In 2007, AWWA C900 PVC Pressure Standards were changed to reflect data retrieved from over 30 years experience with PVC pipe products in municipal applications, current research on PVC performance, as well as to harmonize various PVC pressure pipe standards. This article explains the new pressure classes of DR14-305 psi, DR18-235 psi and DR25-165 psi PVC pipe products. Pipe wall thicknesses and outside dimensions stayed the same with this change.

An article entitled "PVC Pressure Pipe Endures Over Ten Million Cycles" discusses research on PVC performance under cyclic loading.

This technical report examines head loss and pumping costs over 100-years for PVC and ductile iron pipe.

Water and sewer hydraulic design are reviewed in Chapter 9 of the Handbook of PVC Pipe Design

PVC Pressure Pipe Standards are summarized on a single sheet

This Uni-Bell technical report, "UNI-TR-6, PVC Force Main Design," details the Association's recommended design procedures for selecting the appropriate class of PVC pressure pipe for force main applications.

In 2016 AWWA published the latest edition of its C900 standard for PVC pipe. C900-16 is more complicated than most standards, primarily because it has absorbed the large-diameter sizes previously found in the C905 standard. To help with the transition from two standards in the past to one standard now, the PVCPA has written a 20-page explanatory guide.
