In 1858 the `Great Stink of London' made much of the city along the Thames uninhabitable. Between 1848 and 1854 nearly 25,000 Londoners died of cholera, a disease borne by foul water. Joseph Bazalgette saved the city, building sewers that would serve 4 million people and stop waste water emptying into the Thames. These sewers are still the backbone of London's sewerage system today, but the city's population is now approaching 10 million; the old sewers can't cope and action needs to be taken to ensure that `The Great Stink' never happens again. This is where the Thames Tideway Tunnel comes in: a GBP4.2 billion, 25km-long, 7.2m-diameter tunnel that will stop virtually all of the sewer overflows into the Thames and give us a cleaner and healthier river and city. This is the inside story on the tunnel, from the very start to breaking ground and all the steps along the way. Written by Phil Stride, a leading civil engineer, it is a unique chance both to see behind the scenes of an incredible civil engineering project and to meet the people who've taken it forward over the last ten years.

Wastes, whether they are solid wastes or wastewater, are resources from which economic values may be derived. Almost all components of agricultural and food wastewater can be and should be utilized or recovered; the stumbling block of achieving this aspiration is economical, not technical. The last one and a half decades have seen the surging of agricultural and non-agricultural commodity prices across the board and increased public consciousness of environmental impact of industrial wastewater discharge and treatment. The confluence of these new developments have generated new interests and applications of agricultural and food wastewater and their treatment residuals in diverse fields and industries. This new edition will expand topics related to wastewater utilizations and new uses of treatment residuals while providing up-to-date information on new treatment technologies and practices across the globe. The new edition s target audience is anyone who has the responsibility of dealing with its plant effluents in agricultural and food processing operations. It should be of value to waste management personnel responsible for managing major waste effluents from agro and food industries. It will also be useful for college students whose majors are in environmental science or waste management fields as a reference.
Although primarily concerned with the treatment of wastewater and water quality, publicly owned treatment works (POTWs) are required to be in compliance with the Federal Clean Air Act and an increasingly stringent series of Clean Air Act Amendments to control emissions of odors, criteria pollutants, and volatile organic compounds (VOCs). How POTWs demonstrate, document, or show compliance with federal and state or local quality laws and regulations can vary significantly from POTW to POTW and from state to state. VOC Emissions from Wastewater Treatment Plants: Characterization, Control, and Compliance provides the tools, concepts, policies, and information required to develop an air quality compliance plan and to assess the labor and capital requirements to maintain the plan's viability.
The focus of the book is on how to use mass and heat balances to simulate and design biological wastewater treatment processes. All the main processes for biological wastewater treatment are covered viz. activated sludge processes for carbon and nitrogen removal, anaerobic digestion, sequencing batch reactors, and attached growth processes.
Sanitation remains one of the biggest development challenges of our time, and a long neglected issue associated with taboos and stigma. Despite growing attention and efforts, many top-down approaches to sanitation have failed, reflecting that simply providing people with a toilet does not necessarily guarantee its use. The Community-Led Total Sanitation (CLTS) approach offers a more promising alternative, focusing on facilitating a profound change in people s behavior through participatory techniques. By raising local people s awareness of the linkages between open defecation and disease through the release of powerful emotions such as disgust and shame, they are encouraged to analyze their own sanitation situation and take action themselves.The approach has proved immensely successful, being implemented in more than 20 countries, and has a big potential in terms of achieving several Millennium Development Goals. However, like any development success story, challenges still remain regarding scaling up with quality, inclusion of the poorest and sustainability and there is a danger that accounts of success may be exaggerated. This book addresses both the potential and challenges of CLTS by drawing on research in Bangladesh, India and Indonesia as well as experiences from Africa.With chapters by leading scholars and practitioners in sanitation policy and practice as well as critical reflections from key players in CLTS, "Shit Matters" offers important insights into the workings of CLTS on the ground, covering critical aspects of the social, ecological, technological, financial and institutional dynamics surrounding CLTS. It will be essential reading for anyone interested in development, health, public policy and sanitation issues."
There are a growing number of new chemicals in the environment that represent an ascertained or potential risk. Many of them can be found in sewage sludge and are the subject of this volume. Experts in the field highlight their occurrence and fate, risks of biosolid use, advanced chemical analysis methods, and degradation techniques with a special focus on biodegradation using fungi. In the final chapter conclusions and trends are offered as a point of departure for future studies. The double-disciplinary approach combining environmental analysis and engineering makes the book a valuable and comprehensive source of information for a broad audience, such as environmental chemists and engineers, biotechnologists, ecotoxicologists and professionals responsible for waste and water management.
"In the rainy season it is really bad. Water mixes with the shit and when we carry it on our heads, it drips from the basket onto our clothes, our bodies, our faces. When I return home, I find it difficult to eat food sometimes. The smell never gets out of my clothes, my hair. But then in summer there is often no water to wash your hands before eating. It is difficult to say which is worse." This is a telling investigation and indictment of India`s lack of resolve over the past 100 years to get rid of manual scavenging and transportation of human excrement. Since Gandhi raised the question of untouchability in 1901 there have been reports, recommendations, a National Commission in 1994 and allocation of funds for rehabilitation of the Bhangis, but so far little has changed. Almost every state government denies the existence of the problem. The author suggests that there is a silent and shameful opposition in India to the eradication of untouchability. The Bhangis are trapped in a system ordained by the caste structure which impedes rehabilitation and movement into alternative work. Can attitudes change, or will the dignity, justice and equality enshrined in the Constitution remain no nearer for the Bhangis than it was in 1947?

In the sweltering summer of 1858 the stink of sewage from the polluted Thames was so offensive that it drove Members of Parliament from the chamber of the House of Commons. Sewage generated by a population of over two million Londoners was pouring into the river and was being carried to and fro by the tides. The Times called the crisis "The Great Stink." Parliament had to act - drastic measures were required to clean the Thames and to improve London's primitive system of sanitation. The great engineer entrusted by Parliament with this enormous task was Sir Joseph Bazalgette. This book is an account of his life and work.
