Educational Webinars

PVC Pipe Association Webinar Series

Welcome to the PVC Pipe Association's online webinar training series. Our webinars offer educational and informative workshops on an on-going basis to support the use of PVC piping in water and wastewater systems. Webinars include examples of how PVC pipe has benefited utilities across North America.

We also provide customized webinars on the design, specification and installation of PVC pipe for water and sewer projects. Let us know if you would like us to organize a webinar for your organization by emailing

New Cyclic Pressure Design Method for PVC Pipe

December 02, 2020 10:30 AM Enroll

Ideal for Utility Engineers and Engineering ConsultantsSewer Force Main Standards

Owing to its strength and durability, PVC has been one of the most widely used pipe materials for force main applications in North America since the 1970s. However, there is an incomplete understanding by some in the utility sector regarding the effect of cyclic surge pressures on PVC pipe. A better understanding of PVC pipe's excellent cyclic pressure handling capabilities enables design engineers to optimize performance. Knowing how PVC pipe handles cyclic surge events allows for the most economical and efficient design of PVC force mains.

This webinar will provide an in-depth review of the PVC Pipe Association's (PVCPA) new design method to determine the cyclic life of PVC pipe under cyclic pressure surges. This new method is simple to use and based on testing and recent research by Dr. Steven Folkman at Utah State University's Buried Structures Laboratory. Examples will be provided showing how this method can be used for the design or condition assessment of PVC force mains.

Additionally, the history of cyclic testing for PVC pipe will be discussed, and participants will get a first-hand look at PVCPA's new online Cyclic Design Calculator. The calculator provides a quick and easy way to accurately determine the cyclic life of PVC pipe under repeated pressure surge events, significantly simplifying the design process. Finally, installation considerations for PVC used in force main applications will be covered.

Cyclic Surge Pressure: PPI’s “PACE” Is Not For PVC Pressure PipeThe 30-minute webinar will cover the following topics:

  • New cyclic life equation for PVC pipe
  • History of cyclic testing
  • Force main design examples
  • Cyclic Design Calculator
  • Condition assessment of PVC force mains
  • Installation considerations for PVC force mains

Utilizing Online Design Calculators for PVC Pipe

December 09, 2020 10:30 AM Enroll

Ideal for Water & Sewer Utilities and Engineering Consultants

Internal Pressure Design CalculatorPVC Pipe Association (PVCPA) engineers will provide an overview of PVCPA's online design calculators for PVC piping applications. Participants will learn how the Internal Pressure Design Calculator can assist engineers to determine PVC pipe wall thickness using expected design values for working pressure, surge pressures (both occasional and recurring) and hydrostatic test pressure based on pipe size and OD regimen.

As well, the External Load Design Calculator, which enables designers to easily determine long-term deflection of PVC pipe given specified embedment (backfill) and pipe material properties, will be discussed. Users can vary inputs such as pipe size, wall thickness, soil properties, live loading conditions and depths of cover.

The webinar will also go over the new Cyclic Design Calculator, which was developed by PVCPA and Dr. Steven Folkman at Utah State University's Buried Structures Laboratory. It provides a quick and simple way to calculate the cyclic life of PVC pipe subjected to recurring surge events.

Using real design variables and inputs, this presentation will go through the functioning of each calculator and how they can assist with PVC pipe design for utility projects. The calculators are intended to be design aids. Conservative assumptions have been used to provide a conservative design and users are responsible for their proper use for all projects.
