Tackling a Gravity Flow Water Project for the first time? This book is intended to get you on your feet quickly. You'll learn how to select pipe sizes, work out the demand you need to meet, interpret topographic surveys and perform economic calculations to compare different alternatives. Besides producing a sound design, it will help you to get to grips with the materials, put in orders, supervise the building work, and most of what you will need in your quest for access to safe water.
This book discusses the issues and stages in the development of water supplies, from the initiation of a programme through to the community management of a supply system. The importance of involving all the members of a community in decisions about water provision is emphasised, as is the need to incorporate hygiene education.
Many of the world's population lives in villages and rural areas without access to safe water sources or basic sanitation. This guide has been developed as part of the 'healthy villages' project to improve the health of rural communities by promoting local awareness and actions by community groups. It covers topics including: water and sanitation, drainage, waste management, housing quality, domestic and community hygiene, and provision of local health services.
Public water systems deliver high-quality water to the public. They also present a vast array of problems, from pollution monitoring and control to the fundamentals of hydraulics and pipe fitting.
This textbook teaches how to design drinking water systems and to do the calculations by hand. With minimal theory and through 28 progressive exercises, the most common scenarios are introduced one by one: branch lines, joining multiple sources, valley passes, pressure zones, and looped systems. Following simple, quick and reliable guidelines to achieve clear and tangible results for gravity flow water projects, the reader will learn how to decide on pipe diameters, check an existing design, and plan a system enlargement.
