Flexible pipes rely on the surrounding soil for structural support. When an external load is applied, the pipe deflects slightly, transferring the vertical load into lateral pressure against the sidefill soil. AWWA M55 provides the mathematical framework—utilizing the Modified Iowa Equation—to calculate expected pipe deflection based on soil density, depth of cover, and the pipe’s Dimension Ratio (DR). 3. Monolithic, Leak-Free Joints
