This manual has been developed based on experience which was derived from engineering judgment and applied theory. Its purpose is to provide the information necessary to evaluate for feasibility, as well as to plan and design, surface and subsurface infiltration systems or combination systems that can be incorporated into the overall drainage scheme of a particular transportation facility, street system, or commercial development. Basic criteria are presented with examples cited to assist the designer in selecting an appropriate system.
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.
The NPDES Storm Water Sampling Guidance Document provides a comprehensive description of basic sampling requirements for NPDES storm water discharge permit applications and offers procedural guidance on how to conduct sampling. Many of the procedures in this manual are also applicable to the sampling requirements contained in NPDES storm water permits. Topics covered include background information and a summary of permit application requirements, the fundamentals of sampling (including obtaining flow data, handling samples, and sending them to the lab), analytical considerations, regulatory flexibility regarding storm water sampling, and health and safety considerations. This book will be a cornerstone of NPDES compliance for wastewater treatment plant managers and supervisors, consultants, laboratories, lab managers and chemists, regulators, current NPDES permit holders, and anyone applying for an NPDES permit.
This technical release analyzes the effects of urbanization in a watershed on hydraulic and hydrologic parameters and presents methods of estimating runoff volume and peak rates of discharge.
This professional reference tool combines basic concepts ofhydrology with the latest applications for landscape architectureand site engineering--including effective, eco-friendly, andpeople-friendly design methods for: * Wetlands construction * Groundwater recharge * Infiltration * Porous pavements * Stream restoration * Water harvesting Stormwater management is an essential component of all landscapearchitecture and site engineering projects. Introduction toStormwater helps solve environmental problems that arise in theprocess of planning, implementing, and evaluating the builtenvironment. This useful guide is of singular importance to landscapearchitects, civil engineers, architects, wetlands scientists, andother environmental professionals who must comply withever-changing government regulations. Concepts such as drainage,runoff quality, and drought control are presented in aneasy-to-learn, nontechnical format, using case studies drawn fromall regions of the United States. Over 200 charts, tables,photographs, and examples aid in conceptualization andcalculations. Each chapter contains exercises to ensure that theuser acquires applied skills essential to professional licensureexams and practice in the field, as well as information on relatedsoftware.
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.
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.
