Book Description
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.

Book Description
Urban runoff, or stormwater, poses engineering challenges including increased flood risk and water quality impairment. Stormwater control measures (SCMs) are increasingly used to both mitigate the negative effects of stormwater and capitalize on stormwater as a valuable water resource. SCMs have been shown to provide water quantity benefits such as decreased peak flow and increased groundwater recharge. But the ability of SCMs to reduce pollutants is variable, prompting researchers and practitioners to develop enhanced SCMs with modified geomedia, plant and fungal processes, or hydraulic conditions to provide increased and more reliable pollutant removal. Examples of enhanced SCMs include open surface wetlands, biochar-amended biofilters, and detention ponds with real-time controls. This dissertation focuses on how these next generation SCMs can provide laboratory- and watershed-scale benefits. Chapter 2 investigates the use of wood-decay fungi to enhance biodegradation processes in stormwater at the laboratory scale. Batch studies indicate that the wood-decay fungi are capable of degrading the urban-use pesticide fipronil. Chapters 3 and 4 investigate the impacts of enhanced SCMs on stormwater quality at the watershed scale. Chapter 3 examines effects of implementing enhanced SCMs on fecal indicator bacteria (FIB) pollution in the Ballona Creek Watershed (Los Angeles County, CA). Chapter 4 examines urban-use pesticide occurrence in runoff and subsequent watershed-scale management of pesticides with SCMs in the San Diego River (San Diego County, CA). This work reveals enhanced SCMs provide water quality benefits in the laboratory that are scalable to the watershed level. Further, water managers should consider water quality and quantity goals concurrently when designing SCM networks.

Enhancing the Storm Water Treatment Performance of Constructed Wetlands and Bioretention Basins
Author: Isri R. MangangkaPublisher: Springer
ISBN: 9811016607
Category : Science
Languages : en
Pages : 87
Book Description
This book identifies the key hydrologic and hydraulic factors which influence the performance of stormwater quality treatment systems such as constructed wetlands and bioretention basins. Mathematical relationships derived using conceptual models underpinned by fundamental hydraulic theory are presented to predict treatment performance. The key highlights of the book will include the identification of the linkages between influential hydrologic and hydraulic factors for constructed wetlands and bioretention basins to support more accurate prediction of treatment performance and effective design of these types of stormwater treatment systems. Furthermore, this book will showcase an innovative approach for using conceptual models to analyze stormwater treatment system performance.
Innovative Urban Wet-Weather Flow Management Systems

Book Description
The 20th century's automobile-inspired land use changes brought about tremendous transformations in how stormwater moves across the modern urban land-scape. Streets and parking areas in the average urban family's neighborhood now exceed the amount of land devoted to living space. Add parking, office and commercial space, and it's easy to understand how modern cities have experienced a three-fold increase in impervious areas. Traditional wet weather collection systems removed stormwater from urban areas as quickly as possible, often transferring problems downstream. Innovative Urban WetWeather Flow Management Systems does two things: It considers the physical, chemical, and biological characteristics of urban runoff; then describes innovative methods for improving wet weather flow (WWF) management systems. The result of extensive research, Innovative Urban Wet-Weather Flow Manage-ment Systems looks most at how to handle runoff in developments of the 21st century: the confl icting objectives of providing drainage while decreasing stormwater pollutant discharges; the impact of urban WWF on surface and groundwater, such as smaller urban stream channels scoured by high peak flows; sediment transport and the toxic effects of WWF on aquatic organisms; the effectiveness of WWF controls-including design guidelines and source and downstream controls-are an important issue. Innovative Urban Wet-Weather Flow Management Systems looks at how source controls like biofi ltration, created through simple grading, may work in newly developing areas, while critical source areas like an auto service facilities, may need more extensive treatment strategies. Focusing WWF treatment on intensively used areas, such as the 20 percent of streets that handle the bulk of the traffic, and under utilized parking areas is also considered. Developing a more integrated water supply system-collecting, treating, and disposing of wastewater, and handling urban WWF-requires innovative methods, such as a neighborhood-scale system that would recycle treated wastewater and storm water for lawn watering and toilet flushing, or use treated roof runoff for potable purposes.

Guidance for Evaluating Emerging Stormwater Treatment Technologies
Author: Role of Rainfall and Catchment Characteristics on Urban Stormwater Quality
Author: An LiuPublisher: Springer
ISBN: 9812874593
Category : Science
Languages : en
Pages : 102
Book Description
The key highlights of the book include an innovative rainfall classification methodology based on stormwater quality to support the planning and design of stormwater treatment systems. Additionally, this book provides a practical approach to effective stormwater treatment design and development of a methodology for rainfall selection to optimize stormwater treatment based on both its quality and quantity. The case study presented in this book evaluates how pollutant buildup on urban surfaces and stormwater runoff quality varies with a range of catchment characteristics based on different rainfall types. The information presented will be of particular interest to practitioners such as stormwater-treatment designers, urban planners and hydrologic and stormwater-quality model developers since the outcomes presented provide practical approaches to and recommendations for urban stormwater-quality improvement. Readers will benefit from a state-of-the-art critical review of literature on urban stormwater quality, an in-depth discussion on stormwater-quality processes providing guidance for engineering practice such as stormwater treatment design and model development, a comprehensive overview on the application of multivariate data analysis techniques and a paradigm of the integrated use of commercial models and mathematical equations to undertake a comprehensive, urban stormwater-quality investigation.
Optimizing Stormwater Treatment Practices

Book Description
Optimizing Stormwater Treatment Practices: A Handbook of Assessment and Maintenance provides the information necessary for developing and operating an effective maintenance program for stormwater treatment. The book offers instructions on how to measure the level of performance of stormwater treatment practices directly and bases proposed maintenance schedules on actual performance and historical maintenance efforts and costs. The inspection methods, which are proven in the field and have been implemented successfully, are necessary as regulatory agencies are demanding evaluations of the performance of stormwater treatment practices. The authors have developed a three-tiered approach that offers readers a standard protocol for how to determine the effectiveness of stormwater treatment practices currently in place.
