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.
This document has been developed by the Uni-Bell PVC Pipe Association for design and installation of PVC fittings where solid-wall PVC pipe is used in non-pressure applications. The guide provides information on the wide range of fittings that are available for various dimension ratios and outside diameters of PVC pipe through 60-inch. Also included is information on installation practices.
PVC Sewer Pipe Standards are summarized on a single sheet. Both sanitary sewer and storm drainage standards are listed.
This comparison of PVC and fiberglass gravity sewer pipes is based on decades of flexible-pipe research and field experience. A review of the properties and capabilities of both materials shows PVC to be the better choice.
