Gravity Flow Water Supply

Gravity Flow Water Supply

Conception, design and sizing for Cooperation Projects


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.  Read online >


 
How
                      to Design a Gravity Flow Water System





How to design a Gravity Flow Water System

Through worked exercises


This book will provide you with the tools for designing drinking water systems and doing 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 even looped systems.

You will learn how to decide on pipe diameters, check an existing design or plan a system enlargement, following simple, quick and reliable guidelines to achieve clear and tangible results for gravity flow water projects.    Read online >
