Urban water management has to take an integrated approach that prioritizes sustainable drainage systems (SuDS) over gray infrastructure. This book elaborates on the planning and evaluation of pipework drainage systems with a focus on modern-day constraints to deliver a solution that favors sustainability as the overarching goal. The book includes a technical section on design of gray and green infrastructure, considering the total lifecycle costs of drainage systems. Advanced computer simulation techniques are discussed after covering the derivation of both standard and empirical equations for appropriate hydrology and hydraulics. The book provides an incorporation of reliability analyses for both green and gray infrastructure starting with techniques for forecasting flows, hydraulic performance, and lifecycle costs. The work also involves 3-D modeling, geospatial and big data analysis, and how these techniques are applied into city management—particularly beneficial to municipal engineers who are increasingly becoming involved in mapping the underground. Soil mechanics and subsurface drainage systems are analyzed and structural aspects of sewers are included. Finally, soil behavior in shear, retaining wall structures, and tunneling is briefly featured in the book.This book will be of interest to (under)graduate and postgraduate engineering students, drainage engineers, urban planners, architects, water engineers, developers, construction contractors, and municipal engineers.

This book provides a holistic and clear understanding of water supply, sanitary and storm drainage systems for buildings: one-story to skyscrapers, to be built in both the developed and underdeveloped areas. It describes the systems and their entire components - major to minor - and provides exclusive guidelines for the planning, design, installation and maintenance of the systems. The book starts with an introduction to the systems, and ends with a chapter on the presentation of the systems in drawings, others being discussions on all the components, devices, equipment etc., in their respective dedicated chapters – discussing: Pipe, Fittings, Accessories, and Appurtenance; Pumping and Pumping Systems; Water and Hot Water Supply Systems in Building; Appliances and Fixtures; Building Sanitary Drainage; Off-site Sewage Disposal; On-site Sewage Management; Drainage of Storm Water; and Water Supply and Drainage Planning. Written and the figures are drawn by an author of three engineering books of international repute, the last being the 2nd edition of the first one, who served the Public Works Department of Bangladesh - a national building development authority - for more than 35 years. This book is the fallout of practical experience in the building industry, teaching in universities, facilitating training and sharing thoughts in seminars and symposiums on related subject-matters, since the early 90s until today. Figures being drawn by the author using a rarely-used drawing tool help provide additional attraction to the readers. Additionally, the inclusion of worked out examples of designing the major system-components will undoubtedly bring utmost satisfaction to its readers. This book will be helpful for use in a wide range of courses, both undergraduate and post-graduate degree programs, related to building, environmental and civil engineering, architecture, and many more. Building service professionals will benefit greatly. Other traders, administrators in this field, and policy-makers would not be left out of the beneficiaries as well.

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.What can underground pipes tell us about human eating habits and the spread or containment of disease, such as COVID-19? Why are sewers spitting out plastic and trash into waterways around the world? How are clogs getting gnarlier and more numerous? Jessica Leigh Hester leads readers through the past, present, and future of the system humans have created to deal with our own waste and argues that sewers can be seen as a mirror to the world above at a time when our behaviors are drastically reshaping the environment for the worse. Sifting through the muck offers a fresh way to approach questions about urbanization, public health, infrastructure, ecology, sustainability, and consumerism- and what we value. Without understanding sewers, any attempt to steward the future is incomplete. Object Lessons is published in partnership with an essay series in The Atlantic.

Climate change will present a series of challenges to engineers concerned with the provision of both building internal appliance drainage networks and rainwater systems within the building boundary, generally identified as the connection to the sewer network. Climate change is now recognised as presenting both water shortage and enhanced rainfall design scenarios.In response to predictions about immanent climate change Transient Free Surface Flows in Building Drainage Systems addresses problems such as the reduction in water available to remove waste from buildings, and conversely, the increase in frequency of tropical-type torrential rain. Starting with introductory chapters that explain the theories and principles of solid transport, free surface flows within drainage networks, and attenuating appliance discharge flows, this book allows readers from a variety of backgrounds to fully engage with this crucial subject matter. Later chapters apply these theories to the design of sanitary and rainwater systems. Case studies highlight the applicability of the method in assessing the appropriateness of design approaches.In this unique book, research in modelling for free surface flows at Edinburgh's Heriot-Watt University is drawn on to provide a highly authoritative, physics-based study of this complex engineering issue.

A study of water at the intersection of landscape and infrastructure in Paris, Berlin, Lagos, Mumbai, Los Angeles, and London.Water lies at the intersection of landscape and infrastructure, crossing between visible and invisible domains of urban space, in the tanks and buckets of the global South and the vast subterranean technological networks of the global North. In this book, Matthew Gandy considers the cultural and material significance of water through the experiences of six cities: Paris, Berlin, Lagos, Mumbai, Los Angeles, and London. Tracing the evolving relationships among modernity, nature, and the urban imagination, from different vantage points and through different periods, Gandy uses water as a lens through which to observe both the ambiguities and the limits of nature as conventionally understood. Gandy begins with the Parisian sewers of the nineteenth century, captured in the photographs of Nadar, and the reconstruction of subterranean Paris. He moves on to Weimar-era Berlin and its protection of public access to lakes for swimming, the culmination of efforts to reconnect the city with nature. He considers the threat of malaria in Lagos, where changing geopolitical circumstances led to large-scale swamp drainage in the 1940s. He shows how the dysfunctional water infrastructure of Mumbai offers a vivid expression of persistent social inequality in a postcolonial city. He explores the incongruous concrete landscapes of the Los Angeles River. Finally, Gandy uses the fictional scenario of a partially submerged London as the starting point for an investigation of the actual hydrological threats facing that city.

