Twort's Water Supply, Seventh Edition, has been expanded to provide the latest tools and techniques to meet engineering challenges over dwindling natural resources. Approximately 1.1 billion people in rural and peri-urban communities of developing co
Structural design in general is based on the pipe cross section. Longitudinal bending arising from uneven trench support is not usually specifically considered except where pipes are designed to be supported at discrete intervals or at connections to
