urban runoff quality management, the manual covers the entire subject area from sources and effects of pollutants in urban runoff through the development of management plans and the design of controls. For the municipal stormwater management agency, guidance is given for developing a water quality management plan that takes into account receiving water use objectives, local climatology, regulation, financing and cost, and procedures for comparing various types of controls for suitability and cost effectiveness in a particular area. This guidance will also assist owners of large-scale urban development projects in cost-effectively and aesthetically integrating water quality control to the drainage plan. The manual is also directed to designers who desire a self-contained unit that discusses the design of specific quality controls for urban runoff.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Wetland Systems to Control Urban Runoff integrates natural and constructed wetlands, and sustainable drainage techniques into traditional water and wastewater systems used to treat surface runoff and associated diffuse pollution. The first part of the text introduces the fundamentals of water quality management, and water and wastewater treatment. The remaining focus of the text is on reviewing treatment technologies, disinfection issues, sludge treatment and disposal options, and current case studies related to constructed wetlands applied for runoff and diffuse pollution treatment. Professionals and students will be interested in the detailed design, operation, management, process control and water quality monitoring and applied modeling issues.* Contains a comprehensive collection of timely, novel and innovative research case studies in the area of wetland systems applied for the treatment of urban runoff * Demonstrates to practitioners how natural and constructed wetland systems can be integrated into traditional wastewater systems, which are predominantly applied for the treatment of surface runoff and diffuse pollution * Assesses the design, operation, management and water treatment performance of sustainable urban drainage systems including constructed wetlands

Prepared byØtheØTask Committee of the Urban Water Resources Research Council of ASCE. Copublished by ASCE and the Water Environment Federation. Design and Construction of Urban Stormwater Management Systems presents a comprehensive examination of the issues involved in engineering urban stormwater systems. This Manual?which updates relevant portions of Design and Construction of Sanitary and Storm Sewers, MOP 37?reflects the many changes taking place in the field, such as the use of microcomputers and the need to control the quality of runoff as well as the quantity. Chapters are prepared by authors with experience and expertise in the particular subject area. The Manual aids the practicing engineer by presenting a brief summary of currently accepted procedures relating to the following areas: financial services; regulations;Ø surveys and investigations;Ø design concepts and master planning;Ø hydrology and water quality;Ø storm drainage hydraulics; andØ computer modeling.

A study of urban stormwater runoff that explores the relationships among nature, technology, and society in cities. When rain falls on the city, it creates urban runoff that cause flooding, erosion, and water pollution. Municipal engineers manage a complex network of technical and natural systems to treat and remove these temporary water flows from cities as quickly as possible. Urban runoff is frequently discussed in terms of technical expertise and environmental management, but it encompasses a multitude of such nontechnical issues as land use, quality of life, governance, aesthetics, and community identity, and is central to the larger debates on creating more sustainable and livable cities. In this book, Andrew Karvonen uses urban runoff as a lens to view the relationships among nature, technology, and society. Offering theoretical insights from urban environmental history, human geography, landscape and ecological planning, and science and technology studies as well as empirical evidence from case studies, Karvonen proposes a new relational politics of urban nature. After describing the evolution of urban runoff practices, Karvonen analyzes the urban runoff activities in Austin and Seattle—two cities known for their highly contested public debates over runoff issues and exemplary storm water management practices. The Austin case study highlights the tensions among urban development, property rights, land use planning, and citizen activism; the Seattle case study explores the city's long-standing reputation for being in harmony with nature. Drawing on these accounts, Karvonen suggests a new relational politics of urban nature that is situated, inclusive, and action-oriented to address the tensions among nature, technology, and society.
