This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

Step-by-step procedures for planning, design, construction and operation: * Health and environment * Process improvements * Stormwater and combined sewer control and treatment * Effluent disposal and reuse * Biosolids disposal and reuse * On-site treatment and disposal of small flows * Wastewater treatment plants should be designed so that the effluent standards and reuse objectives, and biosolids regulations can be met with reasonable ease and cost. The design should incorporate flexibility for dealing with seasonal changes, as well as long-term changes in wastewater quality and future regulations. Good planning and design, therefore, must be based on five major steps: characterization of the raw wastewater quality and effluent, pre-design studies to develop alternative processes and selection of final process train, detailed design of the selected alternative, contraction, and operation and maintenance of the completed facility. Engineers, scientists, and financial analysts must utilize principles from a wide range of disciplines: engineering, chemistry, microbiology, geology, architecture, and economics to carry out the responsibilities of designing a wastewater treatment plant. The objective of this book is to present the technical and nontechnical issues that are most commonly addressed in the planning and design reports for wastewater treatment facilities prepared by practicing engineers. Topics discussed include facility planning, process description, process selection logic, mass balance calculations, design calculations, and concepts for equipment sizing. Theory, design, operation and maintenance, trouble shooting, equipment selection and specifications are integrated for each treatment process. Thus delineation of such information for use by students and practicing engineers is the main purpose of this book.

Design-Build construction has become so widely accepted that owners and their advisors must seriously consider this approach when making decisions about project delivery. With its opportunities for cost containment and substantial risk transfer, Design-Build is increasingly becoming the delivery method of choice for owners with challenging funding limitations. But deciding to use the Design-Build system for underground projects is one thing; successfully implementing it is quite another. Design-Build Subsurface Projects, Second Edition, can help bridge that gap. First published in 2002, this cutting-edge book provides a straightforward, comprehensive look at how to make Design-Build work on complicated projects involving tunnels, highways, dams, and deep foundations. The authors are a "who's who" of subsurface construction experts, many of whom are key players in the most high-profile and challenging projects in the world. Drawing upon their wealth of practical experience, they spell out a list of common sense best practices that can be used by today's project owners and designers. Be advised: these authors don't shy away from the many thorny issues of Design-Build. Nor are they unabashed cheerleaders. They dispassionately explore both the advantages and disadvantages of this system, which must be carefully weighed and evaluated so planners can decide what is best for their projects based on all the important variables, including third-party impacts and environmental/community concerns. You'll find extensive information about procurement, as well as risk allocation issues, which are significantly different from the Design-Bid-Build approach. Team structure, agreements, design development, subsurface exploration, geotechnical reports, construction phase issues, and insurance are also examined in great detail. Design-Build Subsurface Projects is an indispensable resource for owners, engineers, construction managers, contractors, and others involved in the design and construction of subsurface projects. You'll gain a thorough understanding of how and why the system works and where the pitfalls can arise. The authors' years of experience will benefit even the most seasoned of practitioners.
