Charts providing deflection at burial depths up to 100 feet. Graphs are for DR35 and Heavy Wall DR26.
Water and sewer hydraulic design are reviewed in Chapter 9 of the Handbook of PVC Pipe Design.
Seven PVC Sewer Pipe Standards are summarized on a single sheet. Both sanitary sewer and storm drainage standards are summarized.
Photo demonstrates how flexible PVC can be used in shallow burial applications.
This Uni-Bell Technical Report, "Deflection: The Pipe/Soil Mechanism," details design procedures for predicting long-term deflection of buried PVC pipe.
