Force Main Engineering Design

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.
This PVC Pipe News article shows sample calculations for the three design checks for selecting the appropriate class of PVC pipe for a particular force main project. The title is "PVC Force Main Design Example."
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.


Thrust restraint is needed for changes in diameter or changes in direction. The Thrust Restraint Calculator enables engineers and designers to quickly determine the thrust restraint needs of PVC piping systems. The PVC pipe industry offers a full line of thrust restraint products to meet every project need. Please contact one of our Regional Engineers for specific product and design questions.