Urban water services are building blocks for healthy cities, and they require complex and expensive infrastructure systems. Most of the infrastructure is out of sight and tends to be taken for granted, but an infrastructure financing crisis looms in the United States because the systems are aging and falling behind on maintenance. A road map for pu

Available as eBook only. Water plays a critical role in every aspect of civilization: agriculture, industry, economy, environment, recreation, transportation, culture, and health. While clean water and sanitary conditions remain an elusive luxury in many parts of the world, we, as Americans, take them for granted. Much of America's drinking water and wastewater infrastructure; however, is old and deteriorating. A crisis looms as our demands on these systems increase. The costs associated with renewal of these aging systems are staggering. There is a critical disconnect between the methodological remedies for infrastructure renewal problems and the current sequential or isolated manner of renewal analysis and execution. This points to the need for a holistic systems perspective to address the renewal problem. Therefore, new tools are needed to provide support for water infrastructure decisions. Such decisions are necessary to sustain economic growth, environmental quality, and improved societal benefits. Accurate prediction of wastewater pipe structural and functional deterioration plays an essential role in asset management and capital improvement planning. The key to implementing an asset management strategy is a comprehensive understanding of asset condition, performance, and risk profile. The primary objective of this research is therefore to develop protocols and methods for predicting the remaining economic life of wastewater pipes. This report presents a development of a robust performance index for wastewater pipes, including physical/structural, operational/functional, environmental and other parameters, for not only the pipe, but also the entire pipe system. An analysis of data from participating utilities was done to establish the statistical significant of each parameter. These parameters are grouped into pipe properties, internal environment and external environment. The proposed performance rating system evaluates each parameter and combines them mathematically through a weighted summation and a fuzzy inference system that reflects the importance of the various factors. The Performance Index comprises of structural and functional index, and each index evaluates pipes in scale from zero to five, in the pipe rating scale zero indicates the worst condition whereas five indicates the best condition.

As a vital human need, water has been absolutely critical to decisions as to where cities originate, how much they grow and the standard of living of the inhabitants. The relationship is complex however; we need both continual availability and protection from its potential impacts. Over recent decades flooding and scarcity episodes have become commonplace in even the most advanced countries – and these events cannot be disassociated from the socio-economic context within which they occur; being directly related to how we live, where we live and how we govern.This book draws together information on a host of connected subjects from population growth to water scarcity to the relationship between humanity and nature, then demonstrates how utilizing notions of risk and resilience could help improve the relationship between the city and its most precious resource. Combining discussions of risk, water and spatial planning it provides an invaluable text for planning, geography and urban studies students on how to address urban water problems within a rapidly changing world.

The concept for the Water Environment of Cities arose from a workshop “Green 1 Cities, Blue Waters” workshop held in 2006. The workshop assembled experts from engineering, planning, economics, law, hydrology, aquatic ecology, geom- phology, and other disciplines to present research?ndings and identify key new ideas on the urban water environment. At a lunch discussion near the end of the workshop, several of us came to the recognition that despite having considerable expertise in a narrow discipline, none of us had a vision of the “urban water en- ronment” as a whole. We were, as in the parable, blind men at opposite ends of the elephant, knowinga great deal about the parts, but notunderstandingthe whole. We quickly recognized the need to develop a book that would integrate this knowledge to create this vision. The goal was to develop a book that could be used to teach a complete, multidisciplinary course, “The Urban Water Environment”, but could also be used as a supplemental text for courses on urban ecosystems, urban design, landscapearchitecture,water policy,waterqualitymanagement andwatershed m- agement. The book is also valuable as a reference source for water professionals stepping outside their arena of disciplinary expertise. The Water Environment of Cities is the?rst book to use a holistic, interdis- plinary approach to examine the urban water environment. We have attempted to portrayaholisticvisionbuiltaround theconcept of water as a coreelement ofcities. Water has multipleroles:municipalwatersupply,aquatichabitat,landscapeaesth- ics, and recreation. Increasingly, urban water is reused, serving multiple purposes.

According to a report released by the Water Infrastructure Network (WIN), over the next 20 years America's water and wastewater systems will have to invest an additional $20 billion a year to replace aging and failing infrastructure in order to comply with the national environmental and public health priorities in the Clean Water Act and Safe Drink

This Report presents information on the current state of knowledge of the origins, occurrence, nature and effects of sewer solids for use by engineers, scientists, administrators and water quality planners for the planning, design and operation of sewerage systems. The report addresses both sewer maintenance requirements and environmental protection issues. Increasing environmental standards, coupled with public expectations, have led to stringent water quality standards. In response to this, it has been necessary to develop new methodologies and computer based analytical techniques to model and understand the performance of all aspects of waste water systems. Fundamental to these techniques is the understanding of the way in which sewer solids contribute to the poor performance of wastewater systems and consequential environmental damage. The information presented in this Report about the origins, nature, movement, hydraulic and polluting effects of solids in sewers has enabled strategies and rules to be developed for the management of sewerage systems to minimise the deleterious effects of these solids and associated pollutants.

This broad-based book covers topics in sewage treatment from site investigation through to design, construction and operation. Data and design charts are given in an appendix.

Low-cost sewerage provides practical solutions to the sanitation needs of low-income areas. As a result of the currently very rapid urban population growth, the demand for sewerage exceeds the resources of most high density urban areas in developing countries. Low-cost alternatives to conventional sewerage, such as settled sewerage and simplified sewerage, therefore need to be developed. This book is the result of contributions by both academics and practitioners who attended the International Conference on Low-cost Sewerage which was held at the University of Leeds, England, in July 1995. Low-cost sewerage technologies are described and their applications in both developed and developing countries are detailed.
