Every ten seconds a child dies from diarrhoea. This makes 3 million children every year, or over 8000 children per day. These figures are only counting the deaths. How many children are disabled for life by parasitic infections and frequent diarrhoea in their early years? How many women live with permanent anaemia because of hookworm infections?;This book provides a practical solution to the lack of basic facilities and sanitation that so many people face in the world today, by giving advice and information on how to set up and implement a latrine building programme, and providing guidelines on how to build latrines that are easily maintained, affordable and appropriate to the needs of the communities who will be using them.;The book gives a basic introduction to appropriate latrine building, and covers the design and construction of different types of latrines, discussing some of the common problems that can occur in the building stage. It covers all aspects of the implementation of a latrine building programme, including the promoting of hygiene and the education aspects of such a programme, and how to go about planning, monitoring and evaluating such a programme. The latrine designs described here can be built using local materials, and involve peoples traditional skills and innovations.

The treadle irrigation pump is able to lift up to 7000 litres of water per hour using the power of the human body, and can be locally made at low cost in small-scale metalworking shops. Its acceptance in Bangladesh, where it was first developed in 1984, is extraordinary, with over 500,000 pumps estimated now to be in use.;The current design offered in this manual has evolved from the Bangladesh original into a fully portable pump with both lift and pressure capacity and is especially appropriate to situations where soils are permeable, and water cannot easily be distributed through channels. The manual is intended to be read primarily by organizations engaged in economic development activities which have a particular expertise in technology transfer; it is not intended just as a step-by-step guide for the manufacturer (although it can be used in this way).

The modern definition of firefighter no longer means "putting the wet stuff on the red stuff." Emergency responders answer incidents ranging from fire alarm activations to elevator rescues and medical emergencies more often than full-blown fires. Consequently, responders increasingly interface with a wide array of building systems. Underscoring the changing role of firefighters, Fire Protection: Systems and Response presents the basic knowledge of the inner workings of fire safety/fire protection systems and related equipment in buildings.

The author provides a straightforward overview of the functions and benefits of these systems and how they can assist with fire suppression, code enforcement, alarm response, and elevator rescue. The book's comprehensive discussion of elevators, fire command centers, emergency generators and lighting, and HVAC systems sets it apart from other fire protection books currently available. The topics covered prepare emergency response personnel for the challenges they face working with fire protection systems, fire alarm systems, and elevators.

Logically organized, clearly written, and covering all systems in a single text, this presentation of information streamlines fire service interaction with building features and fire protection systems. Providing an understanding of how systems are designed and installed, the book is also a reference for troubleshooting fire protection problems in the field. The information not only gives responders an appreciationknowledge of how the systems work, but helps them use this knowledge to perform their job better.

Popular belief holds that throwing the contents of a chamber pot into the street was a common occurrence during the early modern period. This book challenges this deeply entrenched stereotypical image as the majority of urban inhabitants and their local governors alike valued clean outdoor public spaces, vesting interest in keeping the areas in which they lived and worked clean. Taking an extensive tour of over thirty towns and cities across early modern Britain, focusing on Edinburgh and York as in-depth case studies, this book sheds light on the complex relationship between how governors organised street cleaning, managed waste disposal and regulated the cleanliness of the outdoor environment, top-down, and how typical urban inhabitants self-regulated their neighbourhoods, bottom-up. The urban-rural manure trade, sanitation infrastructure, waste-disposal technology, plague epidemics, contemporary understandings of malodours and miasmatic disease transmission and urban agriculture are also analysed. This book will enable undergraduates, postgraduates and established academics to deepen their understanding of daily life and sensory experiences in the early modern British town. This innovative work will appeal to social, cultural and legal historians as well as researchers of history of medicine and public health.
